Present status of radiative and rare kaon decays [PDF]

open access: yesEPJ Web of Conferences, 2022
I will review recent developments in rare and radiative kaon decays from the theory side, with emphasis on those modes that are actively analyzed by the experimental collaborations.

B → D1(2420) and B → D 1 ′ $$ {\mathrm{D}}_1^{\prime } $$ (2430) form factors from QCD light-cone sum rules

open access: yesJournal of High Energy Physics, 2022
We perform the first calculation of form factors in the semileptonic decays B → D 1(2420)ℓν ℓ and B → D 1 ′ $$ {D}_1^{\prime } $$ (2430)ℓν ℓ using QCD light-cone sum rules (LCSRs) with B-meson distribution amplitudes. In this calculation the c-quark mass

B → D 0 ∗ $$ B\to {D}_0^{\ast } $$ and B s → D s 0 ∗ $$ {B}_s\to {D}_{s0}^{\ast } $$ form factors from QCD light-cone sum rules

open access: yesJournal of High Energy Physics, 2023
We present the first application of QCD light-cone sum rules (LCSRs) with B (s)-meson distribution amplitudes to the B s → D s 0 ∗ $$ {B}_{(s)}\to {D}_{(s)0}^{\ast } $$ form factors, where D s 0 ∗ $$ {D}_{(s)0}^{\ast } $$ is a charmed scalar meson.

New sum rules for the B c → J/ψ form factors

open access: yesJournal of High Energy Physics, 2023
We derive new sum rules for the form factors of the B c → J / ψ ℓ ν ¯ ℓ $$ {B}_c\to J/\psi \ell {\overline{\nu}}_{\ell } $$ semileptonic transitions, employing the vacuum-to-B c correlation function of the J/ψ-interpolating and b → c weak currents.

Feynman integral reduction using Gröbner bases

open access: yesJournal of High Energy Physics, 2023
We investigate the reduction of Feynman integrals to master integrals using Gröbner bases in a rational double-shift algebra Y in which the integration-by-parts (IBP) relations form a left ideal.

Impact of background effects on the inclusive V cb determination

open access: yesJournal of High Energy Physics, 2021
The determination of the CKM element V cb from inclusive semileptonic b → cℓ ν ¯ $$ \overline{\nu} $$ decays has reached a high precision thanks to a combination of theoretical and experimental efforts.

B-meson decay into a proton and dark antibaryon from QCD light-cone sum rules

open access: yesPhysics Letters B, 2022
The recently developed B-Mesogenesis scenario predicts decays of B mesons into a baryon and hypothetical dark antibaryon Ψ. We suggest a method to calculate the amplitude of the simplest exclusive decay mode B+→pΨ. Considering two models of B-Mesogenesis,
