Beghetto, D. [UNESP]Hoff Da Silva, J. M. [UNESP]2018-12-112018-12-112017-08-01EPL, v. 119, n. 4, 2017.1286-48540295-5075http://hdl.handle.net/11449/170390The so-called Inomata-McKinley spinors are a particular solution of the non-linear Heisenberg equation. In fact, free linear massive (or massless) Dirac fields are well known to be represented as a combination of Inomata-McKinley spinors. More recently, a subclass of Inomata-McKinley spinors was used to describe neutrino physics. In this paper we show that Dirac spinors undergoing this restricted Inomata-McKinley decomposition are necessarily of the first type, according to the Lounesto classification. Moreover, we also show that these type-one subclass spinors have not an exotic counterpart. Finally, implications of these results are discussed, regarding the understanding of the spacetime background topology.engArtigo10.1209/0295-5075/119/40006Acesso aberto2-s2.0-850344278412-s2.0-85034427841.pdf
