Tests of the Higgs and top quark properties through inclusive $t\bar t$ production

TL;DR

This paper explores how inclusive top-antitop production in various collision types can detect new particles related to the Higgs sector or top quark, providing a potential method for new physics discovery.

Contribution

It proposes a novel approach to identify new particles through inclusive $t\bar t$ production in different collision environments.

Findings

Inclusive $t\bar t$ production can reveal new particles.

Method applicable to $e^+e^-$, gluon-gluon, and photon-photon collisions.

Potential to detect both visible and invisible particles.

Abstract

We show how the inclusive $t\bar t$ production in $e^+e^-$, gluon~gluon and photon~photon collisions could reveal the presence of new (visible or invisible) particles connected to the Higgs sector and/or to the top quark.
