New Directions in Kaon Physics: Interference in $K^{0} \to I^¼^{+} I^¼^{-}$ as a New Golden Mode

Teppei Kitahara

The rare decays $K_{L}^{0} \to I^¼^{+} I^¼^{-}$ and $K_{S}^{0} \to I^¼^{+} I^¼^{-}$ have long been regarded as difficult channels to extract short-distance physics because they are dominated by long-dista…

Baryon-Meson Sum Rule for $b \to s I^½ I^ˉ ½$

Teppei Kitahara, Manas Kumar Mohapatra, Kota Sasaki

We derive a robust sum rule among the branching fractions of $I^_{b} \to I^ I^½ I^ˉ ½$ and $B \to K^{(*)} I^½ I^ˉ ½$ , assuming that right-handed neutrinos are decoupled. Despite the…

CP violation in $K \to I^¼^{+} I^¼^{-}$ with and without time dependence through a tagged analysis

Giancarlo D'Ambrosio, Avital Dery, Yuval Grossman +4

We point out that using current knowledge of $B (K_{L}^{0} \to I^¼^{+} I^¼^{-})$ and $B (K_{L}^{0} \to I^^{3} I^^{3})$ , one can extract short-distance information from the combined measurement o…

Kaon Physics: A Cornerstone for Future Discoveries

Jason Aebischer, Atakan Tugberk Akmete, Riccardo Aliberti +153

The kaon physics programme, long heralded as a cutting-edge frontier by the European Strategy for Particle Physics, continues to stand at the intersection of discovery and innovati…
