We consider direct-detection searches for sub-GeV dark matter via electron scatterings in
the presence of large interactions between dark and ordinary matter. Scatterings both on …

We identify what may be the world's most sensitive location to search for millicharged
particles in the 10 MeV to 100 GeV mass range: the forward region at the LHC. We propose …

We study cosmic-ray-atmosphere collisions as a permanent production source of exotic
millicharged particles (MCPs) for all terrestrial experiments.[MCPs are also known as …

Dark matter (DM) could be a relic of freeze-in through a light mediator, where the DM is
produced by extremely feeble, IR-dominated processes in the thermal standard model …

The scattering of light dark matter off thermal electrons inside the Sun produces a “fast”
subcomponent of the dark matter flux that may be detectable in underground experiments …

We derive constraints on millicharged dark matter and axionlike particles using pulsar timing
and fast radio burst observations. For dark matter particles of charge ε e, the constraint from …

These lectures, presented at the 2021 Les Houches Summer School on Dark Matter, provide
an introduction to key methods and tools of indirect dark matter searches, as well as a status …

A bstract We study the simplest theories with exact spacetime parity that solve the strong CP
problem and successfully generate the cosmological baryon asymmetry via decays of right …

We present a novel unifying interpretation of excess event rates observed in several dark
matter direct-detection experiments that utilize single-electron threshold semiconductor …

Light sub-GeV dark matter (DM) constitutes an underexplored target, beyond the optimized
sensitivity of typical direct DM detection experiments. We comprehensively investigate …
