Searches for Scalar and Vector Leptoquarks at Future Hadron Colliders

TL;DR

This paper evaluates the potential for future hadron colliders to discover scalar and vector leptoquarks by analyzing production cross sections and discovery reach up to 200 TeV energies.

Contribution

It provides detailed estimates of production cross sections for scalar and vector leptoquarks at future colliders, highlighting their discovery potential in the TeV mass range.

Findings

Future colliders can discover leptoquarks up to a few TeV in mass.

Production cross sections are significant at TeV33, LHC, and proposed 60 and 200 TeV colliders.

Discovery is feasible through quark-antiquark annihilation and gluon-gluon fusion processes.

Abstract

The search reaches for both scalar($S$) and vector($V$) leptoquarks at future hadron colliders are summarized. In particular we evaluate the production cross sections of both leptoquark types at TeV33 and LHC as well as the proposed 60 and 200 TeV colliders through both quark-antiquark annihilation and gluon-gluon fusion: $q \bar q, gg \to SS,VV$. Experiments at these machines should easily discover such particles if their masses are not in excess of the few TeV range.
