Measurement of the tt¯ production cross section in the all-jets final state in pp collisions at √s = 8 TeV
(2016-03-08)
The cross section for tt¯ production in the all-jets final state is measured in pp collisions at a centre-of-mass energy of 8 TeV at the LHC with the CMS detector, in data corresponding to an integrated luminosity of 18.4 ...
Measurement of top quark polarisation in t-channel single top quark production
(2016-04-13)
A first measurement of the top quark spin asymmetry, sensitive to the top
quark polarisation, in t-channel single top quark production is presented. It is based on a
sample of pp collisions at a centre-of-mass energy of ...
Search for W′ → tb in proton-proton collisions at √s = 8 TeV
(2016-02-18)
A search is performed for the production of a massive W′ boson decaying to a top and a bottom quark. The data analysed correspond to an integrated luminosity of 19.7 fb−1 collected with the CMS detector at the LHC in ...
Search for pair production of first and second generation leptoquarks in proton-proton collisions at √s = 8 TeV
(2016-02-24)
A search for pair production of first and second generation leptoquarks is performed in final states
containing either two charged leptons and two jets, or one charged lepton, one neutrino and two jets,
using proton-proton ...
Search for single production of scalar leptoquarks in proton-proton collisions at √s =8 TeV
(2016-02-24)
A search is presented for the production of both first- and second-generation scalar leptoquarks with a
final state of either two electrons and one jet or two muons and one jet. The search is based on a data sample
of ...
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 ...

(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. ...
