NNLO Positivity Bounds on ChPT for a General Number of Flavours
Benjamin Alvarez, Johan Bijnens, Mattias Sjö
We present positivity bounds, derived from the principles of analyticity, unitarity and crossing symmetry, that constrain the low-energy constants of chiral perturbation theory. Bo…
NNLO Positivity Bounds on Chiral Perturbation Theory for a General Number of Flavours
Benjamin Alvarez, Johan Bijnens, Mattias Sjö
We present positivity bounds, derived from the principles of analyticity, unitarity and crossing symmetry, that constrain the low-energy constants of chiral perturbation theory. Bo…
Ultraviolet Renormalisation of a quantum field toy model I
Benjamin Alvarez, Jacob Schach Møller
We consider a class of Hamiltonians describing a fermion field coupled to a boson field. The interaction kernels are assumed bounded in the fermionic momentum variable and decaying…
Hamiltonian models of interacting fermion fields in Quantum Field Theory
Benjamin Alvarez, Jérémy Faupin, Jean-Claude Guillot
We consider hamiltonian models representing an arbitrary number of spin fermion quantum fields interacting through arbitrary processes of creation or annihilation of particle…
Scattering Theory for Mathematical Models of the Weak Interaction
Benjamin Alvarez, Jérémy Faupin
We consider mathematical models of the weak decay of the vector bosons into leptons. The free quantum field hamiltonian is perturbed by an interaction term from the stand…
