Description

A preliminary study of the top-quark width ($\Gamma_{top}$) is performed using the ATLAS collaboration official Monte Carlo (MC) samples corresponding to proton-proton collisions with centre of mass energy of $\sqrt{s}$ = 8 TeV and scaled to integrated luminosity $\int Ldt$ = 20.3$fb^{-1}$. Templates with different values of $\Gamma_{top}$ are generated assuming an underlying truth top mass distribution with relativistic Breit-Wigner shape, as modelled in the MC generator. The reconstructed top mass has been obtained by minimising a $\chi^{2}$ function and simulated experiments have been studied.
