Despite the increasing interest toward environmental issues in the freight transport and logistics service sector, a comprehensive and updated assessment of the existing literature is still missing. This paper aims to fill this gap by presenting the results of a systematic literature review of publications in the area of environmental sustainability in third-party logistics service providers (3PLs) between the years 2000 and 2016. The review offers insight into the critical dimensions of green matters in transport and logistics service companies using an analytical framework based on the following five topic areas: influencing factors, green actions and the impact on performance, Information and Communication Technology (ICT) tools supporting the green actions, energy efficiency in road freight transport and shipper’s perspective and collaboration. The results indicate that, despite the number of published papers having grown significantly from 2008 onward, some areas remain highly under-researched such as ICT and performance measurement. Several research gaps have been identified in each topic area, and a set of propositions forming an agenda for future research directions has been suggested.

Precision measurement of the \\({\\cal B}(\\Upsilon(3S)\\to\\tau^+\\tau^-)/{\\cal B}(\\Upsilon(3S)\\to\\mu^+\\mu^-)\\) ratio
2020
We report on a precision measurement of the ratio \\({\\cal R}_{\\tau\\mu}^{\\Upsilon(3S)} = {\\cal B}(\\Upsilon(3S)\\to\\tau^+\\tau^-)/{\\cal B}(\\Upsilon(3S)\\to\\mu^+\\mu^-)\\) using data collected with the BaBar detector at the SLAC PEP-II \\(e^+e^-\\) collider. The measurement is based on a 28 fb\\(^{-1}\\) data sample collected at a center-of-mass energy of 10.355 GeV corresponding to a sample of 122 million \\(\\Upsilon(3S)\\) mesons. The ratio is measured to be \\({\\cal R}_{\\tau\\mu}^{\\Upsilon(3S)} = 0.966 \\pm 0.008_\\mathrm{stat} \\pm 0.014_\\mathrm{syst}\\) and is in agreement with the Standard Model prediction of 0.9948 within 2 standard deviations. The uncertainty in \\({\\cal R}_{\\tau\\mu}^{\\Upsilon(3S)}\\) is almost an order of magnitude smaller than the only previous measurement.
Search for \\(B\\) Mesogenesis at BABAR
2023
A new mechanism has been proposed to simultaneously explain the presence of dark matter and the matter-antimatter asymmetry in the universe. This scenario predicts exotic \\(B\\) meson decays into a baryon and a dark sector anti-baryon (\\(\\psi_D\\)) with branching fractions accessible at \\(B\\) factories. We present a search for \\(B \\rightarrow \\Lambda \\psi_D\\) decays using data collected by the \\(BABAR\\) experiment at SLAC. This reaction is identified by fully reconstructing the accompanying \\(B\\) meson and requiring the presence of a single \\(\\Lambda\\) baryon in the remaining particles. No significant signal is observed, and bounds on the \\(B \\rightarrow \\Lambda \\psi_D\\) branching fraction are derived in the range \\(0.13 - 5.2\\times 10^{-5}\\) for \\(1.0 < m_{\\psi_D} < 4.2\\) GeV/\\(c^{2}\\). These results set strong constraints on the parameter space allowed by the theory.
Measurements of the Absolute Branching Fractions of \\(B^\\pm \\to K^\\pm X_{c\\bar c}\\)
2020
A study of the two body decays \\(B^\\pm\\rightarrow X_{c\\bar c}K^\\pm\\), where X\\(_{c\\bar c}\\) refers to one charmonium state, is reported by BaBar collaboration using a data sample of 424 fb\\(^{-1}\\). The absolute determination of branching fractions for these decays are significantly improved compared to previous BaBaR measurements. Evidence is found for the decay \\(B^+\\rightarrow X(3872)K^+\\) at the \\(3\\sigma\\) level. The absolute branching fraction \\({\\cal B}(B^+\\rightarrow X(3872)K^+) = (2.1\\pm0.6({\\rm stat})\\pm0.3({\\rm syst}))\\times 10^{-4}\\) is measured for the first time. It follows that \\({\\cal B}(X(3872)\\rightarrow J/\\psi\\pi^+\\pi^-)=(4.1\\pm1.3)\\%\\), supporting the hypothesis of a molecular component for this resonance.

We present a search for seven lepton-flavor-violating neutral charm decays of the type \\(D^{0}\\rightarrow X^{0} e^{\\pm} \\mu^{\\mp}\\), where \\(X^{0}\\) represents a \\(\\pi^{0}\\), \\(K^{0}_{\\rm S}\\), \\(\\bar{K^{*0}}\\), \\(\\rho^{0}\\), \\(\\phi\\), \\(\\omega\\), or \\(\\eta\\) meson. The analysis is based on \\(468\\) fb\\(^{-1}\\) of \\(e^+e^-\\) annihilation data collected at or close to the \\(\\Upsilon(4S)\\) resonance with the BaBar detector at the SLAC National Accelerator Laboratory. No significant signals are observed, and we establish 90\\% confidence level upper limits on the branching fractions in the range \\((5.0 - 22.5)\\times 10^{-7}\\). The limits are between one and two orders of magnitude more stringent than previous measurements.

We present a search for nine lepton-number-violating and three lepton-flavor-violating neutral charm decays of the type \\(D^0\\rightarrow h^{\\prime -} h^{-}\\ell^{\\prime +} \\ell^{+}\\) and \\(D^0\\rightarrow h^{\\prime -} h^{+}\\ell^{\\prime\\pm} \\ell^{\\mp}\\), where \\(h\\) and \\(h^{\\prime}\\) represent a \\(K\\) or \\(\\pi\\) meson and \\(\\ell\\) and \\(\\ell^{\\prime}\\) an electron or muon. The analysis is based on \\(468\\) fb\\(^{-1}\\) of \\(e^+e^-\\) annihilation data collected at or close to the \\(Y(4S)\\) resonance with the BaBar detector at the SLAC National Accelerator Laboratory. No significant signal is observed for any of the twelve modes and we establish 90% confidence level upper limits on the branching fractions in the range \\((1.0 - 30.6)\\times 10^{-7}\\). The limits are between one and three orders of magnitude times more stringent than previous measurements.
Search for \\(B^- \\to \\Lambda \\bar p \\nu \\bar\\nu\\) with the BABAR experiment
2019
We search for the rare flavor-changing neutral current process \\(B^- \\to \\Lambda {\\overline p} \\nu{\\overline{\\nu}}\\) using data from the BABAR experiment. A total of 424 fb\\(^{-1}\\) of \\(e^+e^-\\) collision data collected at the center-of-mass energy of the \\(\\Upsilon\\)(4S) resonance is used in this study, corresponding to a sample of \\({(471 \\pm 3) \\times 10^{6}}\\) \\(B\\overline{B}\\) pairs. Signal \\(B^- \\to \\Lambda {\\overline p} \\nu{\\overline{\\nu}}\\) candidates are identified by first fully reconstructing a \\(B^+\\) decay in one of many possible exclusive decays to hadronic final states, then examining detector activity that is not associated with this reconstructed \\(B^+\\) decay for evidence of a signal \\(B^- \\to \\Lambda {\\overline p} \\nu{\\overline{\\nu}}\\) decay. The data yield is found to be consistent with the expected background contribution under a null signal hypothesis, resulting in an upper limit of \\({{\\cal B} (B^- \\to \\Lambda {\\overline p} \\nu{\\overline{\\nu}}) < 3.0\\times 10^{-5}}\\) at the \\(90\\%\\) confidence level.
Measurement of \\(\\cos{2\\beta}\\) in \\(B^{0} \\to D^{()} h^{0}\\) with \\(D \\to K_{S}^{0} \\pi^{+} \\pi^{-}\\) decays by a combined time-dependent Dalitz plot analysis of BaBar and Belle data
2018
We report measurements of \\(\\sin{2\\beta}\\) and \\(\\cos{2\\beta}\\) from a time-dependent Dalitz plot analysis of \\(B^{0} \\to D^{(*)} h^{0}\\) with \\(D \\to K_{S}^{0} \\pi^{+} \\pi^{-}\\) decays, where the light unflavored and neutral hadron \\(h^{0}\\) is a \\(\\pi^{0}\\), \\(\\eta\\), or \\(\\omega\\) meson. The analysis is performed with a combination of the final data sets of the \\babar\\ and Belle experiments containing \\(471 \\times 10^{6}\\) and \\(772 \\times 10^{6}\\) \\(B\\bar{B}\\) pairs collected at the \\(\\Upsilon\\left(4S\\right)\\) resonance at the asymmetric-energy B factories PEP-II at SLAC and KEKB at KEK, respectively. We measure \\(\\sin{2\\beta} = 0.80 \\pm 0.14 \\,(\\rm{stat.}) \\pm 0.06 \\,(\\rm{syst.}) \\pm 0.03 \\,(\\rm{model})\\) and \\(\\cos{2\\beta} = 0.91 \\pm 0.22 \\,(\\rm{stat.}) \\pm 0.09 \\,(\\rm{syst.}) \\pm 0.07 \\,(\\rm{model})\\). The result for the direct measurement of the angle is \\(\\beta = \\left( 22.5 \\pm 4.4 \\,(\\rm{stat.}) \\pm 1.2 \\,(\\rm{syst.}) \\pm 0.6 \\,(\\rm{model}) \\right)^{\\circ}\\). The last quoted uncertainties are due to the composition of the \\(D^{0} \\to K_{S}^{0} \\pi^{+} \\pi^{-}\\) decay amplitude model, which is newly established by a Dalitz plot amplitude analysis of a high-statistics \\(e^{+}e^{-} \\to c\\bar{c}\\) data sample as part of this analysis. We find the first evidence for \\(\\cos2\\beta>0\\) at the level of \\(3.7\\) standard deviations. The measurement excludes the trigonometric multifold solution \\(\\pi/2 - \\beta = (68.1 \\pm 0.7)^{\\circ}\\) at the level of \\(7.3\\) standard deviations and therefore resolves an ambiguity in the determination of the apex of the CKM Unitarity Triangle. The hypothesis of \\(\\beta = 0^{\\circ}\\) is ruled out at the level of \\(5.1\\) standard deviations, and thus CP violation is observed in \\(B^{0} \\to D^{(*)} h^{0}\\) decays.
First evidence for \\(\\cos 2\\beta>0\\) and resolution of the CKM Unitarity Triangle ambiguity by a time-dependent Dalitz plot analysis of \\(B^{0} \\to D^{()} h^{0}\\) with \\(D \\to K_{S}^{0} \\pi^{+} \\pi^{-}\\) decays
2018
We present first evidence that the cosine of the CP-violating weak phase \\(2\\beta\\) is positive, and hence exclude trigonometric multifold solutions of the CKM Unitarity Triangle using a time-dependent Dalitz plot analysis of \\(B^{0} \\to D^{(*)} h^{0}\\) with \\(D \\to K_{S}^{0} \\pi^{+} \\pi^{-}\\) decays, where \\(h^{0} \\in \\{\\pi^{0}, \\eta, \\omega \\}\\) denotes a light unflavored and neutral hadron. The measurement is performed combining the final data sets of the BaBar and Belle experiments collected at the \\(\\Upsilon(4S)\\) resonance at the asymmetric-energy B factories PEP-II at SLAC and KEKB at KEK, respectively. The data samples contain \\(( 471 \\pm 3 )\\times 10^6\\, B\\bar{B}\\) pairs recorded by the BaBar detector and \\(( 772 \\pm 11 )\\times 10^6\\, B\\bar{B}\\) pairs recorded by the Belle detector. The results of the measurement are \\(\\sin{2\\beta} = 0.80 \\pm 0.14 \\,(\\rm{stat.}) \\pm 0.06 \\,(\\rm{syst.}) \\pm 0.03 \\,(\\rm{model})\\) and \\(\\cos{2\\beta} = 0.91 \\pm 0.22 \\,(\\rm{stat.}) \\pm 0.09 \\,(\\rm{syst.}) \\pm 0.07 \\,(\\rm{model})\\). The result for the direct measurement of the angle \\(\\beta\\) of the CKM Unitarity Triangle is \\(\\beta = \\left( 22.5 \\pm 4.4 \\,(\\rm{stat.}) \\pm 1.2 \\,(\\rm{syst.}) \\pm 0.6 \\,(\\rm{model}) \\right)^{\\circ}\\). The quoted model uncertainties are due to the composition of the \\(D^{0} \\to K_{S}^{0} \\pi^{+} \\pi^{-}\\) decay amplitude model, which is newly established by performing a Dalitz plot amplitude analysis using a high-statistics \\(e^{+}e^{-} \\to c\\bar{c}\\) data sample. CP violation is observed in \\(B^{0} \\to D^{(*)} h^{0}\\) decays at the level of \\(5.1\\) standard deviations. The significance for \\(\\cos{2\\beta}>0\\) is \\(3.7\\) standard deviations. The trigonometric multifold solution \\(\\pi/2 - \\beta = (68.1 \\pm 0.7)^{\\circ}\\) is excluded at the level of \\(7.3\\) standard deviations. The measurement resolves an ambiguity in the determination of the apex of the CKM Unitarity Triangle.
Search for direct CP-violation in singly-Cabibbo suppressed D+- --> K+ K- pi+- decays
2013
We report on a search for direct CP asymmetry in the singly Cabibbo-suppressed decay D+- --> K+ K- pi+- using a data sample of 476 fb-1 accumulated with the BaBar detector running at and just below the Y(4S) resonance. The CP-violating decay rate asymmetry A_CP is determined to be (0.35 +- 0.30 +- 0.15)%. Model-dependent and model-independent Dalitz plot analysis techniques are used to search for CP-violating asymmetries in the various intermediate states.
