\(B \to {{K}^{{(*)}}}\nu \bar {\nu }\) Decays: Data and Theoretical Predictions

In this paper we compare data from Belle II and BaBar with available results of theoretical approaches for \(B \to {{K}^{{(*)}}}\nu \bar {\nu }\) decays. The theoretical predictions for \({{B}^{ + }} \to {{K}^{ + }}\nu \bar {\nu }\) are lower than experimental data. This may indicate on the possibility of new physics effects in this decay.
