Measurement of B-c(2S)(+) and B-c*(2S)(+) cross section ratios in proton-proton collisions at root s=13 TeV
(Amer Physical Soc, 2020)
The ratios of the B-c (2S)(+) to B-c(+), B-c(*)(2S)(+) to B-c(+), and Bc(2S)(+) to Bco2STHORNthorn production cross sections are measured in proton-proton collisions at root s = 13 TeV, using a data sample collected by the ...
Search for dijet resonances using events with three jets in proton-proton collisions at root s=13 TeV
(Elsevier, 2020)
A search for a narrow resonance with a mass between 350 and 700 GeV, and decaying into a pair of jets, is performed using proton-proton collision events containing at least three jets. The data sample corresponds to an ...
The production of isolated photons in PbPb and pp collisions at root s(NN)=5.02 TeV
(Springer, 2020)
The transverse energy (ET gamma) spectra of photons isolated from other particles are measured using proton-proton (pp) and lead-lead (PbPb) collisions at the LHC at root s(NN) = 5.02 TeV with integrated luminosities of ...
Evidence for Top Quark Production in Nucleus-Nucleus Collisions
(Amer Physical Soc, 2020)
Ultrarelativistic heavy ion collisions recreate in the laboratory the thermodynamical conditions prevailing in the early universe up to 10(-6) sec, thereby allowing the study of the quark-gluon plasma (QGP), a state of ...
Observation of the Production of Three Massive Gauge Bosons at root s=13 TeV
(Amer Physical Soc, 2020)
The first observation is reported of the combined production of three massive gauge bosons (VVV with V = W, Z) in proton-proton collisions at a center-of-mass energy of 13 TeV. The analysis is based on a data sample recorded ...
Study of excited Lambda(0)(b) states decaying to Lambda(0)(b)pi(+)pi(-) in proton-proton collisions at root s=13TeV
(Elsevier, 2020)
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 ...
Development and validation of HERWIG 7 tunes from CMS underlying-event measurements
(Springer, 2021)
This paper presents new sets of parameters ("tunes") for the underlying-event model of the herwig 7 event generator. These parameters control the description of multiple-parton interactions (MPI) and colour reconnection ...
Search for physics beyond the standard model in events with jets and two same-sign or at least three charged leptons in proton-proton collisions at <mml:msqrt>s</mml:msqrt>=13 TeV
(Springer, 2020)
A data sample of events from proton-proton collisions with at least two jets, and two isolated same-sign or three or more charged leptons, is studied in a search for signatures of new physics phenomena. The data correspond ...
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 ...
W+ W- boson pair production in proton-proton collisions at root s=13 TeV
(Amer Physical Soc, 2020)
A measurement of the W+W- boson pair production cross section in proton-proton collisions at root s = 13 TeV is presented. The data used in this study are collected with the CMS detector at the CERN LHC and correspond to ...
