# $t_{L,R}$ inclusive distributions as tests of top compositeness

## TL;DR

This paper investigates how modifications in top quark couplings, such as form factors and effective mass, affect inclusive top distributions in electron-positron collisions, providing potential signals of top compositeness.

## Contribution

It introduces a detailed analysis of how top compositeness could alter inclusive top distributions, highlighting observable differences from the Standard Model predictions.

## Key findings

- Large sensitivity of $t_R$ distributions to compositeness effects
- Distinct shape differences between $t_R$ and $t_L$ distributions
- Potential observability of effects even in unpolarized top samples

## Abstract

We consider the inclusive top quark distributions in $e^+e^-\to t_{L,R}+\rm{anything}$. We analyze the modifications of the basic SM contributions which would result from $t_{R}$ compositeness for example from the presence of form factors in the $t_{R}$ couplings and of an effective top mass $m_t(s)$. We also look at parton like contributions representing additional new particle production related to $t_{R}$ constituents. One observes a large sensitivity of the $t_{R}$ inclusive distribution to these various effects with specific shapes differing from those of the $t_{L}$ distribution and we show that these effects may even be also observable in the unpolarized top case.
