“…(3.10), we can calculate the hadronic matrix elements of the physical processes from (In this paper, the masses of 1 P 1 and 3 P 1 states introduced in Eq (3.12) are used only in solving the BS equations.) This approximation can also be found in the investigations of B → K 1 (1270, 1400)ll [52][53][54][55][56].…”

2420, 2430) or D * 2 (2460), are studied within the Standard Model. The hadronic matrix elements are evaluated in the Bethe-Salpeter approach and furthermore a discussion on the gauge-invariant condition of the annihilation hadronic currents is presented. Considering the penguin, box, annihilation, color-favored cascade and color-suppressed cascade contributions, the observables dBr/dQ 2 , A LP L , A F B and P L are calculated.

“…Refs. [35,36] indicate that for SUSY II in the case of muon channel C Q 1 and C Q 2 should not be greater than 0.5. In addition to this, in the absence of real experimental constraints on the FCNC modes in the case of tau channel, we may employ much larger Wilson coefficients (hence, SUSY effects) than we presented in Tables 2, and 3.…”

In this paper, we compare the branching ratio and rate difference of electron channel to muon channel of B → K * 0 (1430)ℓ + ℓ − and B → K * ℓ + ℓ − decays, where K * 0 (1430) is the p-wave scalar meson, in the supersymmetric models. MSSM with R parity is considered since considerable deviation from the standard model predictions can be obtained in B → X s ℓ − ℓ + . Taking C Q1 and C Q2 about one which is consistent with the B → K * µ + µ − rate at low dileptonic invariant mass region(1 ≤ q 2 ≤ 6GeV 2 ). It is found that, firstly, the B → K * 0 (1430)ℓ + ℓ − (ℓ = µ, τ ) decay is measurable at LHC, secondly, in comparison with B → K * ℓ + ℓ − decay a greater deviation in the B → K * 0 (1430)ℓ + ℓ − decay can be seen. Measurement of these observables for the semileptonic rare B → K * 0 (1430)ℓ + ℓ − , in particular, at low q 2 region can give valuable information about the nature of interactions within Standard Model or beyond.

In this work, the transition form factors are calculated for the semileptonic D (s) → Aℓ + ν where A = a1, b1, K1(1270, 1400), i.e., D + → a 0 1 (b 0 1 , K 0 1 )ℓ + ν, D 0 → a − 1 (b − 1 )ℓ + ν, and D + s → K 0 1 ℓ + ν in the frame work of the light-cone QCD sum rules (LCSR) approach up to the twist-3 distribution amplitudes (DAs). Since the masses of these axial vector mesons are comparable to the charm quark mass, we keep out in our calculations all terms including mA/mc in expansion of two-parton DAs. Branching ratio values are estimated for the semileptonic D (s) → Aℓν and nonleptonic D → K1(1270, 1400)π decays. A comparison is also made between our results and predictions of other methods and the existing experimental values.
