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

Aritra Biswas, Alexander Khodjamirian, Ali Mohamed

New decay modes of $B$ -meson into a baryon and invisible dark antibaryon $I^¨$ are among the most distinctive signatures of the $B$ -mesogenesis scenario. We concentrate on the proto…

Nonlocal form factor of chromomagnetic penguin in $B \to K ℓ^{+} ℓ^{-}$ from QCD light-cone sum rules

T. Hurth, A. Khodjamirian, F. Mahmoudi +3

The branching fraction of the $B \to K ℓ^{+} ℓ^{-}$ decay has been measured recently by the LHC experiments, showing a deviation from theory predictions based on the Standard Model…

Non-perturbaitve effects in Higgs boson decays to electroweak vector bosons and photons

Alexander Khodjamirian, Kirill Melnikov, Arkady Vainshtein

We estimate the magnitude of the leading non-perturbative QCD corrections to the decays of the Higgs boson to the $I^^{3} Z$ and $I^^{3} I^^{3}$ final states. These corrections originate from th…

$D \to P ℓ^{+} ℓ^{-}$ decays assisted by QCD light-cone sum rules

Anshika Bansal, Alexander Khodjamirian, Thomas Mannel

We suggest a new method to analyse the rare $D_{(s)} \to P ℓ^{+} ℓ^{-}$ decays ( $P = I ¨ , K$ ), combining QCD light-cone sum rules (LCSR) with hadronic dispersion relations. As our main…
