Recent results from several direct detection experiments have imposed severe constraints on the multi-GeV mass window for various dark mat- ter(DM) models. However, many of these experiments are not sensitive
to MeV scale DM as the corresponding recoil energies are much below the detector thresholds. In this regard, we reexamined the light scalar DM in a model-independent approach in our...
Dark matter-motivated light dark sectors often feature long-lived hidden sector states. Their presence offers bright detection prospects at fixed target experiments and colliders and may lead to strong astrophysical bounds. We will illustrate this point by exploring explicitly a typical simple fermion light dark matter setup, then expanding to limits on an effective theory of light dark...
The status of the research on effective field theories for lepton dipole moments will be reviewed. Standard Model Effective Field Theories (SMEFTs) at high and low energies will be reviewed in light of current and future bounds from experiments on lepton flavour violation. In addition, some modern techniques for multi-loop computations in SMEFTs will be reviewed and applications to...
