前向色散关系约束下的π-K介子散射振幅可达1.6 GeV

The pion-kaon scattering amplitude constrained with forward dispersion relations up to 1.6 GeV

J. R. Pelaez, A. Rodas

摘要:

在这项工作中,我们提供了简单而精确的参数化现有的$πK$散射数据从阈值高达1.6 GeV,这是约束,以满足前向色散关系,以及三个额外的阈值和规则。我们还提供了出现在弹性散射的阈值参数和共振极点的唯象值。

英文摘要:

In this work we provide simple and precise parameterizations of the existing $πK$ scattering data from threshold up to 1.6 GeV, which are constrained to satisfy forward dispersion relations as well as three additional threshold sum rules. We also provide phenomenological values of the threshold parameters and of the resonance poles that appear in elastic scattering.
