This results in an event topology where one of the jets can be aligned with the direction of the missing transverse momentum. The first search for semi-visible jets produced via a $t$-channel mediator exchange is presented. The analysis uses proton-proton collisions with an integrated luminosity of 139 fb$^{-1}$ and a centre-of-mass energy of 13 TeV, collected with the ATLAS detector during the Run 2 of the LHC. No excess over Standard Model predictions is observed. Assuming a coupling strength of unity between the mediator, a Standard Model quark and a dark quark, mediator masses up to 2.7 TeV are excluded at the 95% confidence level.

The search for events with this \"disappearing track\" signature is performed in a sample of proton-proton collisions recorded by the CMS experiment at the LHC with a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 101 fb$^{-1}$ recorded in 2017 and 2018.

Such particles can produce events with an isolated track that is missing hits in the outermost layers of the silicon tracker, and is also associated with little energy deposited in the calorimeters and no hits in the muon detectors. The search for events with this \"disappearing track\" signature is performed in a sample of proton-proton collisions recorded by the CMS experiment at the LHC with a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of $101\\text{fb}^{-1}$ recorded in 2017 and 2018.

The analysis uses 139 fb$^{-1}$ of proton$-$proton collision data at $\\sqrt{s} = 13$ TeV collected by the ATLAS experiment at the Large Hadron Collider between 2015 and 2018. The selection rejects events containing isolated electrons or muons, and makes requirements according to the number of $b$-tagged jets and the scalar sum of masses of large-radius jets. The search extends previous analyses both in using a larger dataset and by employing improved jet and missing transverse momentum reconstruction methods which more cleanly separate signal from background processes. No evidence for physics beyond the Standard Model is found. The results are interpreted in the context of supersymmetry-inspired simplified models, significantly extending the limits on the gluino mass in those models. In particular, limits on the gluino mass are set at 2 TeV when the lightest neutralino is nearly massless in a model assuming a two-step cascade decay via the lightest chargino and second-lightest neutralino.","access_urls":{"links":{"csv":"https://www.hepdata.net/download/submission/ins1811596/1/csv","json":"https://www.hepdata.net/download/submission/ins1811596/1/json","root":"https://www.hepdata.net/download/submission/ins1811596/1/root","yaml":"https://www.hepdata.net/download/submission/ins1811596/1/yaml","yoda":"https://www.hepdata.net/download/submission/ins1811596/1/yoda","yoda-h5":"https://www.hepdata.net/download/submission/ins1811596/1/yoda.h5"}},"analyses":[{"analysis":"https://www.hepdata.net/record/resource/1978652?landing_page=true","filename":"ANA-SUSY-2018-17.cxx","type":"SimpleAnalysis"},{"analysis":"https://doi.org/10.14428/DVN/I2CZWU","type":"MadAnalysis"}],"arxiv_id":"arXiv:2008.06032","authors":["Aad, Georges","Abbott, Brad","Abbott, Dale Charles","Abed Abud, Adam","Abeling, Kira","Abhayasinghe, Deshan Kavishka","Abidi, Syed Haider","Abouzeid, Ossama","Abraham, Nicola","Abramowicz, Halina"],"collaborations":["ATLAS"],"control_number":"93733","creation_date":"2020-08-13","data":[],"data_abstract":null,"data_keywords":{"cmenergies":[{"gte":13000.0,"lte":13000.0}],"observables":["ACC","CLS","EFF","N","$\\mathcal{S}(E_{\\mathrm{T}}^{\\mathrm{miss}})$"],"phrases":["multijets","Supersymmetry","RPC","SUSY","Gluino pair production","RPV"],"reactions":["two-step","P P --> GLUINO GLUINO","PP --> GLUINO GLUINO X"]},"date":"13 Aug 2020","doc_type":"publication","doi":"10.1007/JHEP10(2020)062","first_author":{"affiliation":"Marseille, CPPM","full_name":"Aad, Georges"},"hepdata_doi":"10.17182/hepdata.93733","id":93733,"inspire_id":"1811596","journal_info":"JHEP 10 (2020) 062","keywords":[{"source":"author","value":"Hadron-Hadron scattering (experiments)"},{"schema":"INSPIRE","value":"p p: scattering"},{"schema":"INSPIRE","value":"p p: colliding beams"},{"schema":"INSPIRE","value":"jet: multiple production"},{"schema":"INSPIRE","value":"transverse momentum: missing-energy"},{"schema":"INSPIRE","value":"gluino: pair production"},{"schema":"INSPIRE","value":"gluino: mass: lower limit"},{"schema":"INSPIRE","value":"final state: ((n)jet)"},{"schema":"INSPIRE","value":"jet: bottom"},{"schema":"INSPIRE","value":"bottom: particle identification"},{"schema":"INSPIRE","value":"jet: multiplicity"},{"schema":"INSPIRE","value":"CERN LHC Coll"},{"schema":"INSPIRE","value":"neutralino: massless"},{"schema":"INSPIRE","value":"ATLAS"},{"schema":"INSPIRE","value":"R parity: invariance"},{"schema":"INSPIRE","value":"supersymmetry: parameter space"},{"schema":"INSPIRE","value":"cascade decay"},{"schema":"INSPIRE","value":"new particle"},{"schema":"INSPIRE","value":"new physics: search for"},{"schema":"INSPIRE","value":"background"},{"schema":"INSPIRE","value":"electron"},{"schema":"INSPIRE","value":"chargino"},{"schema":"INSPIRE","value":"muon"},{"schema":"INSPIRE","value":"channel cross section: upper limit"},{"schema":"INSPIRE","value":"experimental results"},{"schema":"INSPIRE","value":"13000 GeV-cms"},{"schema":"PDG","value":"S046GNO"},{"schema":"PDG","value":"S046GNV"}],"last_updated":"2021-03-01T14:51:24","parent_child_join":{"name":"parent_publication"},"publication_date":"2020-10-17T00:00:00","recid":93733,"resources":[{"description":"Webpage with all figures and tables including auxiliary material.","type":"html","url":"https://atlas.web.cern.ch/Atlas/GROUPS/PHYSICS/PAPERS/SUSY-2018-17/"},{"description":"Turht level code that computes acceptances for the signal regions using the SimpleAnalysis framework.","type":"SimpleAnalysis","url":"https://www.hepdata.net/record/resource/1978652?landing_page=true"},{"description":"SLHA files for a single point in each of the signal models (gluino decay through two-step cascade, gluino decay via RPV coupling and gluino decay to off-shell top quarks and the LSP).","type":"gz","url":"https://www.hepdata.net/record/resource/1978653?landing_page=true"},{"description":"MadAnalysis 5 analysis","type":"MadAnalysis","url":"https://doi.org/10.14428/DVN/I2CZWU"}],"subject_area":["hep-ex"],"summary_authors":[{"affiliation":"Marseille, CPPM","full_name":"Aad, Georges"},{"affiliation":"Oklahoma U.","full_name":"Abbott, Brad"},{"affiliation":"Massachusetts U., Amherst","full_name":"Abbott, Dale Charles"},{"affiliation":"CERN","full_name":"Abed Abud, Adam"},{"affiliation":"Gottingen U., II.
