Angular Analysis Of The Decay B+ -> K+Mu(+)Mu(-) In Proton-Proton Collisions At Root S=8 Tev
(Amer Physical Soc, 2018)
The angular distribution of the flavor-changing neutral current decay B+ -> K+mu(+)mu(-) is studied in proton-proton collisions at a center-of-mass energy of 8 TeV. The analysis is based on data collected with the CMS ...
Search for Black Holes and Sphalerons in High-Multiplicity Final States in Proton-Proton Collisions A Root S=13 Tevt
(Springer, 2018)
A search in energetic, high-multiplicity final states for evidence of physics beyond the standard model, such as black holes, string balls, and electroweak sphalerons, is presented. The data sample corresponds to an ...
Search for Beyond the Standard Model Higgs Bosons Decaying Into A B(B)Over-Bar Pair in Pp Collisions At Root S=13 Tev
(Springer, 2018)
A search for Higgs bosons that decay into a bottom quark-antiquark pair and are accompanied by at least one additional bottom quark is performed with the CMS detector. The data analyzed were recorded in proton-proton ...
Search for the Decay of A Higgs Boson in the Ll Gamma Channel in Proton-Proton Collisions At Root S=13 Tev
(Springer, 2018)
A search for a Higgs boson decaying into a pair of electrons or muons and a photon is described. Higgs boson decays to a Z boson and a photon (H Z , = e or ), or to two photons, one of which has an internal conversion into ...
Suppression of Excited Gamma States Relative to the Ground State in Pb-Pb Collisions at Root S(Nn)=5.02 Tev
(Amer Physical Soc, 2018)
The relative yields of gamma mesons produced in pp and Pb-Pb collisions at root s(NN) = 5.02 TeV and reconstructed via the dimuon decay channel are measured using data collected by the CMS experiment. Double ratios are ...
