CSM tests in $gb\to \gamma b, Hb, Zb, W^-t$ processes

TL;DR

This paper investigates how certain particle production processes in gluon-bottom collisions can reveal potential compositeness of the Higgs, top, and bottom quarks, highlighting energy-dependent signatures.

Contribution

It introduces a method to analyze cross section ratios in specific processes to probe quark and Higgs compositeness at high energies.

Findings

Distinct energy dependence patterns for different quark compositeness assumptions.

Ratios of new to standard cross sections can indicate compositeness signals.

Specific CSM constraints influence Higgs sector predictions.

Abstract

We show that the processes of $\gamma b, Hb, Zb, W^-t$ production in gluon+bottom collision can give interesting informations about possible Higgs boson, top and bottom quark compositeness. We make illustrations of the ratios of new cross sections over standard ones. Specific energy dependences appear for each assumption about $b_L$, $b_R$, $t_L$, $t_R$ compositeness and CSM constraints concerning the Higgs sector.
