Three exceptions to the Grossman-Nir bound
Abstract We show that the Grossman-Nir (GN) bound, Br(K L → π 0 ν ν ¯ $$ {\pi}^0\nu \overline{\nu} $$ ) ≤ 4.3 Br(K + → π + ν ν ¯ $$ {\pi}^{+}\nu \overline{\nu} $$ ), can be violated in the presence of light new physics with flavor violating couplings. We construct three sample models in which the GN...
