论文摘要
最近开发的$ b $ - mesegenesis方案预测，$ b $ erson的衰减在巴里昂和假设的深色抗体$ψ$中。我们建议一种计算最简单的独家衰减模式$ b^+\ topψ$的幅度的方法。考虑到两种$ b $ - 米斯生成的型号，我们通过将QCD轻圆单和使用Proton Light-Cone分布幅度应用了$ B \至P $ HADRONIC矩阵元素。我们将$ b^+\估计为pψ$衰变宽度，这是深色抗体的质量和有效耦合的函数。
The recently developed $B$-Mesogenesis scenario predicts decays of $B$ mesons into a baryon and hypothetical dark antibaryon $Ψ$. We suggest a method to calculate the amplitude of the simplest exclusive decay mode $B^+\to p Ψ$. Considering two models of $B$-Mesogenesis, we obtain the $B\to p$ hadronic matrix elements by applying QCD light-cone sum rules with the proton light-cone distribution amplitudes. We estimate the $B^+\to p Ψ$ decay width as a function of the mass and effective coupling of the dark antibaryon.
