Context. PKS 1510-089 is one of only a few flat spectrum radio quasars detected in the very-high-energy (VHE, > 100 GeV) gamma-ray band. Aims: We study the broadband spectral and temporal properties of the PKS 1510-089 emission during a high gamma-ray state. Methods: We performed VHE gamma-ray observations of PKS 1510-089 with the Major Atmospheric

The invariance of the standard model (SM) under the CPT transformation predicts equality of particle and antiparticle masses. This prediction is tested by measuring the mass difference between the top quark and antiquark (Δmt =mt -mt‾) that are produced in pp collisions at a center-of-mass energy of 8 TeV, using events with a muon or an electron

The first measurement of the jet mass m_{ {jet}} of top quark jets produced in {t}\overline{t} events from pp collisions at √{s}=8 {TeV} is reported for the jet with the largest transverse momentum pT in highly boosted hadronic top quark decays. The data sample, collected with the CMS detector, corresponds to an integrated luminosity of 19.7 {fb}^{

A measurement is presented of the cross section for the electroweak production of a Z boson and a photon in association with two jets in proton-proton collisions at √{ s} = 8 TeV. The Z bosons are identified through their decays to electron or muon pairs. The measurement is based on data collected with the CMS detector corresponding to an

Inclusive jet spectra from p p and PbPb collisions at a nucleon-nucleon center-of-mass energy of 2.76 TeV , collected with the CMS detector at the CERN Large Hadron Collider, are presented. Jets are reconstructed with three different distance parameters (R =0.2 , 0.3, and 0.4) for transverse momentum (pT) greater than 70 GeV / c and pseudorapidity

Normalized double-differential cross sections for top quark pair (t\overline{t}) production are measured in pp collisions at a centre-of-mass energy of 8 {TeV} with the CMS experiment at the LHC. The analyzed data correspond to an integrated luminosity of 19.7 {fb}^{-1}. The measurement is performed in the dilepton e^{± }μ ^{∓ } final state. The t
