The presence or absence of sectors depends on the values of rest masses. Some aspects of the canonical quantization are described. The model could be interpreted as a bigravity model in one dimension.9 p.application/pdfeng(c) American Physical Society, 2014Física nuclearSimetria (Física)Camps de galga (Física)Nuclear physicsSymmetry (Physics)Gauge fields (Physics)Dynamical sectors of a relativistic two particle modelinfo:eu-repo/semantics/article6401572014-05-21info:eu-repo/semantics/openAccess
