Tests of the charged Goldstone sector through inclusive $t\bar{b}$ production

Similarly to the previously studied case of inclusive $t\bar{t}$ production we consider the inclusive $t\bar{b}$ production in $e^{+}{e}^{-}$, gluon~gluon and photon~photon collisions. We show how it is sensitive to new physics, connected to the charged Goldstone sector and possibly generated by Higgs and/or top quark compositeness.
