电子的引力形状因子D(t)

The gravitational form factor D(t) of the electron

Andreas Metz, Barbara Pasquini, Simone Rodini

摘要:

电子-引力子相互作用可以用QED能量动量张量的引力形状因子来描述。在这里,我们专注于形状因子D(t),我们检查它的属性和解释的内力在QED单圈精度。我们通过将能量动量张量的电子和光子部分的贡献分开来进行计算。我们还研究了非零光子质量的情况。进一步讨论了与强子束缚态形状因子D(t)的异同。

英文摘要:

The electron-graviton interaction can be described in terms of the gravitational form factors of the QED energy momentum tensor. Here we focus on the form factor D(t), and we examine its properties and its interpretation in terms of internal forces at one-loop accuracy in QED. We perform the calculation by keeping separate the contributions due to the electron and the photon parts of the energy momentum tensor. We also study the case of a nonzero photon mass. Furthermore, we discuss similarities with and differences to the form factor D(t) of hadronic bound states.
