Magnetic-dipole corrections to $R_{K}$ and $R_{K^{*}}$ in the Standard Model and Dark Photon scenarios

Emidio Gabrielli, Marco Palmiotto

In this work we evaluate the long-distance QED contributions, induced by the magnetic-dipole corrections to the final charged leptons, on the $B$ meson decay widths $B\to (K,K^*) \…

Gravitational traces of broken gauge symmetries

Aleksandr Azatov, Daniele Barducci, Francesco Sgarlata

We investigate first order phase transitions arising from hidden sectors which are in thermal equilibrium with the Standard Model bath in the Early Universe. Focusing on two simpli…

Inflaxion Dark Matter

Takeshi Kobayashi, Lorenzo Ubaldi

A new mechanism for producing axion dark matter is proposed. By invoking low-scale inflation and a kinetic mixing between the axion and the inflaton, it is shown that the axion is…

Probing Dark-ALP Portals at Future $e^{+} e^{-}$ Colliders

Sanjoy Biswas, Anirban Chatterjee, Emidio Gabrielli +1

We study portal interactions connecting visible and dark sectors, and involving local interactions of a photon, a dark photon and a axion-like particle (ALP) at future $e^{+} e^{-}$ col…

Left-Right Supersymmetry as the Origin of Flavor Physics

Sean Fraser, Emidio Gabrielli, Carlo Marzo +2

We propose a new framework for the observed flavor hierarchy and mixing based on left-right supersymmetry. The model contains the most minimal Higgs sector consisting only of gauge…

Charged neutron stars and observational tests of a dark force weaker than gravity

Marco Fabbrichesi, Alfredo Urbano

We discuss the possibility of exploring an unbroken U(1) gauge interaction in the dark sector by means of gravitational waves. Dark sector states charged under the dark force can g…
