Classical cross sections for relativistic spinning particles Bona, Carles Fustero, X. (Xavier) Verdaguer Oms, Enric, 1950- Electromagnetisme Gravitació Interaccions febles (Física nuclear) Partícules (Física nuclear) Electromagnetism Gravitation Weak interactions (Nuclear physics) Particles (Nuclear physics) We propose a definition of classical differential cross sections for particles with essentially nonplanar orbits, such as spinning ones. We give also a method for its computation. The calculations are carried out explicitly for electromagnetic, gravitational, and short-range scalar interactions up to the linear terms in the slow-motion approximation. The contribution of the spin-spin terms is found to be at best 10-6 times the post-Newtonian ones for the gravitational interaction. 2010-05-06T09:54:37Z 2010-05-06T09:54:37Z 1983 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 0556-2821 https://hdl.handle.net/2445/12400 79587 eng Reproducció digital del document publicat en format paper, proporcionada per PROLA i http://dx.doi.org/10.1103/PhysRevD.28.317 Physical Review D, 1983, vol. 28, núm. 2, p. 317-324 http://dx.doi.org/10.1103/PhysRevD.28.317 (c) The American Physical Society, 1983 info:eu-repo/semantics/openAccess 8 p. application/pdf The American Physical Society Articles publicats en revistes (Física de la Matèria Condensada)
