Flavour anomalies from a split dark sector
Luc Darmé, Marco Fedele, Kamila Kowalska +1
We investigate solutions to the flavour anomalies in decays based on loop diagrams of a "split" dark sector characterised by the simultaneous presence of heavy particles at the…

Light Dark Sectors through the Fermion Portal
Luc Darmé, Sebastian A. R. Ellis, Tevong You
Pairs of Standard Model fermions form dimension-3 singlet operators that can couple to new dark sector states. This "fermion portal" is to be contrasted with the lower-dimensional…

Flavor anomalies and dark matter in SUSY with an extra U(1)
Luc Darmé, Kamila Kowalska, Leszek Roszkowski +1
Motivated by the recent anomalies in transitions that emerged at LHCb, we consider a model with an gauge symmetry and additional vector-like fermions. W…
