自旋1/2单粲重子的强CP破坏

Strong CP violation in spin-1/2 singly charmed baryons

Y. Ünal, Ulf-G. Meißner

摘要:

本文计算了由QCD $θ$项产生的自旋为1/2扇区的粲重子的CP破坏形状因子$F_3$和相应的电偶极矩。我们在协变重子手征微扰理论的框架下,在扩展的质量壳层重整化方案中工作,直到手征展开中的次主导阶。

英文摘要:

We report on the calculation of the CP-violating form factor $F_3$ and the corresponding electric dipole moment for charmed baryons in the spin-1/2 sector generated by the QCD $θ$-term. We work in the framework of covariant baryon chiral perturbation theory within the extended-on-mass-shell renormalization scheme up to next-to-leading order in the chiral expansion.
