Scrutininzing Dark-Matter Scnearios with B *> (K,K* )*n^-*n Decays / A.Berezhnoy, W.Lucha, D.Melikhov. – Text : electronic // Universe. – 2025. – Vol. 11, No. 12. – P. 385. – URL: https://doi.org/10.3390/universe11120385. – Bibliogr.: 49.
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–antineutrino pairs might be offered by additional contributions of dark matter fermion–antifermion pairs. Assuming the excessive missing-energy events to be mediated by a (generic) scalar or vector boson, a simultaneous inspection of both the missing energy B decays into a pseudoscalar K meson or a vector 𝐾∗ meson enables to gain information on the nature of any boson relating the standard-model and dark-matter sectors, irrespective of (unknown) dark-sector details. Upon availability of indispensable experimental data, most prominent among such insights might be the identification of the mediator spin from the differential B-meson decay widths.
