The decay $$B\rightarrow K+\nu +\bar{\nu }$$ B → K + ν + ν ¯ at Belle II and a massless bino in R-parity-violating supersymmetry

Abstract Recently, Belle II announced evidence for the decay $$B^+\rightarrow K^+ +\nu +\bar{\nu }$$ B + → K + + ν + ν ¯ at the $$3.5\,\sigma $$ 3.5 σ significance, and measured the corresponding decay branching ratio to be $$2.7\,\sigma $$ 2.7 σ above the Standard Model prediction. Here, we provide...
