abstract

We leverage the CP violation in charged $B$ meson decays to generate the observed baryon asymmetry and dark matter at $\mathcal{O}(10 \text{ MeV})$ temperatures. We realize this in two scenarios: $B_c^+$ Mesogenesis and $B^+$ Mesogenesis. In the first, CP violating $B_c^\pm$ decays to $B^\pm$ mesons are followed by decays to dark and Standard Model baryons. In the second, CP violating $B^\pm$ decays to lighter charged mesons are accompanied by the latter's decays to dark and Standard Model leptons, which then scatter into the baryon asymmetry. $B_c^+$ Mesogenesis is actively being probed at Belle and LHCb, while $B^+$ Mesogenesis can be tested at colliders and sterile neutrino searches.

  1. Light-cone sum rules with $B$-meson distribution amplitudes for the $B\to p$ form factors in $B$-mesogenesis models

    hep-ph 2026-03 conditional novelty 7.0 of 10

    New light-cone sum-rule form factors predict B+→p + dark-antiproton rates and lower limits showing that Belle II/BaBar bounds must reach 10⁻⁸–10⁻⁷ for a decisive test of B-mesogenesis.

  2. Are Subleading Effects Really Subleading? $B$-Meson Decays in Mesogenesis

    hep-ph 2025-11 conditional novelty 6.0 of 10

    In B-Mesogenesis, formally subleading heavy-quark-expansion corrections to inclusive B decays exceed the leading free-quark decay for dark-fermion masses above about 2–3 GeV, limiting the reliable range of HQE-based c...

  3. Constraints on the mass of the dark antibaryon using $B_d\rightarrow \Lambda \psi_{DS}$ channel in light cone QCD

    hep-ph 2026-05 unverdicted novelty 5.0 of 10

    The mass ranges for the dark antibaryon ψ_DS are determined by deriving the B_d → Λ ψ_DS branching fraction via light-cone QCD sum rules and comparing it to BaBar and Belle experimental bounds.

  4. New Physics effects with right-handed neutrinos in semileptonic decay $B_c^+ \to B_s \mu^+ \nu_{\mu}$

    hep-ph 2024-11 conditional novelty 5.0 of 10

    Right-handed neutrino operators constrained by charm data are predicted to shift the lepton polarization asymmetry and convexity in B_c -> B_s mu nu away from the Standard Model, offering a way to distinguish new phys...
