有效场论中$Δ(1232)$区域的PDMATHAAA散射

$πN$ Scattering in the $Δ(1232)$ Region in an Effective Field Theory

Bingwei Long, U. van Kolck

摘要:

我们发展了一个广义的重子手征微扰理论来描述π介子核子散射的运动域,从阈值连续延伸到δ-等压线峰。$P$波相移被用来说明这个框架。我们还比较了我们的方法与文献中的那些有关的三角洲共振。

英文摘要:

We develop a generalized version of heavy-baryon chiral perturbation theory to describe pion-nucleon scattering in a kinematic domain that extends continuously from threshold to the delta-isobar peak. The $P$-wave phase shifts are used to illustrate this framework. We also compare our approach with those in the literature that concern the delta resonance.
