On limitation of mass spectrum in non-Hermitian $\mathcal{P}\mathcal{T}$-symmetric models with the ${\gamma }_5$-dependent mass term

V. N. Rodionov

The modified Dirac equations for the massive particles with the replacement of the physical mass $m$ with the help of the relation $m\to m_1+{\gamma }_5{m}_2$ are investigated. It…
