Search for Higgsino pair production in pp collisions at root s=13 TeV in final states with large missing transverse momentum and two Higgs bosons decaying via H -> b(b)over bar
(Amer Physical Soc, 2018)
Results are reported from a search for new physics in 13 TeV proton-proton collisions in the final state with large missing transverse momentum and two Higgs bosons decaying via H -> b(b)over bar. The search uses a data ...
Principal-component analysis of two-particle azimuthal correlations in PbPb and pPb collisions at CMS
(Amer Physical Soc, 2017)
For the first time a principle-component analysis is used to separate out different orthogonal modes of the two-particle correlation matrix from heavy ion collisions. The analysis uses data from root s(NN) = 2.76 TeV PbPb ...
Search for Evidence of the Type-III Seesaw Mechanism in Multilepton Final States in Proton-Proton Collisions at root s=13 TeV
(Amer Physical Soc, 2017)
A search for a signal consistent with the type-III seesaw mechanism in events with three or more electrons or muons is presented. The data sample consists of proton-proton collisions at root s = 13 TeV collected by the CMS ...
Bose-Einstein correlations in pp, pPb, and PbPb collisions at root s(NN)=0.9-7 TeV
(Amer Physical Soc, 2018)
Quantum-statistical (Bose-Einstein) two-particle correlations are measured in pp collisions at root s = 0.9, 2.76, and 7 TeV, as well as in pPb and peripheral PbPb collisions at nucleon-nucleon center-of-mass energies of ...
Measurement of associated Z plus charm production in proton-proton collisions at root s=8TeV
(Springer, 2018)
A study of the associated production of a Z boson and a charm quark jet (Z + c), and a comparison to production with a b quark jet (Z + b), in pp collisions at a centre-of-mass energy of 8 TeV are presented. The analysis ...
Study of the underlying event in top quark pair production in pp collisions at 13 TeV
(Springer, 2019)
Measurements of normalized differential cross sections as functions of the multiplicity and kinematic variables of charged-particle tracks from the underlying event in top quark and antiquark pair production are presented. ...
Search for top squarks and dark matter particles in opposite-charge dilepton final states at root s=13 TeV
(Amer Physical Soc, 2018)
A search for new physics is presented in final states with two oppositely charged leptons (electrons or muons), jets identified as originating from b quarks, and missing transverse momentum (p(T)(miss)). The search uses ...
Measurement of the weak mixing angle using the forward-backward asymmetry of Drell-Yan events in pp collisions at 8 TeV
(Springer, 2018)
A measurement is presented of the effective leptonic weak mixing angle (sin(2) theta(effl))using the forward- backward asymmetry of Drell-Yan lepton pairs (mu mu and ee) produced in proton-proton collisions at N root s = ...
Inclusive Search for a Highly Boosted Higgs Boson Decaying to a Bottom Quark-Antiquark Pair
(Amer Physical Soc, 2018)
An inclusive search for the standard model Higgs boson (H) produced with large transverse momentum (p(T)) and decaying to a bottom quark-antiquark pair (b (b) over bar) is performed using a data set of pp collisions at ...
Measurement of the Splitting Function in &ITpp &ITand Pb-Pb Collisions at root&ITsNN&IT=5.02 TeV
(Amer Physical Soc, 2018)
Data from heavy ion collisions suggest that the evolution of a parton shower is modified by interactions with the color charges in the dense partonic medium created in these collisions, but it is not known where in the ...
