Abstract:It is proposed that T violation in physics, as well as the masses of electron and View the MathML source quarks, arise from a pseudoscalar interaction with a new spin 0 field τ(x), odd in P and T, but even in C. This interaction contains a factor iγ5 in the quark and lepton Dirac algebra, so that the full Hamiltonian is View the MathML source conserving; but by spontaneous symmetry breaking, the new field τ(x) has a nonzero expectation value left angle bracketτright-pointing angle bracket≠0 that breaks P and T symmetry. Oscillations of τ(x) about its expectation value produce a new particle, the “timeon”. The mass of timeon is expected to be high because of its flavor-changing properties.The main body of the paper is on the low energy phenomenology of the timeon model. As we shall show, for the quark system the model gives a compact three-dimensional geometric picture consisting of two elliptic plates and one needle, which embodies the 10 observables: six quark masses, three Eulerian angles View the MathML source and the Jarlskog invariant of the CKM matrix.For leptons, we assume that the neutrinos do not have a direct timeon interaction; therefore, the lowest neutrino mass is zero. The timeon interaction with charged leptons yields the observed nonzero electron mass, analogous to the up and down quark masses. Furthermore, the timeon model for leptons contains two fewer theoretical parameters than observables. Thus, there are two testable relations between the three angles View the MathML source and the Jarlskog invariant of the neutrino mapping matrix.
