    "abstract": "Extended quantum mechanics using non-Hermitian, pseudo-Hermitian Hamiltonians\nis briefly reviewed. Supersymmetric regularizations, solvable simulations and\nlarge-N expansion techniques are recollected as suitable means for the study of\nnon-local quasi-particles. Their many-particle or even, perhaps, unstable and\ndecaying generalizations are also considered. Picking up the Klein-Gordon\nequation and its Feshbach-Villars\u0027 Hamiltonian for definiteness, we argue that\nthe PT symmetry might help to clarify experimental aspects of relativistic\nquantum mechanics.",
