Finite width effects in nonleptonic D-decays
Girish Kumar, Sudheer Muhammad, Alexey A. Petrov
Many analyses of two-body non-leptonic decays of -mesons rely on flavor SU(3) symmetry relations and fits of experimental data of decays rates to extract the universal transitio…

Constraints on light dark sector particles from lifetime difference of heavy neutral mesons
Girish Kumar, Alexey A. Petrov
Heavy meson decays with missing energy in the final state offer interesting avenues to search for light invisible new physics such as dark matter (DM). In this context, we show tha…
