- Production of Light Particles by Very Strong and Slowly Varying Magnetic Fields Giorgio Calucci Antonino Di Piazza Física, Astronomía y Matemáticas Particle creation Strong magnetic fields Field theory in curved spacetime The possibility that around some astrophysical objects there are non-static magnetic fields of enormous intensitysuggests that in these situations real particles may be produced. The slowness of the variation is compensatedby the huge intensity. The main issue is the production of e+ _e- pairs annihilating into photons andthe direct production of photons, as one of the concurrent process in the GRB (gamma ray bursts). Then somesimple effects due to the presence of the intense gravity are studied and finally a look is given to the productionof other kinds of particles. 2007 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46437519 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.2C Vol.37
