# CSM analyses of $e^+e^- \to t\bar t H, t\bar t Z, t\bar b W$

## TL;DR

This paper investigates how Higgs boson and top quark compositeness, within the CSM framework, can alter the amplitudes and cross sections of key processes like e+e- to t tbar H, t tbar Z, and t b W, highlighting observable differences.

## Contribution

It introduces a detailed analysis of amplitude and cross section modifications due to Higgs and top compositeness within the CSM model, comparing CSM conserving and violating scenarios.

## Key findings

- Observable differences between CSM conserving and violating compositeness scenarios.
- Potential signatures in cross sections indicating Higgs and top quark compositeness.
- Guidance for experimental searches for compositeness effects.

## Abstract

We study the modifications of the amplitudes and cross sections of several processes, especially $e^+e^- \to t\bar t H, t\bar t Z, t\bar b W$, generated by Higgs boson and top quark compositeness, in particular within the CSM concept. We illustrate the observable differences that may appear between various, CSM conserving or CSM violating, compositeness possibilities.
