# High-pT Signatures in Vector-Leptoquark Models

## TL;DR

This paper analyzes collider signatures of TeV-scale vector bosons, including $Z'$, $U_1$ leptoquark, and $G'$, motivated by B-meson decay anomalies, deriving bounds on their masses and couplings.

## Contribution

It provides a comprehensive analysis of collider signatures for three vector boson representations in models addressing B-meson decay anomalies, including interaction assumptions and bounds.

## Key findings

- Derived bounds on masses and couplings of $Z'$, $U_1$, and $G'$
- Constrained a wide range of new physics models
- Analyzed interactions including right-handed and off-diagonal couplings

## Abstract

We present a detailed analysis of the collider signatures of TeV-scale massive vector bosons motivated by the hints of lepton flavour non-universality observed in $B$-meson decays. We analyse three representations that necessarily appear together in a large class of ultraviolet-complete models: a colour-singlet ($Z'$), a colour-triplet (the $U_1$ leptoquark), and a colour octet ($G'$). Under general assumptions for the interactions of these exotic states with Standard Model fields, including in particular possible right-handed and flavour off-diagonal couplings for the $U_1$, we derive a series of stringent bounds on masses and couplings that constrain a wide range of explicit new-physics models.
