DOI: 10.1088/1475-7516/2020/01/056
Abstract: With several proposed MeV gamma-ray telescopes on the horizon, it is of paramount importance to perform accurate calculations of gamma-ray spectra expected from sub-GeV dark matter annihilation and decay. We present hazma, a python package… read more here.

DOI: 10.1088/1475-7516/2023/04/020
Abstract: The ionization signal provide an important avenue of detecting light dark matter. In this work, we consider the sub-GeV inelastic dark matter and use the non-relativistic effective field theory (NR-EFT) to derive the constraints on… read more here.

DOI: 10.1103/physrevd.104.115019
Abstract: We propose a Standard Model extension by a U(1)R gauge symmetry where only right-handed chiral fermions can carry a non-trivial charge. Here we show that the simplest anomaly-free solution to accommodate the proton charge radius… read more here.

DOI: 10.1103/physrevd.98.116009
Abstract: We consider photon signals arising from the annihilation or decay of low-mass (sub-GeV) dark matter which couples dominantly to quarks. In this scenario, the branching fractions to the various kinematically accessible hadronic final states can… read more here.

DOI: 10.1103/physrevlett.126.091804
Abstract: We point out a new type of diurnal effect for the cosmic ray boosted dark matter (DM). The DM-nucleon interactions not only allow the direct detection of DM with nuclear recoils but also allow cosmic… read more here.

DOI: 10.1142/s0217751x19500295
Abstract: Many-brane Universes are at the heart of several cosmological scenarios related to physics beyond the Standard Model. It is then a major concern to constrain these approaches. Two-brane Universes involving [Formula: see text]-broken 5D bulks… read more here.
