A comment on lepton mixing
Dimitrios Metaxas
Since right-handed neutrinos, if added to the Standard Model, have no gauge interactions, their kinetic terms can be mixed. I examine the related rotations of the gauge eigenstates…
Gauge independence of the physical fermion mass in the effective action of theories with radiative symmetry breaking
Dimitrios Metaxas
I consider an Abelian gauge theory, with a complex scalar field and massless, chiral fermions, in the limit where the couplings and the interactions induce radiative symmetry break…
Neutrino oscillations in gravitational and cosmological backgrounds
George Koutsoumbas, Dimitrios Metaxas
We use the eikonal approximation in order to calculate the additional phase shift between two neutrino mass eigenstates during their propagation in a background of gravitational wa…
Effects of the cosmological expansion on the bubble nucleation rate for relativistic first-order phase transitions
Dimitrios Metaxas
I calculate the first corrections to the dynamical pre-exponential factor of the bubble nucleation rate for a relativistic first-order phase transition in an expanding cosmological…
An application of the renormalization group to the calculation of the vacuum decay rate in flat and curved space-time
D. Metaxas
I show that an application of renormalization group arguments may lead to significant corrections to the vacuum decay rate for phase transitions in flat and curved space-time. It c…
Hard thermal loops with a background plasma velocity
D. Metaxas
I consider the calculation of the two and three-point functions for QED at finite temperature in the presence of a background plasma velocity. The final expressions are consistent…
