The mass spectrum and wave functions of the B c system
Journal of High Energy Physics, 2022 The spectrum and relativistic wave functions of B c system are investigated via solving the complete Salpeter equation. Emphases are put on the study of the partial waves of each J P state.

Journal of High Energy Physics, 2023 In light of the current discrepancies between the recent predictions based on QCD factorisation (QCDF) and the experimental data for several non-leptonic colour-allowed two-body B-meson decays, we obtain new determinations of the non-factorisable soft ...

Alternative treatment of the quark mass in the heavy quark expansion
Journal of High Energy Physics, 2023 The treatment of the quark mass plays an important role when it comes to increasing the precision of the predictions of the heavy quark expansion for inclusive heavy hadron decays.

Strange-quark mass effects in the B s meson’s light-cone distribution amplitude
Journal of High Energy Physics, 2023 We investigate the differences between the light-cone distribution amplitudes (LCDAs) of B s mesons and B q mesons (with q = u, d) induced by a non-vanishing strange-quark mass m s ≠ 0 (compared to m q ≃ 0).

Study of the b → dℓℓ transitions in the Standard Model and test of New Physics sensitivities
Journal of High Energy Physics, 2023 After incorporating all the available experimental data and the most up-to-date Lattice and light cone sum rule (LCSR) inputs on the form factors, we analyze the exclusive b → uℓν ℓ and b → dℓℓ decays simultaneously.

Standard Model predictions for lepton flavour universality ratios of inclusive semileptonic B decays
Journal of High Energy Physics, 2022 We present Standard Model predictions for lepton flavour universality ratios of inclusive B → X(c) ℓ ν ¯ ℓ $$ \ell {\overline{\nu}}_{\ell } $$ . For the ℓ = μ, e, these ratios are very close to unity as expected.

Complementary constraints on Zb b ¯ $$ Zb\overline{b} $$ couplings at the LHC
Journal of High Energy Physics, 2023 We propose a new strategy to probe the Z boson couplings to bottom and charm quarks at the LHC. In this work we mainly focus on the case of bottom quarks. Here, the Z boson is produced in association with two b-jets and decays to electrons or muons.

Experimental Physiology, EarlyView.Abstract Exercise and heat stress have been reported to independently provide benefits to brain health. We tested the hypothesis that 8 weeks of post‐exercise local heating, passive local heating only, or exercise training only improves cognitive performance compared to a control group.

Journal of High Energy Physics, 2017 We provide a systematic renormalization group formalism for the mass effects in the relation of the pole mass m Q pole and short-distance masses such as the M S ¯ $$ \overline{\mathrm{MS}} $$ mass m ¯ Q $$ {\overline{m}}_Q $$ of a heavy quark Q, coming ...

Revisiting semileptonic B meson decays at next-to-next-to-leading order
Journal of High Energy Physics, 2023 We compute next-to-next-to-leading order corrections to the semileptonic decay rate of B mesons for arbitrary values of the final-state quark mass. For the contribution with one massive quark in the final state, we extend the literature result and obtain
