${\bar B} \to {\bar K}_2(1430) \ell^+ \ell^-$衰变分析

Analysis of the ${\bar B} \to {\bar K}_2(1430) \ell^+ \ell^-$ decay

S. Rai Choudhury, A. S. Cornell, Naveen Gaur

摘要:

我们提出了一个分析的衰变过程${\bar B} \to {\bar K}_2(1430) \ell^+ \ell^-$,这个过程中的所有功能的相关和充分研究的过程${\bar B} \to {\bar K}^*(890) \ell^+ \ell^-$,与理论上可比的分支比。差分衰减率以及向前向后的不对称性的工作,这些可能的右手耦合相关的$b \to s$辐射衰减的灵敏度也进行了研究。

英文摘要:

We present an analysis of the decay process ${\bar B} \to {\bar K}_2(1430) \ell^+ \ell^-$, where this process has all the features of the related and well investigated process ${\bar B} \to {\bar K}^*(890) \ell^+ \ell^-$, with theoretically comparable branching ratios. The differential decay rate as well as the forward-backward asymmetry are worked out, where the sensitivity of these to possible right-handed couplings for the related $b \to s$ radiative decay are also investigated.
