We present a new mechanism for thermally produced dark matter, based on a semi-annihilationlike process, χ+χ+ SM→ χ+ SM, with intriguing consequences for the properties of dark matter. First, its mass is low, . 1 GeV (but & 5 keV to avoid structure-formation constraints). Second, it is strongly interacting, leading to kinetic equilibrium between the dark and visible sectors, avoiding the structure-formation problems of χ + χ + χ → χ + χ models. Third, in the 3 → 2 process, one dark matter…

Exploring new physics with O(keV) electron recoils in direct detection experiments

Motivated by the recent XENON1T results, we explore various new physics models that can be discovered through searches for electron recoils in O $$ \mathcal{O} $$ (keV)-threshold direct-detection

Exoplanets as New Sub-GeV Dark Matter Detectors

We present exoplanets as new targets to discover Dark Matter (DM), with advantages due to their large expected abundance, low temperatures, and large sizes. Throughout the Milky Way, DM can scatter,

Exothermic dark matter for XENON1T excess

Motivated by the recent excess in the electron recoil from XENON1T experiment, we consider the possibility of exothermic dark matter, which is composed of two states with mass splitting. The heavier

Electric But Not Eclectic: Thermal Relic Dark Matter for the XENON1T Excess.

TLDR
It is shown that a straightforward model of inelastic dark matter produced via early Universe thermal freeze-out annihilation can account for the XENON1T excess.

U(1) mixing and the weak gravity conjecture

Tiny values for gauge couplings of dark photons allow to suppress their kinetic mixing with ordinary photons. We point out that the Weak Gravity Conjecture predicts consequently low ultraviolet

Neutrino Self-Interactions and XENON1T Electron Recoil Excess.

TLDR
It is shown that such coupling values can naturally arise in a renormalizable model of long-range vector-mediated neutrino self-interactions, and could be distinguished from other explanations of the XENON1T excess by the characteristic 1/T^{2} energy dependence of the neutrinos-electron scattering cross section.

Enabling forbidden dark matter

The thermal relic density of dark matter is conventionally set by two-body annihilations. We point out that in many simple models, $3 \to 2$ annihilations can play an important role in determining

GeV-scale thermal WIMPs: Not even slightly ruled out

Weakly Interacting Massive Particles (WIMPs) have long reigned as one of the leading classes of dark matter candidates. The observed dark matter abundance can be naturally obtained by freezeout of

Mechanism for thermal relic dark matter of strongly interacting massive particles.

TLDR
A new paradigm for achieving thermal relic dark matter is presented and 3→2 annihilations typically predict sizable 2→2 self-interactions which naturally address the "core versus cusp" and "too-big-to-fail" small-scale structure formation problems.

Discovering true muonium at LHCb

We study the potential of the LHCb experiment to discover, for the first time, the $\mu^+\mu^-$ true muonium bound state. We propose a search for the vector $1^3S_1$ state, $\mathcal{T\!M}$, which

Results on MeV-scale dark matter from a gram-scale cryogenic calorimeter operated above ground

Models for light dark matter particles with masses below 1 GeV/c$$^2$$2 are a natural and well-motivated alternative to so-far unobserved weakly interacting massive particles. Gram-scale cryogenic

Tev-scale thermal WIMPs: Unitarity and its consequences

We re-examine unitarity bounds on the annihilation cross section of thermal-WIMP dark matter. For high-mass pointlike dark matter, it is generic to form WIMP bound states, which, together with

Light Dark Matter Search with Ionization Signals in XENON1T.

TLDR
Constraints on light dark matter (DM) models using ionization signals in the XENON1T experiment are reported, and no DM or CEvNS detection may be claimed because the authors cannot model all of their backgrounds.
