In this report we present the measurement of the ttbar differential cross section for high pT top quarks as a function of their transverse momentum using pp collisions at √s= 8 TeV collected by the ATLAS detector and corresponding to an integrated luminosity of 20.3 fb^(-1) . The techniques used in the analysis are optimized for the identification and reconstruction of hadronically decaying top quarks with high Lorentz boost and allow to extend the measurement to the TeV region. The observed yield is corrected for detector effects and the differential cross section obtained is compared with several NLO theoretical predictions both in a fiducial region and in the full phase.

Abstract
In this report we present the measurement of the ttbar differential cross section for high pT top quarks as a function of their transverse momentum using pp collisions at √s= 8 TeV collected by the ATLAS detector and corresponding to an integrated luminosity of 20.3 fb^(-1) . The techniques used in the analysis are optimized for the identification and reconstruction of hadronically decaying top quarks with high Lorentz boost and allow to extend the measurement to the TeV region. The observed yield is corrected for detector effects and the differential cross section obtained is compared with several NLO theoretical predictions both in a fiducial region and in the full phase.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
