A measurement of the underlying event (UE) activity in proton-proton collisions is performed using events with charged-particle jets produced in the central pseudorapidity region (| η jet| < 2) and with transverse momentum 1 ≤ p {T/jet} < 100 GeV. The analysis uses a data sample collected at a centre-of-mass energy of 2.76 TeV with the CMS

A measurement is presented of the Z/γ ^{*} → τ τ cross section in {pp} collisions at √{s} = 13 TeV, using data recorded by the CMS experiment at the LHC, corresponding to an integrated luminosity of 2.3 fb^{-1}. The product of the inclusive cross section and branching fraction is measured to be σ ( {pp} → Z/γ ^{*} {+X}) B(Z/γ ^{*} → τ τ ) = 1848 ±

An inclusive measurement of the Zγ → ν ν ‾ γ production cross section in pp collisions at √{ s} = 8TeV is presented, using data corresponding to an integrated luminosity of 19.6 fb-1 collected with the CMS detector at the LHC. This measurement is based on the observation of events with large missing energy and with a single photon with transverse

We study the extinction properties of dust in the well-defined dust lanes of four highly inclined galaxies using U-, B-, V-, R- and I-band CCD and J- and K'-band Near-Infrared array images. For three of these galaxies, we could use the symmetry of the underlying light profile to obtain absolute extinction values in the dust lanes. Maximum values

The charge asymmetry in t t ‾ events is measured using dilepton final states produced in pp collisions at the LHC at √{ s} = 8TeV. The data sample, collected with the CMS detector, corresponds to an integrated luminosity of 19.5fb-1. The measurements are performed using events with two oppositely charged leptons (electrons or muons) and two or more

The CMS Collaboration presents the first measurement of the differential cross section of jets from charm quarks produced in proton-lead (pPb) collisions at a nucleon-nucleon center-of-mass energy of √{sNN} = 5.02TeV, as well as results from charm quark jets in proton-proton (pp) collisions at √{ s} = 2.76 and 5.02TeV. By comparing the yields of
