New physics implications of recent search for $K_{L} \to π^{0} ν ν ˉ$ at KOTO

Teppei Kitahara, Takemichi Okui, Gilad Perez +2

The KOTO experiment recently reported four candidate events in the signal region of $K_{L} \to π^{0} ν ν ˉ$ search, where the standard model only expects $0.10 \pm 0.02$ events. If conf…

The electroweak effective field theory from on-shell amplitudes

Gauthier Durieux, Teppei Kitahara, Yael Shadmi +1

We apply on-shell methods to the bottom-up construction of electroweak amplitudes, allowing for both renormalizable and non-renormalizable interactions. We use the little-group cov…

Addendum to "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, Teppei Kitahara +3

In this addendum to arXiv:1811.09603 we update our results including the recent measurement of $R (D)$ and $R (D^{*})$ by the Belle collaboration: ${\cal R}(D)_{\rm Belle…
