The radiative leptonic decays Ds → μνμγ and D → μνμγ are investigated at the tree level within the relativistic independent quark model based on the confining potential in the scalar–vector harmonic form. The branching ratios for these decays in the vanishing lepton mass limit are obtained as ℬr(Ds → μνμγ) = 4.94×10-4 and ℬr(D → μνμγ) = 3.34×10-5, which includes the contributions of the internal bremsstrahlung and structure dependent diagrams at the level of the quark constituents. Finally, the photon energy spectra as predicted here is found to be symmetric about the peak value of the photon energy at [Formula: see text].

In this work, we study the radiative leptonic decays of [Formula: see text] and [Formula: see text] mesons in the Standard Model (SM) and two-Higgs-doublet-model (2HDM) Type II. The results are obtained using the factorization procedure, and the contribution of the order [Formula: see text] is included. The numerical results are calculated using the wave function obtained in relativistic potential model. As a result, the decay mode [Formula: see text] is found to be sensitive to the effect of the charged Higgs boson. Using the constraint on the free parameters of 2HDM given in previous works, we find the contribution of the charged Higgs boson in the decay mode [Formula: see text] can be as large as about 13%.

In this article, recent ALICE measurements of the RAA and v2 of electrons at mid-rapidity (|y|<0.6) and muons at forward rapidity (2.5<y<4), from semi-leptonic decays of heavy-flavour hadrons in Pb–Pb collisions at [see formula in PDF] = 5.02 TeV are shown. The results of D-tagged jet production cross-section in pp collisions at √s =7 TeV are presented. In addition, the azimuthal correlation of D mesons with charged particles in p–Pb collisions at [see formula in PDF] = 5.02 TeV, and electrons from semi-leptonic decays of heavyflavour hadrons with charged particles in p–Pb and Pb–Pb collisions at [see formula in PDF] = 5.02 TeV are reported.

In this work, we study the radiative leptonic decays of B-, D-and [Formula: see text], including both the short-distance and long-distance contributions. The short-distance contribution is calculated by using the relativistic quark model, where the bound state wave function we used is that obtained in the relativistic potential model. The long-distance contribution is estimated by using vector meson dominance model.
