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

TL;DR

This paper investigates how inclusive t-bbar production in various collision types can reveal new physics related to the charged Goldstone sector, potentially indicating Higgs or top quark compositeness.

Contribution

It extends previous studies of top pair production to include t-bbar production, highlighting its sensitivity to new physics in the charged Goldstone sector.

Findings

Inclusive t-bbar production is sensitive to new physics.

Potential signals of Higgs or top quark compositeness.

Analysis across e+e-, gluon-gluon, and photon-photon collisions.

Abstract

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.
