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 ...
Search for the production of an excited bottom quark decaying to tW in proton-proton collisions at √s = 8 TeV
(2016-01-27)
A search is presented for a singly produced excited bottom quark (b∗) decaying
to a top quark and a W boson in the all-hadronic, lepton+jets, and dilepton final states
in proton-proton collisions at √s = 8 TeV recorded ...
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. ...
Search for the associated production of the Higgs boson with a top-quark pair
(2014-09-14)
A search for the standard model Higgs boson produced in association with a top-quark pair (tt¯H) is presented, using data samples corresponding to integrated luminosities of up to 5.1 fb−1 and 19.7 fb−1 collected in pp ...
Search for new physics in events with same-sign dileptons and jets in pp collisions at √s = 8 TeV
(2014-01-29)
A search for new physics is performed based on events with jets and a pair of isolated, same-sign leptons. The results are obtained using a sample of proton-proton collision data collected by the CMS experiment at a ...
Angular coefficients of Z bosons produced in pp collisions at √s=8 TeV and decaying to μ+μ- as a function of transverse momentum and rapidity
(2015-11-15)
Measurements of the five most significant angular coefficients, A0 through A4, for Z bosons produced in pp collisions at √s=8 TeV and decaying to μ+μ- are presented as a function of the transverse momentum and rapidity of ...
