Importance of Loop Effects in Explaining the Accumulated Evidence for New Physics in $B$ Decays with a Vector Leptoquark
/ Crivellin, Andreas ; Greub, Christoph ; Saturnino, Francesco ; Müller, Dario
In recent years experiments revealed intriguing hints for new physics (NP) in $B$ decays involving $b\to c\tau \nu $ and $b\to s{\ell}^{+}{\ell}^{}$ transitions at the $4\sigma $ and $5\sigma $ level, respectively. [...]

Correlating lepton flavor universality violation in $B$ decays with $\mu \to e\gamma $ using leptoquarks
/ Crivellin, Andreas ; Müller, Dario ; Signer, Adrian ; Ulrich, Yannick
Motivated by the measurements of $b\to s{\ell}^{+}{\ell}^{}$ transitions, including $R\left(K\right)$ and $R\left({K}^{*}\right)$, we examine lepton flavor (universality) violation in $B$ decays and its connections to $\mu \to e\gamma $ in generic leptoquark models. [...]

Simultaneous explanation of R ( D (∗) ) and b → sμ + μ − : the last scalar leptoquarks standing
/ Crivellin, Andreas ; Müller, Dario ; Ota, Toshihiko
Over the past years, experiments accumulated intriguing hints for new physics (NP) in flavor observables, namely in the anomalous magnetic moment of the muon ( a μ ), in R ( D (∗) ) = Br( B → D (∗) τ ν) / Br( B → D (∗) ℓν ) and in b → sμ + μ − transitions, which are all at the 3 − 4 σ level. [...]
