Study of excited Λ0b states decaying to Λ0bπ+π−in proton-proton collisions at √s=13 TeV
(Elsevier, 2020-04-10)
A study of excited Lambda(0)(b) baryons is reported, based on a data sample collected in 2016-2018 with the CMS detector at the LHC in proton-proton collisions at a center-of-mass energy of 13 TeV, corresponding to an ...
Suppression of excited Υ states relative to the ground state in Pb-Pb collisions at √sNN =5.02 TeV
(American Physical Society, 2018-04-02)
The relative yields of gamma mesons produced in pp and Pb-Pb collisions at root s(NN) = 5.02 TeV and reconstructed via the dimuon decay channel are measured using data collected by the CMS experiment. Double ratios are ...
Search for a heavy Higgs boson decaying to a pair of W bosons in proton-proton collisions at s√ = 13 TeV
(Springer Nature, 2020-03-06)
A search for a heavy Higgs boson in the mass range from 0.2 to 3.0 TeV, decaying to a pair of W bosons, is presented. The analysis is based on proton-proton collisions at = 13 TeV recorded by the CMS experiment at the LHC ...
Search for dark matter produced in association with a single top quark or a top quark pair in proton-proton collisions at √s = 13 TeV
(Springer Nature, 2019-03-25)
A search for dark matter produced in association with top quarks in proton-proton collisions at a center-of-mass energy of 13 TeV is presented. The data set used corresponds to an integrated luminosity of 35.9 fb(-1) ...
Search for dark matter produced in association with a Higgs boson decaying to a pair of bottom quarks in proton–proton collisions at √s = 13 TeV
(Springer Nature, 2019-03-27)
A search for dark matter produced in association with a Higgs boson decaying to a pair of bottom quarks is performed in proton-proton collisions at a center-of-mass energy of 13 TeV collected with the CMS detector at the ...
Pileup mitigation at CMS in 13 TeV data
(IOP Publishing, 2020-09)
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 ...
Search for dark matter and unparticles in events with a Z boson and missing transverse momentum in proton-proton collisions at s√=13 TeV
(Springer International Publishing, 2017-03-10)
A search for dark matter and unparticle production at the LHC has been performed using events containing two charged leptons (electrons or muons), consistent with the decay of a Z boson, and large missing transverse momentum. ...
Searches for physics beyond the standard model with the MT2 variable in hadronic final states with and without disappearing tracks in proton–proton collisions at √s = 13 TeV
(Springer Nature, 2020-01-03)
Two related searches for phenomena beyond the standard model (BSM) are performed using events with hadronic jets and significant transverse momentum imbalance. The results are based on a sample of proton-proton collisions ...
Extraction and validation of a new set of CMS PYTHIA8 tunes from underlying-event measurements
(Springer Nature, 2020-01-03)
New sets of CMS underlying-event parameters ("tunes") are presented for the pythia8 event generator. These tunes use the NNPDF3.1 parton distribution functions (PDFs) at leading (LO), next-to-leading (NLO), or next-to-ne ...
Measurement of the top quark Yukawa coupling from t¯t kinematic distributions in the lepton + jets final state in proton-proton collisions at √ s = 13 TeV
(American Physical Society, 2019-10-17)
Results are presented for an extraction of the top quark Yukawa coupling from top quark-antiquark (t (t) over bar) kinematic distributions in the lepton plus jets final state in proton-proton collisions, based on data ...
