### Top quark properties at ATLAS.

Minoru Hirose
Discovered in 1995 by the CDF and D$\O$ experiments at Tevatron, the top quark is the heaviest known elementary particle. Its properties might offer a hint of physics beyond the Standard Model. It is thus of interest to measure them as precisely as possible. We present a summary of property measurements of the top quarks which are produced in pp collisions with $\sqrt{s} = 7~ \mathrm{TeV}$ at the LHC. Measurements of the top quark charge,...
