چکیده
The study of factorization in linearized gravity is extended to the graviton scattering processes with an electron for the massive vector boson productions such as ge → Ze and ge → Wνe. It is shown that every transition amplitude is completely factorized due to gravitational gauge invariance and Lorentz invariance. Also the explicit values of vector boson polarizations are obtained. PACS number(s) : 04.60.+n, 12.25.+e, 13.88.+e In the standard gauge theory every four-body Born amplitude with a massless gauge boson as an external particle has been well known to be factorizable [1–4] into one factor which depends only on charge or other internal-symmetry indices and the other factor which depends on spin or polarization indices.

We found an infinite number of potentials surrounding 2d black hole. According to the transmission T and reflection R coefficients for scattering of string fields off 2d black hole, we can classify an infinite number of potentials into three : graviton-dilaton, tachyon and the other types. We suggest that the discrete states from all the Virasoro levels be candidates for new potentials (modes).

The leading contribution of the light-by-light scattering effects to g-factor of a bound electron is derived. The corresponding amplitude is expressed in terms of low-energy Delbrück scattering of a virtual photon. The result reads ∆g = (7/216)α(Zα)5 .

The study of factorization in the linearized gravity is extended to the graviton scattering processes with a massive scalar particle, with a massless vector boson and also with a graviton. Every transition amplitude is shown to be completely factorized and the physical implications of their common factors are discussed.
