DOI: 10.1007/jhep07(2018)118
Abstract: A bstractExtra dimensions (ED) can provide a useful tool for model-building. In this paper we introduce a single, flat ED extension of the kinetic-mixing/dark photon (DP) portal for dark matter (DM) interactions with the Standard… read more here.

DOI: 10.1103/physrevd.101.035044
Abstract: That massless dark photons could exist and have flavor-changing magnetic-dipole couplings to down-type light quarks is an attractive possibility which may be realized in various new-physics scenarios. It is potentially testable not only in kaon… read more here.

DOI: 10.1103/physrevd.102.115029
Abstract: We entertain the possibility that massless dark photons exist and have nonnegligible flavor-changing dipole-type couplings to the $u$ and $c$ quarks. Such interactions give rise to the flavor-changing neutral current decays of charmed hadrons into… read more here.

DOI: 10.1103/physrevd.98.023540
Abstract: It is well known that gravitons can convert into photons, and vice versa, in the presence of cosmological magnetic fields. We study this conversion process in the context of the atomic dark matter scenario. In… read more here.

DOI: 10.3390/sym15061167
Abstract: We investigate the prospects for the direct detection of dark matter (DM) particles, incident on the upper atmosphere. A recent work relating the burst-like temperature excursions in the stratosphere at heights of ≈38–47 km with… read more here.
