Light stop squarks and b-tagging

TL;DR

This paper reviews the challenges in detecting light stop squarks at colliders, especially around the top quark mass, and proposes b-tagging strategies to improve search coverage in these difficult regions.

Contribution

It introduces new strategies based on b-tagging to better constrain light stop squarks in collider experiments, addressing gaps in current search methods.

Findings

Identification of unconstrained stop mass regions near the top quark mass.

Proposed b-tagging based strategies to improve detection sensitivity.

Enhanced coverage of light stop parameter space in collider searches.

Abstract

A significant part of the parameter space for light stop squarks still remains unconstrained by collider searches. For both R-Parity Conserving (RPC) and R-Parity Violating (RPV) scenarios there are regions in which the stop mass is around or below the top quark mass that are particularly challenging experimentally. Here we review the status of light stop searches, both in RPC and RPV scenarios. We also propose strategies, generally based on exploiting b-tagging, to cover the unconstrained regions.
