增强校正波函数的强衰变

Strong decays with the boost-corrected wave functions

Yu. A. Simonov

摘要:

强衰变几率的计算使用洛伦兹收缩波函数的衰变产物,确定在任意动力学计划与瞬时相互作用。结果表明,衰变宽度获得了一个由收缩系数$C_m(s)$定义的附加因子,对于两体等质量衰变,该因子为$C^2_m(s)= 4m^2/s$,$s= E^2$。将得到的衰减宽度与实验数据进行比较,其中特别地,$ρ(770),ρ(1450) $衰减数据需要宽度的附加$1/s$依赖性来拟合数据。强子衰变和散射的动力学的重要后果进行了简短的讨论。

英文摘要:

Strong decay probabilities are calculated using the Lorentz contracted wave functions of decay products, determined in the arbitrary dynamical scheme with the instantaneous interaction. It is shown that the decay width obtains an additional factor defined by the contraction coefficient $C_m(s)$, which for two-body equal mass decays is $C^2_m(s)= 4m^2/s$ , $s= E^2$. The resulting decay widths are compared to the experimental data, where in particular the $ρ(770),ρ(1450) $ decay data require an additional $1/s$ dependence of the width to fit the data. Important consequences for the dynamics of hadron decays and scattering are shortly discussed.
