Pileup mitigation at CMS in 13 TeV data
(Iop Publishing Ltd, 2020)
With increasing instantaneous luminosity at the LHC come additional reconstruction challenges. At high luminosity, many collisions occur simultaneously within one proton-proton bunch crossing. The isolation of an interesting ...
Inclusive search for highly boosted Higgs bosons decaying to bottom quark-antiquark pairs in proton-proton collisions at <mml:msqrt>s</mml:msqrt>=13 TeV
A search for standard model Higgs bosons (H) produced with transverse momentum (p(T)) greater than 450 GeV and decaying to bottom quark-antiquark pairs (bb<overbar></mml:mover>) is performed using proton-proton collision ...
Observation of electroweak production of W gamma with two jets in proton-proton collisions at root s=13 TeV
A first observation is presented for the electroweak production of a W boson, a photon, and two jets in proton-proton collisions. The W boson decays are selected by requiring one identified electron or muon and an imbalance ...
Study of J/psi meson production inside jets in pp collisions at N root s=8 TeV The CM Collaboration
A study of the production of prompt J/psi mesons contained in jets in proton-proton collisions at root s = 8 TeV is presented. The analysis is based on data corresponding to an integrated luminosity of 19.1 fb(-1) collected ...
Study of dijet events with a large rapidity gap between the two leading jets in pp collisions at root s = 7TeV (vol 78, 242, 2018)
Events with no charged particles produced between the two leading jets are studied in proton-proton collisions at
A multi-dimensional search for new heavy resonances decaying to boosted WW, WZ, or ZZ boson pairs in the dijet final state at 13TeV
A search in an all-jet final state for new massive resonances decaying to WW, WZ, or ZZ boson pairs using a novel analysis method is presented. The analysis is performed on data corresponding to an integrated luminosity ...
Search for supersymmetry in pp collisions at root s=13 TeV with 137 fb(-1) in final states with a single lepton using the sum of masses of large-radius jets
(Amer Physical Soc, 2020)
Results are reported from a search for new physics beyond the standard model in proton-proton collisions in final states with a single lepton; multiple jets, including at least one jet tagged as originating from the ...
Search for direct pair production of supersymmetric partners to the tau lepton in proton-proton collisions at root s=13TeV
A search is presented for t slepton pairs produced in proton-proton collisions at a center-of-mass energy of 13 TeV. The search is carried out in events containing two t leptons in the final state, on the assumption that ...
Observation of the Lambda(0)(b) -> J/psi Lambda phi decay in proton-proton collisions at root s=13 TeV
The observation of the Lambda(0)(b) -> J/psi Lambda phi decay is reported using proton-proton collision data collected at root s = 13TeV by the CMS experiment at the LHC in 2018, corresponding to an integrated luminosity ...
Measurement of B-s(0) meson production in pp and PbPb collisions at root S-NN=5.02 TeV
The production cross sections of B-s(0) mesons and charge conjugates are measured in proton-proton (pp) and PbPb collisions via the exclusive decay channel B-s(0)-> J/ psi phi ->mu(+) mu(-) K+K- at a center-of-mass energy ...
