Comparison of the Z/γ ∗ + jets to γ + jets cross sections in pp collisions at √s = 8 TeV
A comparison of the differential cross sections for the processes Z/γ* + jets and photon (γ)+jets is presented. The measurements are based on data collected with the CMS detector at s=8(Formula presented.) TeV corresponding ...
Study of Z production in PbPb and pp collisions at root s(NN)=2.76 TeV in the dimuon and dielectron decay channels
The production of Z bosons is studied in the dimuon and dielectron decay channels in PbPb and pp collisions at (Formula presented.) TeV, using data collected by the CMS experiment at the LHC. The PbPb data sample corresponds ...
Measurement of the Z boson differential cross section in transverse momentum and rapidity in proton-proton collisions at 8 TeV
We present a measurement of the Z boson differential cross section in rapidity and transverse momentum using a data sample of pp collision events at a centre-of-mass energy s=8 TeV, corresponding to an integrated luminosity ...
Measurement of the cross section ratio σttbb/σttjj in pp collisions at √s=8 TeV
The first measurement of the cross section ratio σttbb/σttjj is presented using a data sample corresponding to an integrated luminosity of 19.6 fb-1 collected in pp collisions at √s = 8 TeV with the CMS detector at the ...
Angular coefficients of Z bosons produced in pp collisions at (root) S=8 TeV and decaying to μ+μ- as a function of transverse momentum and rapidity
Measurements of the five most significant angular coefficients, A0 through A4, for Z bosons produced in pp collisions at s=8 TeV and decaying to μ+μ- are presented as a function of the transverse momentum and rapidity of ...
Search for quark contact interactions and extra spatial dimensions using dijet angular distributions in proton-proton collisions at √s = 8 TeV
A search is presented for quark contact interactions and extra spatial dimensions in proton-proton collisions at √s=8 TeV using dijet angular distributions. The search is based on a data set corresponding to an integrated ...
