چکیده

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 → Xsll. Taking CQ1 and CQ2 about one which is consistent with the B → K∗μ+μ− rate at low dileptonic invariant mass region(1 ≤ q2 ≤ 6GeV2). 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 q2 region can give valuable information about the nature of interactions within Standard Model or beyond.

Analysis of B → K ∗ 0 ( 1430 ) l + l − Decay in the Supersymmetric Models

In this paper, we study the branching ratios of B → K 0 (1430)l+l− decay, where K 0 (1430) being the p–wave scalar meson, in the supersymmetric models. The branching ratios are estimated when short and long distance effects are taken into account. It is found that the B → K 0 (1430)l+l− (l = μ, τ) decay is measurable at LHC. Measurement of these branching ratios for the semileptonic rare B → K ...

into fX(1300)K and J/ψK ∗ X(1430)

In light of the recent experimental results on decays B+ → fX(1300)K and B±(0) → J/ψK X (1430) from Belle, we study the B → P (V )S type decays, B±(0) → f0(1370)K and B±(0) → J/ψK 0 (1430), in comparison with the B → P (V )T type decays, B±(0) → f2(1270)K and B±(0) → J/ψK 2 (1430). We calculate the BRs for these decays by using the form factors obtained in the ISGW2 model [the improved version ...

Exclusive Radiative B Meson Decays

We have investigated exclusive, radiative B meson decays to charmless mesons (ρ, ω, φ, K(892), K 2 (1430)) in 9.7× 106 BB̄ decays accumulated with the CLEO detector. The B → K(892)γ branching fractions are determined to be B(B0 → K∗0(892)γ) = (4.55 +0.72 −0.68 ± 0.34)×10−5 and B(B+ → K∗+(892)γ) = (3.76 +0.89 −0.83 ± 0.28)×10−5. We have searched for CP asymmetry in B → K(892)γ decays and measure ...

l interaction in the minimal supersymmetric standard model and neutral Higgs decays

We extend previous analyses of the supersymmetric loop correction to the neutral Higgs couplings to include the coupling χj χ − k H 0 l . The analysis completes the previous analyses where similar corrections were computed for the τ̄ τH l , b̄bH 0 l , c̄cH 0 l and for t̄tH l couplings within the minimal supersymmetric standard model. The effective one loop Lagrangian is then applied to the computat...

We investigate the relations between the Kl3 and τ → Kπντ decays using the meson dominance approach. First, the experimental branching fractions (BF) for K e3 and K 0 e3 are used to fix two normalization constants (isospin invariance is not assumed). Then, the BF of τ → K(892)ντ is calculated in agreement with experiment. We further argue that the nonzero value of the slope parameter λ0 of the ...
