Measurement of the top quark pair production cross section in dilepton final states containing one τ lepton in pp collisions at s√ = 13 TeV
(Springer Nature, 2020-02-28)
The cross section of top quark pair production is measured in the t (t) over bar -> (lv(l))(tau(h)v(tau))b (b) over bar final state, where tau(h) refers to the hadronic decays of the tau lepton, and l is either an electron ...
Search for new physics in the multijet and missing transverse momentum final state in proton-proton collisions at root s=7 TeV
(American Physical Society, 2012-10-26)
A search for physics beyond the standard model is performed in events with at least three jets and large missing transverse momentum produced in proton-proton collisions at a center-of-mass energy of root s = 7 TeV. No ...
Tests of CMS hadron forward calorimeter upgrade readout box prototype
(IOP Publishing, 2012-10)
A readout box prototype for the CMS Hadron Forward calorimeter upgrade was built and tested in the CERN H2 beamline. The prototype was designed to enable simultaneous tests of different readout options for the four anode ...
Search for vector-like T and B quark pairs in final states with leptons at s√=13 TeV
(Springer Nature, 2018-08)
A search is presented for pair production of heavy vector-like T and B quarks in proton-proton collisions at s=13 TeV. The data sample corresponds to an integrated luminosity of 35.9 fb −1 , collected with the CMS detector ...
Constraining gluon distributions in nuclei using dijets in proton-proton and proton-lead collisions at √sNN = 5.02 TeV
(American Physical Society, 2018-08-07)
The pseudorapidity distributions of dijets as functions of their average transverse momentum (p(T)(ave)) are measured in proton-lead (pPb) and proton-proton (pp) collisions. The data samples were collected by the CMS ...
Experimental study of different silicon sensor options for the upgrade of the CMS Outer Tracker
(IOP Publishing, 2020-04)
During the high-luminosity phase of the LHC (HL-LHC), planned to start in 2027, the accelerator is expected to deliver an instantaneous peak luminosity of up to 7.5 x 10(34) cm(-2) s(-1). A total integrated luminosity of ...
Search for pair production of excited top quarks in the lepton plus jets final state
(Springer Science+Business Media, 2014-06)
A search is performed for pair-produced spin-3/2 excited top quarks , each decaying to a top quark and a gluon. The search uses data collected with the CMS detector from pp collisions at a center-of-mass energy of = 8 TeV, ...
Measurement of the weak mixing angle using the forward–backward asymmetry of Drell–Yan events in p p collisions at 8 TeV
(Springer Nature, 2018-09)
A measurement is presented of the effective leptonic weak mixing angle (sin2θeffℓ) using the forward–backward asymmetry of Drell–Yan lepton pairs (μμ and e e) produced in proton–proton collisions at s=8TeV at the CMS ...
Measurement of the groomed jet mass in PbPb and pp collisions at √sNN=5.02 TeV
(Springer Nature, 2018-10)
A measurement of the groomed jet mass in PbPb and pp collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV with the CMS detector at the LHC is presented. Jet grooming is a recursive procedure which sequentially ...
Observation of higgs boson decay to bottom quarks
(American Physical Society, 2018-09-17)
The observation of the standard model (SM) Higgs boson decay to a pair of bottom quarks is presented. The main contribution to this result is from processes in which Higgs bosons arc produced in association with a W or Z ...
