Phenomenological aspects of flavoured dark matter

TL;DR

This paper reviews a simplified flavoured dark matter model where dark matter interacts with quarks, leading to new flavour-violating signals detectable in meson decays, collider, and direct detection experiments.

Contribution

It introduces a flavoured dark matter model with quark couplings that extend beyond Minimal Flavour Violation, exploring its phenomenological implications.

Findings

Dark matter coupling to quarks induces new flavour violation signals.

Model predicts observable signatures in rare meson decays.

Implications for collider and direct detection experiments are discussed.

Abstract

Flavour symmetries in the dark sector are a theoretically motivated and phenomenologically appealing concept. The dark matter particle can be stabilised with the help of flavour symmetries, without the need to introduce an additional discrete symmetry by hand. Apart from the usual searches in direct and indirect detection experiments and high energy colliders, flavoured dark matter generally also gives rise to new flavour violating interactions leading to interesting signatures in rare meson decays. This proceedings article reviews a simplified model of flavoured dark matter in which the dark matter coupling to quarks constitutes a new source of flavour violation, so that the model goes beyond Minimal Flavour Violation. Particular emphasis is put on the discussion of its phenomenological implications in flavour, collider and direct detection experiments.
