I discuss a novel method to search for axion-like particles (ALPs) at particle accelerator experiments. ALPs produced at the target subsequently enter a region with a magnetic ?field, where they are converted to photons that are then detected. Dubbed Particle Accelerator helioScopes for Slim Axion-like-particle deTection (PASSAT), this proposal uses the principle of the axion helioscope but...

Exotic compact objects such as primordial black holes, boson star, etc., are theoretically predicted to exist and can make interesting dark matter candidates,

discuss a new method of using gravitational waves from the extreme mass ratio inspiral, formed by an ECO and a supermassive black hole in the center of... -

Motivated by the absence of dark matter signals in dark matter direct search and new physics at LHC, we study new approaches to explore dark matter and baryogenesis

In order to explain the baryon asymmetry of the Universe, we extend the

Standard Model with two additional Higgs doublets with small vacuum expectation values and masses around the TeV scale. These additional Higgs fields introduce new sources of CP violation through complex Yukawa couplings with Standard Model fermions. We propose a flavor model where Yukawa couplings are $\mathcal{O}(1)$... -

We construct a theory in which the solution to the strong CP problem is an emergent property of the background of the dark matter in the Universe. The role of the axion degree of freedom is played by multi-body collective excitations similar to spin-waves in the medium of the dark matter of the Galactic halo. The dark matter is a vector particle whose low energy interactions with the Standard...
