Left-handed physics is not right for leptonic EDMs Open
Heavy New Physics models with lepton flavour-changing interactions are motivated by neutrino masses, and generically induce dipole interactions for charged leptons – which can be flavour-changing ( $$l_j\rightarrow l_i \gamma $$ …

Asymmetric dark matter in SUSY with approximate 𝖱-symmetry Open
We implement the asymmetric dark matter framework, linking the ordinary and dark matter abundances, within a supersymmetric context. We consider a supersymmetric model that respects an approximate U(1) R symmetry, which is broken in such a…

Left-Handed Physics is not right for EDMs Open
Heavy New Physics models with lepton flavour-changing interactions are motivated by neutrino masses, and generically induce dipole interactions for leptons, which can be flavour-changing ($l_j\to l_i γ$) or flavour-diagonal (magnetic and e…

Electric Dipole Moments as indirect probes of dark sectors Open
A bstract Dark sectors provide beyond Standard Model scenarios which can address unresolved puzzles, such as the observed dark matter abundance or the baryon asymmetry of the Universe. A naturally small portal to the dark sector is obtaine…

Completing the one-loop νSMEFT renormalization group evolution Open
A bstract In this work we consider the Standard Model Effective Field Theory extended with right-handed neutrinos, the ν SMEFT, and calculate the full set of one-loop anomalous dimensions that are proportional to Yukawa couplings. These co…

A viable $$L_e-L_\mu $$ model with $$\mu \rightarrow e$$ violation Open
We extend the Standard Model gauge group by $$U(1)_{L_e-L_\mu }$$ and introduce two scalars, a doublet and a singlet, that are charged under this new group and have lepton flavour violating couplings. Since in this model $$…

Semi-inclusive lepton flavor universality ratio in transitions Open
We construct a semi-inclusive lepton flavor universality (LFU) ratio, RΣ, to test μ/e universality in b→sℓ+ℓ− transitions at e+e− B-meson factories. Combining different decay channels, this observable maximizes the sensitivity to possible …
