LHC Physics and Cosmology

TL;DR

This paper reviews how collider data, especially from the LHC, combined with astrophysical observations, can constrain particle physics models and dark matter theories, emphasizing model dependence and future prospects.

Contribution

It provides a comprehensive analysis of supersymmetric dark matter constraints from collider and astrophysical data across various theoretical frameworks.

Findings

LHC data can impose significant constraints on supersymmetric dark matter models.

Theoretical model dependence affects the interpretation of collider and astrophysical constraints.

Future precision measurements could improve the ability to identify dark matter candidates.

Abstract

In these Lectures I review possible constraints on particle physics models, obtained by means of combining the results of collider measurements with astrophysical data. I emphasize the theoretical-model dependence of these results. I discuss supersymmetric dark matter constraints at colliders (mainly LHC) in various theoretical contexts: the standard Cosmological-Constant-Cold-Dark-Matter (Lambda-CDM) model, (super)string-inspired ones and non-equilibrium relaxation dark energy models. I then investigate the capability of LHC measurements in asserting whether supersymmetric matter (if discovered) constitutes part, or all, of the astrophysical dark matter. I also discuss prospects for improving the constraints in future precision facilities, such as the International Linear Collider.
