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…
