Abstract

Measurements of the jet and vector boson in association with jets production, extraction of<i>α<sub>s</sub></i>and PDF constraints at CMS

Highlights

CMS has performed a wide range of studies of Standard Model physics using data collected at a center of mass energy of 7 and 8 TeV from 2010 to 2012
The production of Z and W bosons, which may be identified through their leptonic decays, is theoretically well described within the framework of the Standard Model
The measured jet cross section is corrected for detector effects and compared to predictions of perturbative QCD at next-to-leading order using various sets of parton distribution functions

Summary

Introduction

CMS has performed a wide range of studies of Standard Model physics using data collected at a center of mass energy of 7 and 8 TeV from 2010 to 2012 .Jets production is the most common process in a hadron collider and cross section measurements, both inclusive and differential, can provide stringent tests of perturbative QCD (pQCD). The presented analysis [1] data from proton-proton collisions at s = 8 TeV, corresponding to an integrated luminosity of 10.71 fb−1 are analyzed, and the cross section measurement is performed double-differentially as a function of the jet transverse momentum pT and the absolute jet rapidity |y| .
