摘要:

在手征有效场论的框架下计算了δ共振引力形状因子的主导单圈修正。计算了能量动量张量和低能常数重整化的各种贡献。利用小尺度展开,得到了静态量的表达式,并数值计算了引力形状因子的实部和虚部。

英文摘要:

The leading one-loop corrections to the gravitational form factors of the delta resonance are calculated in the framework of chiral effective field theory. Various contributions to the energy-momentum tensor and the renormalization of the low-energy constants are worked out. Using the small scale expansion, expressions for static quantities are obtained and the real and imaginary parts of the gravitational form factors are calculated numerically.
