The measurement of differential cross section of a Z boson produced in association with jets is presented. The cross section is presented with respect to various jet kinematic variables where the Z bosons are reconstructed from opposite sign lepton pairs. The analysis is based on data of proton proton collisions with the centre of mass energy of 8 TeV collected in 2012 by the CMS experiment at LHC corresponding to 19.8 fb-1 of integrated luminosity. Obtained results are compared with different generators and are shown to be consistent with the Standard Model predictions.

Measurement of the differential cross sections for the associated production of a W boson and jets in proton-proton collisions at root s=13 TeV Sirunyan, A. M.; et. al. (2017-10-01) A measurement of the differential cross sections for a W boson produced in association with jets in the muon decay channel is presented. The measurement is based on 13 TeV proton-proton collision data corresponding to an integrated luminosity of 2.2 fb(-1), recorded by the CMS detector at the LHC. The cross sections are reported as functions of jet multiplicity, jet transverse momentum pT, jet rapidity, the scalar pT sum of the jets, and angular correlations between the muon and each jet for different jet m...
Differential cross section measurements for the production of a W boson in association with jets in proton-proton collisions at root s=7 TeV Khachatryan, V.; et. al. (Elsevier BV, 2015-02-01) Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (p(T)) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (H-T), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS d...
Measurement of electroweak production of a W boson and two forward jets in proton-proton collisions at root s=8 TeV Khachatryan, V.; et. al. (Springer Science and Business Media LLC, 2016-11-01) A measurement is presented of the cross section for the electroweak production of a W boson in association with two jets in proton-proton collisions at a center-of-mass energy of 8 TeV. The data set was collected with the CMS detector and corresponds to an integrated luminosity of 19.3 fb(- 1). The measured fiducial cross section for W bosons decaying to electrons or muons and for p(T)(j 1) > 60 GeV, p(T) (j 2) > 50 GeV, broken vertical bar eta(j)broken vertical bar 1000 GeV is 0.42 +/- 0.04 (stat) +/- 0: ...
Modification of jet shapes in PbPb collisions at root s(NN)=2.76 TeV Chatrchyan, S.; et. al. (Elsevier BV, 2014-03-01) The first measurement of jet shapes, defined as the fractional transverse momentum radial distribution, for inclusive jets produced in heavy-ion collisions is presented. Data samples of PbPb and pp collisions, corresponding to integrated luminosities of 150 mu b(-1) and 5.3 pb(-1) respectively, were collected at a nucleon-nucleon centre-of-mass energy of root s(NN) = 2.76 TeV with the CMS detector at the LHC. The jets are reconstructed with the anti-k(T) algorithm with a distance parameter R = 0.3, and the ...
