Scrutinizing dark-matter scenarios with $B \to (K, K^{*}) ν ˉ ν$ decays

Alexander Berezhnoy, Wolfgang Lucha, Dmitri Melikhov

Conceivable explanations of Belle-II measurements of a (surprising) excess of missing-energy decays of the $B$ meson to the $K$ meson not covered by standard-model neutrino-antineu…

Analysis of $B \to K M_{X}$ and $B \to K^{*} M_{X}$ decays in scalar- and vector-mediator dark-matter scenarios

Alexander Berezhnoy, Wolfgang Lucha, Dmitri Melikhov

The surprising excess of missing-energy events far beyond all standard-model expectations in the weak decays of the charged ground-state $B^{+}$ meson into some charged strange meson…

Probing vector- vs scalar-mediator dark-matter scenarios in $B \to (K, K^{*}) M_{X}$ decays

Alexander Berezhnoy, Wolfgang Lucha, Dmitri Melikhov

Within the hypothesis of the dark-matter origin of the excess in $B \to K M_{X}$ decays over the standard-model expectation, observed by Belle-II, we show that: (i) Scalar- and vector…

Analysis of $q_{rec}^{2}$ -distribution for $B \to K M_{X}$ and $B \to K^{*} M_{X}$ decays in a scalar-mediator dark-matter scenario

Alexander Berezhnoy, Wolfgang Lucha, Dmitri Melikhov

We demonstrate that the scalar-mediator dark-matter scenario is consistent with the experimental data on the decay $B \to K M_{X}$ and provides a good description of the shape of the…
