The measured branching fractions of -mesons into leptonic final states derived by the LHCb collaboration hint towards the breakdown of lepton flavour universality. In this work…
Searching for pseudo Nambu-Goldstone boson dark matter production in association with top quarks
Ulrich Haisch, Giacomo Polesello, Stefan Schulte
Pseudo Nambu-Goldstone bosons (pNGBs) are attractive dark matter (DM) candidates, since they couple to the Standard Model (SM) predominantly through derivative interactions. Thereb…
