# Measurements of the top-quark mass and production cross section at CMS

## by Pedro Silva (CERN)

Tuesday, 16 October 2012 from to (Europe/Zurich)
at CERN ( 500-1-001 - Main Auditorium )
 Description Recent measurements of the top mass at CMS are presented, based on several channels and different techniques. The results are combined giving a precise determination of the top mass. The measurements of the ttbar and single top production cross sections at 7 TeV and 8 TeV centre-of-mass energy are reviewed. The ttbar production cross section is utilized to derive a precise determination of the strong coupling constant, the single top cross section is interpreted in terms of the CKM element V_tb Material: Organised by M.
