decays as probes of dark-matter scenarios of Belle II enhancement in decays

Alexander Berezhnoy, Wolfgang Lucha, Dmitri Melikhov

Recently, we have shown that the hypothesis of the dark-matter (DM) origin of the Belle II excess events in decays allows for a successful description of the data. The…

Triangle Feynman diagram in the timelike region

Mikhail A. Ivanov, Dmitri Melikhov, Silvano Simula

In Quantum Field Theory, triangle Feynman diagram is an analytic function of its variables, whose analytic structure is fully determined by the l…

On the Resonance Coupling and Width in Quantum Field Theory

Dmitri Melikhov

In quantum field theory, characteristics of resonances are related to self-energy diagrams, which are ultra-violet divergent and require renormalization. We demonstrate the proper…

Scrutinizing dark-matter scenarios with decays

Alexander Berezhnoy, Wolfgang Lucha, Dmitri Melikhov

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

Analysis of and 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 meson into some charged strange meson…

Nonfactorizable charming loops in exclusive FCNC decays

Dmitri Melikhov

We compare (i) nonfactorizable charm-quark loops in exclusive FCNC B-decays and (ii) three-particle contributions to the amplitude of semileptonic B-decay. Both amplitudes are give…
