Multiple Axions in Laboratory Experiments

Arturo de Giorgi, Joerg Jaeckel, Sebastian Monath +1

Axions and axion-like particles generically appear in extensions of the Standard Model. While many searches assume only a single axion species, there may exist a whole spectrum of…

GeV ALP from TeV Vector-like leptons

Arturo de Giorgi, Marta Fuentes Zamoro, Luca Merlo

We present a model where a GeV axion-like-particle (ALP) is predicted in a large portion of the parameter space due to the presence of explicit Peccei-Quinn symmetry-breaking terms…

A lesson from $R_{τ τ}^{K^{()}}$ and $R_{ν ν}^{K^{()}}$ at Belle II

Arturo de Giorgi, Gioacchino Piazza

Within the assumption of Left-Handed (LH) New Physics (NP), we review the relations between $B (B \to K^{(*)} τ^{+} τ^{-})$ and $B (B \to K^{(*)} ν ν ˉ)$ for sev…
