Measurement of the $t\bar{t}$ differential cross section at large top quark transverse momentum in $\sqrt{s}$=8 TeV $pp$ collisions using the ATLAS detector at the LHC

The top quark is the heaviest particle in Standard Model. When it is produced with a large Lorentz boost, its decay products tend to overlap, making the standard reconstruction techniques inefficient; large-R jet substructure analysis techniques allow to increase the detection efficiency for these e...

description The top quark is the heaviest particle in Standard Model. When it is produced with a large Lorentz boost, its decay products tend to overlap, making the standard reconstruction techniques inefficient; large-R jet substructure analysis techniques allow to increase the detection efficiency for these events. Differential cross section measurements of boosted $t\bar{t}$ from $pp$ collisions with $\sqrt{s}$ = 8 TeV will be shown, with respect to transverse momentum, mass and rapidity of the $t\bar{t}$ system, using a sample of 20 fb$^{-1}$ recorded by ATLAS during 2012.
