Abstrakt

Within the Λ-CDM framework, Planckian Interacting Dark Matter (PIDM) is a minimal paradigm for dark matter with only one free parameter (the dark matter mass), and the interactions with the standard model of particles fixed by the equivalence principle. The correct PIDM abundance can be successfully obtained by gravitational scattering in the initial thermal plasma of the Standard Model sector if the reheating temperature is sufficiently high, for PIDM masses ranging between 100GeV and the GUT scale. The important case of a GUT scale PIDM mass interestingly predicts an observational amount of primordial gravitational wave from inflation. I will discuss the PIDM paradigm, focussing on the production mechanism, but also mention specific realisations of the PIDM in quantum gravity and known models of inflation. Finally I will discuss the possibility of indirect detection of PIDM through non-perturbative decay, and the possible of a darkly charged PIDM, which could be related to the small scale problems of Large Scale Structure (LSS) formation.
