چکیده

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 0 (1430)l+l−, in particular, at low q2 region can give valuable information about the nature of interactions within Standard Model or beyond. e-mail: [email protected] e-mail: [email protected] e-mail: [email protected]

0 ( 1430 ) l + l − decays in the Supersymmetric Models

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 ...

0(1430)ll decay within QCD sum rules

Form factors of rare B → K 0 (1430)l+l− decay are calculated within three–point QCD sum rules, with K 0 (1430) being the p–wave scalar meson. The branching ratios are estimated when only short, as well as short and long distance effects, are taken into account. It is obtained that the B → K 0 (1430)l+l− (l = e, μ) decay is measurable at LHC. Measurement of these branching ratios for the semilep...

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 ...

Hadronic mass spectrum analysis of D + → K − π + µ + ν decay and measurement

We present a Kπ mass spectrum analysis of the four-body semileptonic charm decay D+ → K−π+μ+ν in the range of 0.65 GeV/c2 < mKπ < 1.5 GeV/c 2. We observe a non-resonant contribution of 5.30 ± 0.74 − 0.96% with respect to the total D+ → K−π+μ+ν decay. For the K∗(892)0 resonance, we obtain a mass of 895.41 ± 0.32 − 0.43 MeV/c 2, a width of 47.79 ± 0.86 − 1.06 MeV/c 2, and a BlattWeisskopf damping...

Neutralino decay of MSSM neutral Higgs bosons

We compute the one loop corrected effective Lagrangian for the neutralino-neutralinoneutral Higgs interactions χlχ 0 kH 0 m. The analysis completes the previous analyses where similar corrections were computed for the f̄ fH m couplings, where f stands for Standard Model quarks and leptons and for the chargino-chargino-neutral Higgs couplings χ+l χ − k H 0 m within the minimal supersymmetric stan...
