Unbinned extraction of $I^^{3}$ from $B \to D K$ with normalizing flows

Yuval Grossman, Tony Menzo, Stefan Schacht +2

We introduce an unbinned method for extracting the CKM angle $I^^{3}$ from the decay chain $B^{\pm} \to (D \to K_{S} I ¨ ^{+} I ¨ ^{-}) K^{\pm}$ using normalizing flows (NFs). The NFs, trained on $D…

$C P$ violation in neutral kaon mixing in $D^{0} \to K_{S} K_{S}$

Yuval Grossman, Guglielmo Papiri, Stefan Schacht

We study CP violation induced by neutral kaon mixing in $a_{C P} (D^{0} \to K_{S} K_{S})$ . We show that the contribution from neutral kaon mixing arises only in connection with sec…

One Sum To Rule Them All: A Second Order Master Rate Sum Rule for Charm Decays

Margarita Gavrilova, Yuval Grossman, Guglielmo Papiri +1

We show that within the Standard Model any system of hadronic weak charm decays related by $U$ -spin satisfies the following rate sum rule: (sum of CF and DCS CKM-free rates) divide…

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…

Systematics of U-Spin Sum Rules for Systems with Direct Sums

Margarita Gavrilova, Stefan Schacht

A rich mathematical structure underlying flavor sum rules has been discovered recently. In this work, we extend these findings to systems with a direct sum of representations. We p…
