Search for tri-nucleon decays of$$^{76}$$ Ge in GERDA
We search for tri-nucleon decays of$$^{76}$$76 Ge in the dataset from the GERmanium Detector Array (GERDA) experiment. Decays that populate excited levels of the daughter nucleus above the threshold for particle emission lead to disintegration and are not considered. The ppp-, ppn-, and pnn-decays lead to$$^{73}$$73 Cu,$$^{73}$$73 Zn, and$$^{73}$$73 Ga nuclei, respectively. These nuclei are unstable and eventually proceed by the beta decay of$$^{73}$$73 Ga to$$^{73}$$73 Ge (stable). We search for the$$^{73}$$73 Ga decay exploiting the fact that it dominantly populates the 66.7 keV$$^{73m}$$73 m Ga state with half-life of 0.5 s. The nnn-decays of$$^{76}$$76 Ge that proceed via$$^{73m}$$73 m Ge are also included in our analysis. We find no signal candidate and place a limit on the sum of the decay widths of the inclusive tri-nucleon decays that corresponds to a lower lifetime limit of 1.2$$\\times $$× 10$$^{26}$$26 yr (90% credible interval). This result improves previous limits for tri-nucleon decays by one to three orders of magnitude.

Search for leptoquark pair production decaying into Formula omitted or Formula omitted in multi-lepton final states in pp collisions at Formula omitted with the ATLAS detector
A search for leptoquark pair production decaying into [Formula omitted] or [Formula omitted] in final states with multiple leptons is presented. The search is based on a dataset of pp collisions at [Formula omitted] recorded with the ATLAS detector during Run 2 of the Large Hadron Collider, corresponding to an integrated luminosity of 139 fb [Formula omitted]. Four signal regions, with the requirement of at least three light leptons (electron or muon) and at least two jets out of which at least one jet is identified as coming from a b-hadron, are considered based on the number of leptons of a given flavour. The main background processes are estimated using dedicated control regions in a simultaneous fit with the signal regions to data. No excess above the Standard Model background prediction is observed and 95% confidence level limits on the production cross section times branching ratio are derived as a function of the leptoquark mass. Under the assumption of exclusive decays into [Formula omitted] ( [Formula omitted]), the corresponding lower limit on the scalar mixed-generation leptoquark mass [Formula omitted] is at 1.58 (1.59) TeV and on the vector leptoquark mass [Formula omitted] at 1.67 (1.67) TeV in the minimal coupling scenario and at 1.95 (1.95) TeV in the Yang-Mills scenario.

Search for top-philic heavy resonances in pp collisions at Formula omitted Formula omitted with the ATLAS detector
A search for the associated production of a heavy resonance with a top-quark or a top-antitop-quark pair, and decaying into a [Formula omitted] pair is presented. The search uses the data recorded by the ATLAS detector in pp collisions at [Formula omitted] [Formula omitted] at the Large Hadron Collider during the years 2015-2018, corresponding to an integrated luminosity of 139 [Formula omitted]. Events containing exactly one electron or muon are selected. The two hadronically decaying top quarks from the resonance decay are reconstructed using jets clustered with a large radius parameter of [Formula omitted]. The invariant mass spectrum of the two top quark candidates is used to search for a resonance signal in the range of 1.0 [Formula omitted] to 3.2 [Formula omitted]. The presence of a signal is examined using an approach with minimal model dependence followed by a model-dependent interpretation. No significant excess is observed over the background expectation. Upper limits on the production cross section times branching ratio at 95% confidence level are provided for a heavy [Formula omitted] boson based on a simplified model, for [Formula omitted] mass between 1.0 [Formula omitted] and 3.0 [Formula omitted]. The observed (expected) limits range from 21 (14) fb to 119 (86) fb depending on the choice of model parameters.

Measurement of the Formula omitted and Formula omitted cross-sections in pp collisions at Formula omitted TeV with the ATLAS detector
The inclusive Higgs boson production cross-section is measured in the di-photon and the [Formula omitted] decay channels using 31.4 and 29.0 fb [Formula omitted] of pp collision data respectively, collected with the ATLAS detector at a centre-of-mass energy of [Formula omitted] [Formula omitted]. To reduce the model dependence, the measurement in each channel is restricted to a particle-level phase space that closely matches the channel's detector-level kinematic selection, and it is corrected for detector effects. These measured fiducial cross-sections are [Formula omitted] [Formula omitted] fb, and [Formula omitted] [Formula omitted] fb, in agreement with the corresponding Standard Model predictions of [Formula omitted] fb and [Formula omitted] fb. Assuming Standard Model acceptances and branching fractions for the two channels, the fiducial measurements are extrapolated to the full phase space yielding total cross-sections of [Formula omitted] pb and [Formula omitted] pb at 13.6 [Formula omitted] from the di-photon and [Formula omitted] measurements respectively. The two measurements are combined into a total cross-section measurement of [Formula omitted] pb, to be compared with the Standard Model prediction of [Formula omitted] pb.
