The multiplicity distributions of the high frequency gravitons / Giovannini, Massimo (CERN ; INFN, Milan Bicocca)
When the gravitons are created thanks to the variation of the space-time curvature the multiplicity distributions quantify the probability of producing a given number of species around the average occupation numbers of the underlying multiparticle states. [...]

Precision measurement of the ${\it{\Xi}}_b^0$ baryon lifetime / LHCb Collaboration
A sample of $pp$ collision data, corresponding to an integrated luminosity of 5.4 fb$^{-1}$ and collected by the LHCb experiment during LHC Run 2, is used to measure the ratio of the lifetime of the ${\it{\Xi}}_b^0$ baryon to that of the ${\it{\Lambda}}_b^0$ baryon, $r_{\tau}\equiv\tau_{{\it{\Xi}}_b^0}/\tau_{{\it{\Lambda}}_b^0}$.

Search for lepton flavor violation at ATLAS and CMS / Basile, Chiara (INFN, Rome ; Rome U.) /ATLAS and CMS Collaborations
This contribution describes a selection of recent Charged Lepton Flavor Violation searches performed by the ATLAS and CMS collaborations at the Large Hadron Collider (LHC), covering a wide range of sectors including rare tau decays, top-quark interactions, Higgs boson decays, and heavy resonance searches. All the results in this document exploit the full proton-proton collision dataset collected during the LHC Run2 corresponding to and integrated luminosity of approximately 138~fb$^{-1}$..

Search for the Higgs boson decay to a $Z$ boson and a photon in $pp$ collisions at $\sqrt{s}=13$ TeV and $13.6$ TeV with the ATLAS detector
A search for the Higgs boson decay to a $Z$ boson and a photon in the $\ell\ell\gamma$ ($\ell = e, \mu$) final state is performed using $pp$ collisions at $\sqrt{s}=13.6$ TeV recorded with the ATLAS detector at the Large Hadron Collider during 2022-2024, corresponding to an integrated luminosity of 165 fb$^{-1}$.
