论文摘要
在目前的工作中，我们研究了pion或Kaon引起的质子目标反应的$ p- $ wave魅力或诱人的陷阱。根据散射角度，以有效的Lagrangian方法评估了总横截面以及差分截面。我们的估计表明，横截面的大小很大程度上取决于模型参数，但是对于横截面比率几乎可以完全取消这种依赖性。这些独立模型的比率可以视为魅力地区重夸克限制有效性的良好标准，这有助于了解$ p $ - 波 - 波魅力和诱人的陷阱。
In the present work, we investigate the production of $P-$wave charmed or charmed-strange mesons in the pion or kaon induced reactions on a proton target. The total cross sections as well as the differential cross sections depending on the scattering angle are evaluated in an effective Lagrangian approach. Our estimations indicate that magnitude of the cross sections strongly depends on the model parameter but such dependence can be almost completely canceled for the cross section ratios. These model independent ratios can be taken as a good criterion of the validity of heavy quark limit in the charmed region, which is helpful to understand $P$-wave charmed and charmed-strange mesons.
