    Notes: Abstract The localization problem of relativistic particles is studied, considering that an elementary spin-1/2 particle of nonvanishing mass actually corresponds to an extended body. The role of non-Hermitian operators in describing such a system is discussed and it is pointed out that the localization of such a system is linked to the global conservation of fermion number given by the “internal helicity” of such a system. The localization region is then determined by means of imprimitivity systems for particular representations of the de Sitter groupS0(4, 1).
