Search for leptophobic Z bosons decaying into four-lepton final states in proton-proton collisions at root s=8 TeV
(Physics Letters B, 2017)
A search for heavy narrow resonances decaying into four-lepton final states has been performed using proton-proton collision data at root s= 8 TeVcollected by the CMS experiment, corresponding to an integrated luminosity ...
Evidence for collectivity in pp collisions at the LHC
(Physics Letters B, 2017)
Measurements of two- and multi-particle angular correlations in pp collisions at root s = 5, 7, and 13TeV are presented as a function of charged-particle multiplicity. The data, corresponding to integrated luminosities of ...
Search for single production of vector-like quarks decaying into a b quark and a W boson in proton-proton collisions at root s=13 TeV
(Physics Letters B, 2017)
A search is presented for a heavy vector-like quark, decaying into a b quark and a W boson, which is produced singly in association with a light flavor quark and a b quark. The analysis is performed using a data sample of ...
Search for a Higgs boson decaying into gamma*gamma - GT ll gamma with low dilepton mass in pp collisions at root s=8 TeV
(Physics Letters B, 2016)
A search is described for a Higgs boson decaying into two photons, one of which has an internal conversion to a muon or an electron pair (ll gamma). The analysis is performed using proton-proton collision data recorded ...
Performance of the CMS ECAL safety system for super modules SM0 and SM1
(Nuclear Instruments and Methods in Physics Research. Section A: Accelerators, Spectrometers, Detectors, and Associated Equipment, 2005)
A prototype of the safety system for the electromagnetic calorimeter (ECAL) of the CMS detector at LHC has been implemented and tested in Super Modules SM0 and SM1 during the ECAL test-beam campaign in summer 2003. The aim ...
Upsilon (nS) polarizations versus particle multiplicity in pp collisions at root s=7 TeV
(Physics Letters B, 2016)
The polarizations of the Upsilon(1S), Upsilon(2S), and Upsilon(3S) mesons are measured as a function of the charged particle multiplicity in proton-proton collisions at root s = 7 TeV. The measurements are performed with ...
