Modification of jet shapes in PbPb collisions at √sNN=2.76TeV
(2014-03-07)
The first measurement of jet shapes, defined as the fractional transverse momentum radial distribution, for inclusive jets produced in heavy-ion collisions is presented. Data samples of PbPb and pp collisions, corresponding ...
Search for pair production of excited top quarks in the lepton + jets final state
(2014-06-19)
A search is performed for pair-produced spin-3/2 excited top quarks (t∗t¯∗), 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 ...
Evidence for the 125 gev higgs boson decaying to a pair of τ leptons
(2014-05)
A search for a standard model Higgs boson decaying into a pair of τ leptons is performed using events recorded by the CMS experiment at the LHC in 2011 and 2012. The dataset corresponds to an integrated luminosity of 4.9 ...
Event activity dependence of υ(nS) production in √SNN = 5.02 TeV pPb and √s = 2.76 TeV pp collisions

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 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 ...
Measurement of the triple-differential cross section for photon + jets production in proton-proton collisions at √s = 7 TeV
