One-loop Dirac neutrino mass and mixed axion/WIMP dark matter
Cristian D. R. Carvajal, Óscar Zapata
We consider the Peccei-Quinn (PQ) mechanism as the one behind the Dirac neutrino masses when these are generated through the effective operator at one…
A novel way to search for light dark matter in lepton beam-dump experiments
L. Marsicano, M. Battaglieri, M. Bondì +7
A novel mechanism to produce and detect Light Dark Matter in experiments making use of GeV electrons (and positrons) impinging on a thick target (beam-dump) is proposed. The positr…
Resonant production of dark photons in positron beam dump experiments
Enrico Nardi, Cristian D. R. Carvajal, Anish Ghoshal +2
Positrons beam dump experiments have unique features to search for very narrow resonances coupled superweakly to pairs. Due to the continue loss of energy from soft photo…
Dark photon production through positron annihilation in beam-dump experiments
L. Marsicano, M. Battaglieri, M. Bondi' +7
High energy positron annihilation is a viable mechanism to produce dark photons (). This reaction plays a significant role in beam-dump experiments using experiments usin…
