Perturbative unitarity constraints on generic Yukawa interactions

Lukas Allwicher, Pere Arnan, Daniele Barducci +1

We study perturbative unitarity constraints on generic Yukawa interactions where the involved fields have arbitrary quantum numbers under an $\prod_{i} S U (N_{i}) \otimes U (1)$ group. W…

Generic Loop Effects of New Scalars and Fermions in $b \to s ℓ^{+} ℓ^{-}$ , $(g - 2)_{μ}$ and a Vector-like $4^{th}$ Generation

Pere Arnan, Andreas Crivellin, Marco Fedele +1

In this article we investigate in detail the possibility of accounting for the $b \to s ℓ^{+} ℓ^{-}$ and $(g - 2)_{μ}$ anomalies via loop contributions involving with new scalars and fe…

Probing low energy scalar leptoquarks by the leptonic $W$ and $Z$ couplings

Pere Arnan, Damir Becirevic, Federico Mescia +1

We compute the generic one-loop contribution involving scalar leptoquarks (LQ) to the $W$ and $Z$ leptonic decay widths. In our computation we include for the first time the finite…

Two Higgs Doublet Models and $b \to s$ exclusive decays

Pere Arnan, Damir Bečirević, Federico Mescia +1

We computed the leading order Wilson coefficients relevant to all the exclusive $b \to s ℓ^{+} ℓ^{-}$ decays in the framework of Two Higgs Doublet Model (2HDM) with a softly broken…

Loop effects of heavy new scalars and fermions in $b \to s μ^{+} μ^{-}$

Pere Arnan, Andreas Crivellin, Lars Hofer +1

Recent measurements of $b \to s μ^{+} μ^{-}$ processes at LHCb and BELLE have revealed tensions at the $2 - 3 σ$ level between the Standard Model (SM) prediction and the experimental resul…

Interpreting a 2 TeV resonance in WW scattering

Pere Arnan, Domenec Espriu, Federico Mescia

A diboson excess has been observed ---albeit with very limited statistical significance--- in $W W$ , $W Z$ and $Z Z$ final states at the LHC experiments using the accumulated 8 TeV da…
