Links between astroparticle physics and the LHC

Abstract

Research into the fundamental nature of matter at the high energy frontier takes place in three main areas: accelerator-based particle physics, high energy astrophysics, and the cosmology of the early universe. As a consequence the study of astroparticle physics can have significant implications for collider physics at the LHC. Likewise, the LHC project provides the laboratory to perform measurements of great importance for cosmic ray astrophysics and cosmology. This paper reviews some of the important synergistic links between astroparticle and LHC physics.

Data analysis

“…For the soft interactions semi-empirical phenomenological models must be used. The implementation of such approaches based on extrapolations from accelerator data has been used for simulations of extensive air showers (QGSJET, SIBYLL, DPMJET, VENUS, NEXUS, FLUKA [24][25][26], see also Appendix 4). Commonly, such models have been integrated into simulation packages such as CORSIKA [27].…”

O bóson de Higgs

“…No modelo supersimétrico mínimo (MSSM), designa-se a partícula elementar supersimétrica mais leve (estável) como sendo a LSP (Lighest Supersimmetric Particle). Uma das possíveis candidatasà LSPé o neutralino [59]. Acredita-se que o neutralino tenha sido produzido nos primórdios do Universo e que ainda exista atualmente devidoà sua estabilidade, correspondendoà matéria escura observada.…”
