轴向$N\toΔ(1232)$跃迁的手征微扰理论研究

L. S. Geng, J. Martin Camalich, L. Alvarez-Ruso, M. J. Vicente Vacas

摘要:

在协变重子手征微扰理论中,我们对轴向核子到δ(1232)($N\toΔ$)跃迁的形状因子进行了理论研究,其中$Δ$场的非物理自旋1/2分量是解耦的.

英文摘要:

We have performed a theoretical study of the axial Nucleon to Delta(1232) ($N\toΔ$) transition form factors up to one-loop order in covariant baryon chiral perturbation theory within a formalism in which the unphysical spin-1/2 components of the $Δ$ fields are decoupled.
