                                    A measurement of the top quark pair production (toverline{t} ) cross
section in proton-proton collisions at the centre-of-mass energy of 8
{TeV} is presented using data collected with the CMS detector at the
LHC, corresponding to an integrated luminosity of 19.6 {fb}^{- {1}}.
This analysis is performed in the toverline{t} decay channels with one
isolated, high transverse momentum electron or muon and at least four
jets, at least one of which is required to be identified as originating
from hadronization of a b quark. The calibration of the jet energy scale
and the efficiency of b jet identification are determined from data. The
measured toverline{t} cross section is 228.5 ± 3.8 {(stat)}
± 13.7 {(syst)} ± 6.0 {(lumi)} { pb} . This measurement is
compared with an analysis of 7 {TeV} data, corresponding to an
integrated luminosity of 5.0 {fb}^{- {1}}, to determine the ratio of 8
{TeV} to 7 {TeV} cross sections, which is found to be 1.43 ± 0.04
{(stat)} ± 0.07 {(syst)} ± 0.05 {(lumi)} . The
measurements are in agreement with QCD predictions up to
next-to-next-to-leading order.
