Towards a unique formula for neutrino oscillations in vacuum
M. Beuthe
We show that all correct results obtained by applying quantum field theory to neutrino oscillations can be understood in terms of a single oscillation formula. In particular, the m…

Field theory approach to K0-K0bar and B0-B0bar systems
M. Beuthe, G. Lopez Castro, J. Pestieau
Quantum field theory provides a consistent framework to deal with unstable particles. We present here an approach based on field theory to describe the production and decay of unst…

Behaviour of the Absorptive Part of the W Electromagnetic Vertex
M. Beuthe, R. Gonzalez Felipe, G. Lopez Castro +1
The absorptive part of the vertex induced by massive fermion loops is considered for different kinematical configurations. We show that the axial part of this vertex is diffe…
