Determination of the top-quark pole mass and strong coupling constant from the ttbar production cross section in pp collisions at sqrt(s) = 7 TeV

The inclusive cross section for top-quark pair production measured by the CMS experiment in proton-proton collisions at a center-of-mass energy of 7 TeV is compared to the QCD prediction at next-to-next-to-leading order with various parton distribution functions to determine the top-quark pole mass, m t , or the strong coupling constant, αS. With the parton distribution function set NNPDF2.3, a...

Top Quark Production Dynamics in Qcd *

A calculation of the total cross section for top quark production in hadronhadron collisions is presented based on an all-orders perturbative resummation of initial-state gluon radiative contributions to the basic quantum chromodynamics subprocesses. Principal-value resummation is used to evaluate all relevant large threshold contributions. In this method there are no arbitrary infrared cutoffs...

Measurement of the Top Quark Mass and Properties at the Lhc

Recent measurements of top quark properties using tt̄ events produced in proton-proton collisions at the Large Hadron Collider with centre of mass energies of 7 and 8 TeV and detected by the ATLAS and CMS experiments are presented. These results include top quark mass, the top and anti-top mass difference, top pole mass from the cross section measurement, the charge asymmetry, spin correlation, ...
