复质量方案(CMS)为量子场论中处理不稳定粒子提供了一个一致的框架,并已成功地应用于各种回路计算。作为CMS在手征有效场论中的应用,我们考虑了类时区π介子的形状因子和罗珀共振的磁矩。
The complex-mass scheme (CMS) provides a consistent framework for dealing with unstable particles in quantum field theory and has been successfully applied to various loop calculations. As applications of the CMS in chiral effective field theory we consider the form factor of the pion in the time-like region and the magnetic moment of the Roper resonance.
