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…
