Event activity dependence of Υ(nS) production in √SNN = 5.02 TeV pPb and √s = 2.76 TeV pp collisions
(2014-04-15)
The production of Y (1S), Y (2S), and Y (3S) is investigated in pPb and pp collisions at centre-of-mass energies per nucleon pair of 5.02 TeV and 2.76 TeV, respectively. The datasets correspond to integrated luminosities ...
Search for electroweak production of charginos and neutralinos using leptonic final states in pp collisions at √s = 7 TeV
(2012-11-27)
The 2011 dataset of the CMS experiment, consisting of an integrated luminosity of 4.98 fb−1 of pp collisions at √s = 7 TeV, enables expanded searches for direct electroweak pair production of charginos and neutralinos ...
Search for baryon number violation in top-quark decays
(2014-04-04)
A search for baryon number violation (BNV) in top-quark decays is performed using pp collisions
produced by the LHC at √s = 8 TeV. The top-quark decay considered in this search results in one
light lepton (muon or ...
Long-range two-particle correlations of strange hadrons with charged particles in pPb and PbPb collisions at LHC energies
(2015-03-06)
Measurements of two-particle angular correlations between an identified strange hadron (K0
S or Λ/Λ)
and a charged particle, emitted in pPb collisions, are presented over a wide range in pseudorapidity
and full azimuth. ...
Search for the standard model Higgs boson produced in association with a top-quark pair in pp collisions at the LHC
(2013-05-28)
A search for the standard model Higgs boson produced in association with a top-quark pair is presented using data samples corresponding to an integrated luminosity of 5.0 fb−1 (5.1 fb−1) collected in pp collisions at the ...
Search for heavy bottom-like quarks in 4.9 fb-1 of pp collisions at √s = 7 TeV
(2012-05-25)
Results are presented from a search for heavy bottom-like quarks, pair-produced in pp collisions at √s = 7 TeV, undertaken with the CMS experiment at the LHC. The b′ quarks are assumed to decay exclusively to tW. The ...
Measurement of transverse momentum relative to dijet systems in PbPb and pp collisions at √sNN = 2.76 TeV
(2016-01-04)
An analysis of dijet events in PbPb and pp collisions is performed to explore the
properties of energy loss by partons traveling in a quark-gluon plasma. Data are collected
at a nucleon-nucleon center-of-mass energy of ...
Measurement of the triple-differential cross section for photon + jets production in proton-proton collisions at √s = 7 TeV
(2014-06-03)
A measurement of the triple-differential cross section, d3σ/(dpγTdηγdηjet), in photon + jets final states using a data sample from proton-proton collisions at √s = 7 TeV is presented. This sample corresponds to an integrated ...
Search for new physics in events with same-sign dileptons and b jets in pp collisions at √s = 8 TeV
(2013-03-06)
A search for new physics is performed using events with isolated same-sign leptons and at least two bottom-quark jets in the final state. Results are based on a sample of proton-proton collisions collected at a center-of-mass ...
Measurement of the ratio B(Bs0→J/ψf0(980))/B(Bs0→J/ψϕ(1020)) in pp collisions at √s=7 TeV
(2016-05-10)
A measurement of the ratio of the branching fractions of the B0
s meson to J/ψf0(980) and to J/ψφ(1020)
is presented. The J/ψ, f0(980), and φ(1020) are observed through their decays to μ+μ−, π+π−, and
K+K−, respectively. ...
