@misc{10481/95727, year = {2022}, month = {6}, url = {https://hdl.handle.net/10481/95727}, abstract = {search for decays of pair-produced neutral long-lived particles (LLPs) is presented using 139 fb−1 of proton-proton collision data collected by the ATLAS detector at the LHC in 2015–2018 at a centre-of-mass energy of 13TeV. Dedicated techniques were developed for the reconstruction of displaced jets produced by LLPs decaying hadronically in the ATLAS hadronic calorimeter. Two search regions are defined for different LLP kinematic regimes. The observed numbers of events are consistent with the expected background, and limits for several benchmark signals are determined. For a SM Higgs boson with a mass of 125 GeV, branching ratios above 10% are excluded at 95% confidence level for values of c times LLP mean proper lifetime in the range between 20mm and 10m depending on the model. Upper limits are also set on the cross-section times branching ratio for scalars with a mass of 60 GeV and for masses between 200 GeV and 1TeV.}, organization = {CERN}, organization = {Horizon 2020 and Marie Skłodowska-Curie Actions}, organization = {European Union}, organization = {La Caixa Banking Foundation}, organization = {CERCA Programme Generalitat de Catalunya and PROMETEO and GenT Programmes Generalitat Valenciana, Spain}, organization = {The Royal Society and Leverhulme Trust, United Kingdom}, organization = {BCKDF, CANARIE}, organization = {Aristeia programmes co-financed by EU-ESF and the Greek NSRF}, organization = {Norwegian Financial Mechanism 2014-2021}, organization = {MES of Russia and NRC KI, Russian Federation}, organization = {DOE and NSF, United States of America}, organization = {SNSF and Cantons of Bern and Geneva, Switzerland}, publisher = {SpringerLink}, keywords = {Hadron-Hadron Scattering}, title = {Search for neutral long-lived particles in pp collisions at √s = 13 TeV that decay into displaced hadronic jets in the ATLAS calorimeter}, doi = {10.1007/JHEP06(2022)005}, author = {Rodríguez Chala, Mikael and Atlas Collaboration, /}, }
