论文摘要
在手性有效场理论的框架中计算出领先的一环校正对增量共振的重力形式。对能量量张量的各种贡献和低能常数的重新归一化。使用小规模的扩展，获得静态数量的表达式，并通过数值计算重力形式的实际部分和虚构部分。
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.
