Precision measurement of the top quark mass from M_{b l} distribution in t -> b l νdecays

Abstract

The method of the top quark mass measurement from $M_{b l}$ distribution in $t \to b l ν$ decays can be considerably improved if applying the technique of moments and proceeding to moments of high degree. At the LHC this allows one to reduce the systematic and statistical errors of the top mass by more than a factor of two.
