FlaSR: A Mathematica Package for the Automatic Generation of -spin Sum Rules
Margarita Gavrilova, Livia Kong
We present FlaSR, a Mathematica package for the automatic generation of higher-order amplitude and amplitude-squared flavor sum rules, with a particular emphasis on -spi…
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…
Determination of the ratio of penguin over tree diagrams
Margarita Gavrilova, Yuval Grossman, Stefan Schacht
We study the penguin over tree ratio in decays. This ratio can serve as a probe for rescattering effects. Assuming the Standard Model and in the isospin limit, we…
Fermion pair radiation from accelerating classical systems
Margarita Gavrilova, Mitrajyoti Ghosh, Yuval Grossman +2
Accelerating classical systems that couple to a fermion-antifermion pair at the microscopic level can radiate pairs of fermions and lose energy in the process. In this work, we der…
The Mathematical Structure of -Spin Amplitude Sum Rules
Margarita Gavrilova, Yuval Grossman, Stefan Schacht
We perform a systematic study of flavor amplitude sum rules with particular emphasis on -spin. This study reveals a rich mathematical structure underlying the sum rules…
Rotation-invariant observables as Density Matrix invariants
Margarita Gavrilova, Oleg Teryaev
It is shown that general dilepton angular distribution (with parity violating terms taking into account) in vector particle decays can be described through a set of five SO(3) rota…
