$t_{L,R}$ inclusive distributions as tests of top compositeness

Abstract

We consider the inclusive top quark distributions in $e^{+}{e}^{-}\to t_{L,R}+\mathrm{anything}$. We analyze the modifications of the basic SM contributions which would result from $t_R$ compositeness for example from the presence of form factors in the $t_R$ couplings and of an effective top mass $m_t(s)$. We also look at parton like contributions representing additional new particle production related to $t_R$ constituents. One observes a large sensitivity of the $t_R$ inclusive distribution to these various effects with specific shapes differing from those of the $t_L$ distribution and we show that these effects may even be also observable in the unpolarized top case.
