Hiding a Light Vector Boson from Terrestrial Experiments: A Chargephobic Dark Photon

Haidar Esseili, Graham D. Kribs

We calculate the terrestrial, astrophysical and cosmological constraints on a light vector boson that couples to an arbitrary combination of the electromagnetic and $B - L$ currents…

Cosmological Implications of Gauged $U (1)_{B - L}$ on $Δ N_{eff}$ in the CMB and BBN

Haidar Esseili, Graham D. Kribs

We calculate the effects of a light, very weakly-coupled boson $X$ arising from a spontaneously broken $U (1)_{B - L}$ symmetry on $Δ N_{eff}$ as measured by the CMB and $Y_{p}$ from…
