Long-living superpartners in the MSSM

TL;DR

This paper explores specific parameter regions in the MSSM where long-lived charged superparticles, such as staus and stops, can exist, highlighting their potential phenomenological implications.

Contribution

It identifies and analyzes particular MSSM parameter regions that allow for long-lived superparticles, expanding understanding of their possible phenomenology.

Findings

Long-lived charged superparticles can exist in certain MSSM parameter regions.

Two key regions are co-annihilation with light staus and large negative A with light stops.

Phenomenology of these long-lived particles is briefly discussed.

Abstract

The parameter space of the Constrained Minimal supersymmetric Standard Model is considered. It is shown that for the particular choice of parameters there are some regions where long-living charged superparticles exist. Two regions of interest are the co-annihilation region with light staus, and the region with large negative trilinear scalar coupling A distinguished by light stops. The phenomenology of long-living superparticles is briefly discussed.
