Specific three-loop contributions to $b \to s γ$ associated with the current-current operators

Christoph Greub, Hrachia M. Asatrian, Francesco Saturnino +1

We work out a specific class of three-loop diagrams (of order $α_{s}^{2}$ ) contributing to the decay amplitude for $b \to s γ$ associated with the current-current operators $O_{1}$ and $…

Scalar Leptoquarks in Leptonic Processes

Andreas Crivellin, Christoph Greub, Dario Müller +1

Leptoquarks are hypothetical new particles, which couple quarks directly to leptons. They experienced a renaissance in recent years as they are prime candidates to explain the so-c…

Correlating $h \to μ^{+} μ^{-}$ to the Anomalous Magnetic Moment of the Muon via Leptoquarks

Andreas Crivellin, Dario Mueller, Francesco Saturnino

Recently, both ATLAS and CMS measured the decay $h \to μ^{+} μ^{-}$ , finding a signal strength with respect to the Standard Model expectation of $1.2 \pm 0.6$ and $1.19\substack{+0.41+0.17\…

Leptoquarks in Oblique Corrections and Higgs Signal Strength: Status and Prospects

Andreas Crivellin, Dario Mueller, Francesco Saturnino

Leptoquarks (LQs) are predicted within Grand Unified Theories and are well motivated by the current flavor anomalies. In this article we investigate the impact of scalar LQs on Hig…

Flavor Phenomenology of the Leptoquark Singlet-Triplet Model

Andreas Crivellin, Dario Müller, Francesco Saturnino

In recent years, experiments revealed intriguing hints for new physics (NP) in semi-leptonic $B$ decays. Both in charged current processes, involving $b \to c τ ν$ transitions, and…

Explaining the Flavor Anomalies with a Vector Leptoquark (Moriond 2019 update)

Andreas Crivellin, Francesco Saturnino

Several experiments revealed intriguing hints for lepton flavor universality (LFU) violating new physics (NP) in semi-leptonic $B$ meson decays, mainly in $b \to c τ ν$ and $b \to s…

Correlating Tauonic B Decays to the Neutron EDM via a Scalar Leptoquark

Andreas Crivellin, Francesco Saturnino

In this article we investigate the correlations between tauonic $B$ meson decays (e.g. $B \to τ ν$ , $B \to D^{(*)} τ ν$ , $B \to π τ ν$ ) and electric dipole moments (EDMs), in particular th…
