Theory

I’ll review some recent attempts to model the production of GeV-scale dark sector degrees of freedom, including dark photons, via proton bremsstrahlung at accelerators and fixed target experiments.

19. Axion-sourced Gravitational Waves in B-L Hybrid Inflation

Theory

Minimal supersymmetric $B-L$ hybrid inflation predicts a negligible vacuum tensor-to-scalar ratio $r_{\mathrm{vac}}\sim 10^{-8}$ due to its extremely flat potential. In this letter, we show that adding a spectator axion-like field coupled to the $U(1)_{B-L}$ gauge sector via a Chern-Simons term circumvents this suppression. The rolling axion triggers a tachyonic instability for one gauge-field...
