# CSM analyses of $t\bar t H, t\bar t Z, t\bar b W^-$ production in gluon-gluon and photon-photon collisions

## TL;DR

This paper investigates how the Composite Standard Model (CSM) affects top quark and Higgs boson production in gluon-gluon and photon-photon collisions, highlighting potential observable differences based on CSM conservation or violation.

## Contribution

It extends previous analyses of $e^+e^-$ collisions to gluon-gluon and photon-photon collisions, exploring the impact of CSM on these processes.

## Key findings

- CSM conserving and violating form factors produce distinguishable effects.
- Differences between CSM effects are significant in gluon-gluon and photon-photon collisions.
- Potential for experimental tests of Higgs and top quark compositeness.

## Abstract

We extend our previous analysis of $t\bar t H, t\bar t Z, t\bar b W$ production in $e^+e^-$ collisions within the CSM (Composite Standard Model) concept of Higgs boson and top quark compositeness to the case of gluon-gluon and photon-photon collisions. We show that remarkable differences may indeed appear between the effects generated by CSM conserving and by CSM violating sets of form factors.
