由非常强且缓慢变化的磁场产生轻粒子

Production of light particles by very strong and slowly varying magnetic fields

Giorgio Calucci, Antonino Di Piazza

摘要:

某些天体周围可能存在强度极大的非静态磁场,这表明在这些情况下可能产生真实的粒子。变化的缓慢被巨大的强度所补偿。作为伽玛暴(伽马射线暴)的并发过程之一,主要问题是e ~+,e ~-对湮灭为光子的产生和光子的直接产生。然后研究了由于强引力的存在而产生的一些简单效应,最后展望了其他种类粒子的产生。

英文摘要:

The possibility that around some astrophysical objects there are non-static magnetic fields of enormous intensity suggests that in these situations real particles may be produced. The slowness of the variation is compensated by the huge intensity. The main issue is the production of e+,e- pairs annihilating into photons and the direct production of photons, as one of the concurrent process in the GRB (gamma ray bursts). Then some simple effects due to the presence of the intense gravity are studied and finally a look is given to the production of other kinds of particles.
