Neutrino Helicity Reversal and Fundamental Symmetries
U. D. Jentschura, B. J. Wundt
A rather elusive helicity reversal occurs in a gedanken experiment in which a massive left-handed Dirac neutrino, traveling at a velocity u < c, is overtaken on a highway by a spee…
From Generalized Dirac Equations to a Candidate for Dark Energy
U. D. Jentschura, B. J. Wundt
We consider extensions of the Dirac equation with mass terms m1+i*gamma5*m2 and i*m_1+gamma*m2. The corresponding Hamiltonians are Hermitian and pseudo-Hermitian ("gamma5 Hermitian…
Localizability of Tachyonic Particles and Neutrinoless Double Beta Decay
U. D. Jentschura, B. J. Wundt
The quantum field theory of superluminal (tachyonic) particles is plagued with a number of problems, which include the Lorentz non-invariance of the vacuum state, the ambiguous sep…
Pseudo-Hermitian Quantum Dynamics of Tachyonic Spin-1/2 Particles
U. D. Jentschura, B. J. Wundt
We investigate the spinor solutions, the spectrum and the symmetry properties of a matrix-valued wave equation whose plane-wave solutions satisfy the superluminal (tachyonic) dispe…
Reparameterization invariance of NRQED self-energy corrections and improved theory for excited D states in hydrogenlike systems
B. J. Wundt, U. D. Jentschura
Canonically, the quantum electrodynamic radiative corrections in bound systems have been evaluated in photon energy regularization, i. e. using a noncovariant overlapping parameter…
