The nature of dark matter and properties of neutrinos are among the most pressing issues in
contemporary particle physics. The dual-phase xenon time-projection chamber is the …

Most embeddings of the Standard Model into a more unified theory, in particular those
based on supergravity or superstrings, predict the existence of a hidden sector of particles …

Fixed-target experiments are ideally suited for discovering new MeV–GeV mass U (1) gauge
bosons through their kinetic mixing with the photon. In this paper, we identify the production …

Abstract Extra``hidden''U (1) gauge factors are a generic feature of string theory that is of
particular phenomenological interest. They can kinetically mix with the Standard Model …

In recent years, direct detection, indirect detection, and collider experiments have placed
increasingly stringent constraints on particle dark matter, exploring much of the parameter …

The dense environment of neutron stars makes them an excellent target for probing dark
matter interactions with the Standard Model. We study neutron star heating from capture of …

Experiments designed to measure neutrino oscillations also provide major opportunities for
discovering very weakly-coupled states. In order to produce neutrinos, experiments such as …

We perform a systematic study of the phenomenology associated to models where the dark
matter consists in the neutral component of a scalar SU (2) L n-uplet, up to n= 7. If one …

Light nonrelativistic components of the galactic dark matter halo elude direct detection
constraints because they lack the kinetic energy to create an observable recoil. However …

We initiate the study of novel thermal dark matter (DM) scenarios where present-day
annihilation of DM in the galactic center produces boosted stable particles in the dark sector …
