高能和低能光子的衰变

Decay of photon with high as well as low energy

Indranath Bhattacharyya

摘要:

考虑了光子在磁场作用下的衰减。结果表明,当光子能量大于1 MeV时,光子能衰变成电子-正电子对,而当光子能量小于1 MeV时,光子能衰变成中微子-反中微子对。计算了这两个过程的衰变率。所有可能的费曼图被考虑到构建的矩阵元素的过程。在第二个过程中,所有三种类型的中微子都被考虑。这些过程的意义进行了简要讨论。

英文摘要:

The decay of photon by the influence of magnetic field is considered. It is shown here that if the photon energy is grater than 1 MeV then photon can decay electron positron pair, but if it remains below 1 MeV then photon decays into neutrino antineutrino pair. The decay rates for both of the processes are calculated. All possible Feynman diagrams are taken into account to construct the matrix element for either of the processes. In the second process all three type of neutrinos are considered. The significance of these processes are discussed briefly.
