Dark photon distortions of NO $I^½$ A and T2K neutrino oscillations

Gonzalo Alonso-Ãlvarez, James M. Cline, Benoit Laurent +1

Dark photons coupling to $L_{I^} ¼ - L_{I ¨} $ lepton number difference are a highly studied light dark matter candidate, with potential to be discovered through their impact on terrestrial…

The first limit on invisible decays of $B_{s}$ mesons comes from LEP

Gonzalo Alonso-Ãlvarez, Miguel Escudero

Motivated by the recent evidence for $B^{+} \to K^{+} I^ˉ ½ I^½$ decays at Belle II, we point out that fully invisible $B_{d}$ and $B_{s}$ meson decays are strongly constrained by LEP. A rei…

Self-interacting dark matter solves the final parsec problem of supermassive black hole mergers

Gonzalo Alonso-Ãlvarez, James M. Cline, Caitlyn Dewar

Evidence for a stochastic gravitational wave (GW) background, plausibly originating from the merger of supermassive black holes (SMBHs), is accumulating with observations from puls…
