REGGE POLES FOR z<sup>-4</sup> REPULSIVE POTENTIAL

Abstract

摘要 对z-4排斥位势证明了:(1)当|λ|→∞,|argλ|<π/2-ε时,S矩阵元S(λ,k)→1。(2)当|λ|→∞时,有无穷多个极点存在于虚轴的小角邻域内,并且这些极点的实部和虚部同时趋于∞,因此通常的双色散关系不成立。 Abstract It is proved that the S matrix element S(λ, k) for the z-4 repulsive potential → 1 as |λ|→∞ in the sector 0 ≤| argλ | <π/2-ε and that it has infinitely many Reggepoles in a small angle neighbourhood of the imaginary axis with their real and imaginary parts approaching ∞ simultaneously. Ordinary double dispersion relation does not hold in this case. 作者及机构信息 戴元本 1. 中国科学院 Authors and contacts DAI YUAN-BEN 1. 中国科学院 参考文献 [1] 施引文献
