Cross section measurement of t-channel single top quark production in pp collisions at s=13TeV

open access: yesPhysics Letters B, 2017
The cross section for the production of single top quarks in the t channel is measured in proton–proton collisions at 13TeV with the CMS detector at the LHC. The analyzed data correspond to an integrated luminosity of 2.2fb−1.

Search for standard model production of four top quarks in proton–proton collisions at s=13 TeV

open access: yesPhysics Letters B, 2017
A search for events containing four top quarks (tt¯tt¯) is reported from proton–proton collisions recorded by the CMS experiment at s=13 TeV and corresponding to an integrated luminosity of 2.6 fb−1. The analysis considers the single-lepton (e or μ)+jets

Measurement of the mass difference between top quark and antiquark in pp collisions at s=8 TeV

open access: yesPhysics Letters B, 2017
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
