QCD求和规则中B -> K_0*(1430)l^+ l^-衰变的分析

Analysis of rare (B -> K_0*(1430) l^+ l^- decay) within QCD sum rules

T. M. Aliev, K. Azizi, M. Savci

摘要:

B -> K_0 ~*(1430)1 ^+1 ^- $ decay) 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,mu)) decay is measurable at LHC. Measurement of these branching ratios for the semileptonic rare (B -> K_0*(1430) l^+ l^-$衰变的形状因子可以提供有关标量介子(K_0 ~*(1430))性质的有价值的信息。

英文摘要:

Form factors of rare (B -> K_0*(1430) l^+ l^-$ decay) 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,mu)) decay is measurable at LHC. Measurement of these branching ratios for the semileptonic rare (B -> K_0*(1430) l^+ l^-$ decay) can give valuable information about the nature of scalar meson (K_0* (1430)).
