Measurement of the Inclusive Jet Cross Section in pp Collisions at √s= 7 TeV

The inclusive jet cross section is measured in pp collisions with a center-of-mass energy of 7 TeV at the LHC using the CMS experiment. The data sample corresponds to an integrated luminosity of 34 pb−1. The measurement is made for jet transverse momenta in the range 18–1100 GeV and for absolute values of rapidity less than 3. The measured cross section extends to the highest values of jet pT ever observed and, within the experimental and theoretical uncertainties, is generally in agreement with next-to-leading-order perturbative QCD predictions.

Study of W boson production in pPb collisions at vsNN = 5.02 TeV

Article history: Received 19 March 2015 Received in revised form 6 September 2015 Accepted 23 September 2015 Available online 28 September 2015 Editor: M. DoserThe first study of W boson production in pPb collisions is presented, for bosons decaying to a muon or electron, and a neutrino. The measurements are based on a data sample corresponding to an integrated luminosity of 34.6 nb−1 at a nucleon-nucleon centre-of-mass energy of sNN = 5.02 TeV, collected by the CMS experiment. The W boson differential cross sections, lepton charge asymmetry, and forward-backward asymmetries are measured for leptons of transverse momentum exceeding 25 GeV/c, and as a function of the lepton pseudorapidity in the |ηlab| < 2.4 range. Deviations from the expectations based on currently available parton distribution functions are observed, showing the need for including W boson data in nuclear parton distribution global fits.

Top quark mass measurements with CMS

The top quark mass is a fundamental parameter of the Standard Model (SM). Precise measurements constrains important SM observables like the Higgs boson mass. The CMS experiment has performed several mesurements of the top quark mass with different techniques in order to have a better understanding and precision in that parameter. The results presented in this document, correspond to the latest measurements performing by CMS detector using data taken in 2010, 2011 and 2012 in pp collisions at the LHC.
