Recent developments on direct $C P$ violation in the kaon system and connection to $K \to π ν ν ˉ$ measurements

Teppei Kitahara

The first lattice result from the RBC and UKQCD Collaborations and improved perturbative calculations of $ε_{K}^{'} / ε_{K}$ have implied that the Standard-Mod…

Impact of polarization observables and $B_{c} \to τ ν$ on new physics explanations of the $b \to c τ ν$ anomaly

Monika Blanke, Andreas Crivellin, Stefan de Boer +4

The combined analysis of the BaBar, Belle, and LHCb data on $B \to D τ ν$ , $B \to D^{*} τ ν$ and $B_{c} \to J /Ψ τ ν$ decay observables shows evidence of physics beyond the Standard Model (SM).…

$D^{}$ polarization vs. $R_{D^{()}}$ anomalies in the leptoquark models

Syuhei Iguro, Teppei Kitahara, Yuji Omura +2

Polarization measurements in $B ˉ \to D^{(*)} τ ν$ are useful to check consistency in new physics explanations for the $R_{D}$ and $R_{D^{*}}$ anomalies. In this…

SMEFT top-quark effects on $Δ F = 2$ observables

Motoi Endo, Teppei Kitahara, Daiki Ueda

We investigate model independent top-quark corrections to $Δ F = 2$ processes for the down-type quarks within the framework of the Standard Model Effective Field Theory. Dimension-s…

Soft-Photon Corrections to $B ˉ \to D τ^{-} ν ˉ_{τ}$ Relative to $B ˉ \to D μ^{-} ν ˉ_{μ}$

Stefan de Boer, Teppei Kitahara, Ivan Nisandzic

We evaluate long-distance electromagnetic (QED) contributions to $B ˉ^{0} \to D^{+} τ^{-} ν ˉ_{τ}$ and $B^{-} \to D^{0} τ^{-} ν ˉ_{τ}$ relative to $B ˉ^{0} \to D^{+} μ^{-} ν ˉ_{μ}$ …
