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 -spin satisfies the following rate sum rule: (sum of CF and DCS CKM-free rates) divide…

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…
