Observation of Medium-Induced Modifications of Jet Fragmentation in Pb-Pb Collisions at √s[subscript NN] = 5.02 TeV Using Isolated Photon-Tagged Jets
(American Physical Society, 2018-12)
Measurements of fragmentation functions for jets associated with an isolated photon are presented for the first time in pp and Pb-Pb collisions. The analysis uses data collected with the CMS detector at the CERN LHC at a ...
Search for supersymmetry in events with photons and missing transverse energy in pp collisions at 13 TeV
(Elsevier, 2017-04)
The results of a search for new physics in final states with photons and missing transverse energy are reported. The study is based on a sample of proton–proton collisions collected at a center-of-mass energy of 13 TeV ...
Search for the Pair Production of Third-Generation Squarks with Two-Body Decays to a Bottom or Charm Quark and a Neutralino in Proton–proton Collisions at √s = 13 TeV
(Elsevier, 2018-01)
Results are presented from a search for the pair production of third-generation squarks in proton–proton collision events with two-body decays to bottom or charm quarks and a neutralino, which produces a significant imbalance ...
Search for Single Production of a Vector-Like T Quark Decaying to a Z Boson and a Top Quark in Proton–proton Collisions at √s = 13 TeV
(Elsevier, 2018-04)
A search is presented for single production of a vector-like quark (T) decaying to a Z boson and a top quark, with the Z boson decaying leptonically and the top quark decaying hadronically. The search uses data collected ...
Search for single production of vector-like quarks decaying to a Z boson and a top or a bottom quark in proton-proton collisions at s=13$$ \sqrt{s}=13 $$ TeV
(Springer Nature, 2017-05)
A search for single production of vector-like quarks, T and B, decaying into a Z boson and a top or a bottom quark, respectively, is presented. The search is performed using data collected by the CMS experiment at the LHC ...
Search for New Phenomena with Multiple Charged Leptons in Proton–proton Collisions at √s = 13 TeV
(Springer Berlin Heidelberg, 2017-09)
Results are reported from a search for physics beyond the standard model in final states with at least three charged leptons, in any combination of electrons or muons. The data sample corresponds to an integrated luminosity ...
Search for Top Quark Decays via Higgs-Boson-Mediated Flavor-Changing Neutral Currents in Pp Collisions at √s = 8 TeV
(Springer Nature, 2017-07)
A search is performed for Higgs-boson-mediated flavor-changing neutral currents in the decays of top quarks. The search is based on proton-proton collision data corresponding to an integrated luminosity of 19.7 fb⁻¹ at a ...
Mechanical stability of the CMS strip tracker measured with a laser alignment system
(IOP Publishing, 2017-04)
The CMS tracker consists of 206 m 2 of silicon strip sensors assembled on carbon fibre composite structures and is designed for operation in the temperature range from -25 to +25°C. The mechanical stability of tracker ...
