TL;DR
This paper explores how LHC physics can shed light on cosmological issues like dark matter and matter-antimatter asymmetry, and discusses the role of cosmological perturbations in understanding early universe epochs.
Contribution
It connects particle physics phenomena observed at the LHC with cosmological problems, highlighting potential insights into dark matter and baryogenesis.
Findings
WIMPs as cold dark matter candidates
Gravitinos as warm dark matter candidates
Electroweak baryogenesis as a matter-antimatter asymmetry mechanism
Abstract
In these lectures we first concentrate on the cosmological problems which, hopefully, have to do with the new physics to be probed at the LHC: the nature and origin of dark matter and generation of matter-antimatter asymmetry. We give several examples showing the LHC cosmological potential. These are WIMPs as cold dark matter, gravitinos as warm dark matter, and electroweak baryogenesis as a mechanism for generating matter-antimatter asymmetry. In the remaining part of the lectures we discuss the cosmological perturbations as a tool for studying the epoch preceeding the conventional hot stage of the cosmological evolution.
