“…[98], the authors studied the rapidity resummation improved B meson wave function and found that the resummation effect keeps the normalization of the B meson wave functions and strengths their convergent behavior at small spectator momentum. For more details about the wave functions of B/B s meson, one can see a new review paper [99] and references therein. We here still use the B/B s wave functions as defined in Refs.…”

In this short review, we present the current status about the theoretical and experimental studies for some important semileptonic decays of B/B s mesons. We firstly gave a brief introduction for the experimental measurements for B/B s → P (l + l − , l −ν l , νν) decays, the BaBar's R(D) and R(D * ) anomaly, the P ′ 5 deviation for B 0 → K * 0 µ + µ − decay. We then made a careful discussion about the evaluations for the relevant form factors in the light-cone QCD sum rule (LCSRs), the heavy quark effective theory, and the perturbative QCD factorization approach. By using the form factors calculated in the perturbative (pQCD) approach, we then calculate and show the pQCD predictions for the decay rates of many semileptonic decays of B/B s mesons. We also made careful phenomenological analysis for these pQCD predictions and found, in general, the following points: (a) For all the considered B/B s semileptonic decays, the next-to-leading order (NLO) pQCD predictions for their decay rates agree well with the data and those from other different theoretical methods; (b) For R(D) and R(D * ), the pQCD predictions agree very well with the data, the BaBar's anomaly of R(D ( * ) ) are therefore explained successfully in the standard model by employing the pQCD approach; and (c) We defined several new ratios R l,τ D and R l,τ Ds , they may be more sensitive to the QCD dynamics which controls the B/B s → (D ( * ) , D ( * ) s ) transitions than the old ratios, we therefore strongly suggest LHCb and the forthcoming Super-B experiments to measure these new ratios.

Distribution amplitudes of heavy mesons and quarkonia on the light front

et al. 2020

The ladder kernel of the Bethe–Salpeter equation is amended by introducing a different flavor dependence of the dressing functions in the heavy-quark sector. Compared with earlier work this allows for the simultaneous calculation of the mass spectrum and leptonic decay constants of light pseudoscalar mesons, the $$D_u$$ D u , $$D_s$$ D s , $$B_u$$ B u , $$B_s$$ B s and $$B_c$$ B c mesons and the heavy quarkonia $$\eta _c$$ η c and $$\eta _b$$ η b within the same framework at a physical pion mass. The corresponding Bethe–Salpeter amplitudes are projected onto the light front and we reconstruct the distribution amplitudes of the mesons in the full theory. A comparison with the first inverse moment of the heavy meson distribution amplitude in heavy quark effective theory is made.

“…Of course, one can write down H (0) a directly by using the initial and the final pion meson wave functions [10,[29][30][31][32][33] as given explicitly in Eqs. (10), (11) with the chiral mass of pion m 0π = 1.74 GeV:…”
