Determination of the spin-dependent potentials with the multi-level algorithm

, 2005
The spin-dependent corrections to the static interquark potential are relevant to describing the fine and hyper-fine splittings of the heavy quarkonium spectra.

Power-enhanced leading-logarithmic QED corrections to B q → μ + μ −

Journal of High Energy Physics, 2019
We provide a systematic treatment of the previously discovered power- enhanced QED corrections to the leptonic decay B q → μ + μ − (q = d, s) in the frame- work of soft-collinear effective theory (SCET).

QED corrections in B ¯ → K ¯ ℓ + ℓ − $$ \overline{B}\to \overline{K}{\mathrm{\ell}}^{+}{\mathrm{\ell}}^{-} $$ at the double-differential level

Journal of High Energy Physics, 2020
We present a detailed analysis of QED corrections to B ¯ → K ¯ ℓ + ℓ − $$ \overline{B}\to \overline{K}{\mathrm{\ell}}^{+}{\mathrm{\ell}}^{-} $$ decays at the double-differential level.

Heavy quark physics in the covariant quark model.

, 2014
I give a short introduction to the covariant quark model and its applications to heavy quark physics. The special emphasis will be devoted to the semileptonic, rare and radiative decays of the $\Lambda_b$-baryon.

The dynamical diquark model: first numerical results

Journal of High Energy Physics, 2019
We produce the first numerical predictions of the dynamical diquark model of multiquark exotic hadrons. Using Born-Oppenheimer potentials calculated numerically on the lattice, we solve coupled and uncoupled systems of Schrödinger equations to obtain ...

The emergence of the ΔU = 0 rule in charm physics

Journal of High Energy Physics, 2019
We discuss the implications of the recent discovery of CP violation in two-body SCS D decays by LHCb. We show that the result can be explained within the SM without the need for any large SU(3) breaking effects.

How to employ B ¯ d 0 → J / ψ π η , K ¯ K $$ {\overline{B}}_d^0\to J/\psi \left(\uppi \eta, \overline{K}K\right) $$ decays to extract information on πη scattering

Journal of High Energy Physics, 2017
We demonstrate that dispersion theory allows one to deduce crucial information on πη scattering from the final-state interactions of the light mesons visible in the spectral distributions of the decays B ¯ d 0 → J / ψ π 0 η , K + K − , K 0 K ¯ 0 ...
