Measurement of quark- and gluon-like jet fractions using jet charge in PbPb and pp collisions at 5.02 TeV
(Springer Nature, 2020-07-17)
The momentum-weighted sum of the electric charges of particles inside a jet, known as jet charge, is sensitive to the electric charge of the particle initiating the parton shower. This paper presents jet charge distributions ...
Search for supersymmetry in proton-proton collisions at √s = 13 TeV in events with high-momentum Z bosons and missing transverse momentum
(Springer Nature, 2020-09-23)
A search for new physics in events with two highly Lorentz-boosted Z bosons and large missing transverse momentum is presented. The analyzed proton-proton collision data, corresponding to an integrated luminosity of 137 ...
Search for new neutral Higgs bosons through the H→ZA→ℓ+ℓ−bb¯¯¯ process in pp collisions at s√ = 13 TeV
(Springer Nature, 2020-03-10)
This paper reports on a search for an extension to the scalar sector of the standard model, where a new CP-even (odd) boson decays to a Z boson and a lighter CP-odd (even) boson, and the latter further decays to a b quark ...
Measurement of the semileptonic t t ¯ + γ production cross section in pp collisions at √s=8 TeV
(Springer International Publishing, 2017-10-02)
A measurement of the cross section for top quark-antiquark ( tt¯tt¯ ) pairs produced in association with a photon in proton-proton collisions at s√=8s=8 TeV is presented. The analysis uses data collected with the CMS ...
Measurement of the Z boson differential production cross section using its invisible decay mode (Z → νν¯) in proton-proton collisions at √s = 13 TeV
(Springer, 2021-05-21)
Measurements of the total and differential fiducial cross sections for the Z boson decaying into two neutrinos are presented at the LHC in proton-proton collisions at a center-of-mass energy of 13 TeV. The data were collected ...
Measurements of Higgs boson production cross sections and couplings in the diphoton decay channel at s√ = 13 TeV
(Springer, 2021-07-07)
Measurements of Higgs boson production cross sections and couplings in events where the Higgs boson decays into a pair of photons are reported. Events are selected from a sample of proton-proton collisions at s = 13 TeV ...
Search for nonresonant Higgs boson pair production in final states with two bottom quarks and two photons in proton-proton collisions at s√ = 13 TeV
(Springer, 2021-03-29)
A search for nonresonant production of Higgs boson pairs via gluon-gluon and vector boson fusion processes in final states with two bottom quarks and two photons is presented. The search uses data from proton-proton ...
Search for new physics in top quark production with additional leptons in proton-proton collisions at s√ = 13 TeV using effective field theory
(Springer, 2021-03-09)
Events containing one or more top quarks produced with additional prompt leptons are used to search for new physics within the framework of an effective field theory (EFT). The data correspond to an integrated luminosity ...
In-medium modification of dijets in PbPb collisions at √sNN = 5.02 TeV
(Springer, 2021-05-14)
Modifications to the distribution of charged particles with respect to high transverse momentum (pT) jets passing through a quark-gluon plasma are explored using the CMS detector. Back-to-back dijets are analyzed in lead-lead ...
Measurement of differential cross sections for Z bosons produced in association with charm jets in pp collisions at √s = 13 TeV
(Springer, 2021-04-13)
Measurements are presented of differential cross sections for the production of Z bosons in association with at least one jet initiated by a charm quark in pp collisions at s√
= 13 TeV. The data recorded by the CMS ...
