Measurement of top quark polarisation in t-channel single top quark production
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 ...
Measurement of transverse momentum relative to dijet systems in PbPb and pp collisions at √sNN = 2.76 TeV
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 excited leptons in proton-proton collisions at √s = 8 TeV
A search for compositeness of electrons and muons is presented using a data sample of proton-proton collisions at a center-of-mass energy of (Formula presented.) TeV collected with the CMS detector at the LHC and corresponding ...
Correlations between jets and charged particles in PbPb and pp collisions at sNN=2.76 TeV
The quark-gluon plasma is studied via medium-induced changes to correlations between jets and charged particles in PbPb collisions compared to pp reference data. This analysis uses data sets from PbPb and pp collisions ...
Search for a very light NMSSM Higgs boson produced in decays of the 125 GeV scalar boson and decaying into τ leptons in pp collisions at √s=8 TeV
A search for a very light Higgs boson decaying into a pair of τ leptons is presented within the framework of the next-to-minimal supersymmetric standard model. This search is based on a data set corresponding to an ...
Search for anomalous single top quark production in association with a photon in pp collisions at √s = 8 TeV
The result of a search for flavor changing neutral currents (FCNC) through single top quark production in association with a photon is presented. The study is based on proton-proton collisions at a center-of-mass energy ...
