Finite volume effects for the pion mass at two loops
Gilberto Colangelo, Christoph Haefeli
We evaluate the pion mass in finite volume to two loops within Chiral Perturbation Theory. The results are compared with a recently proposed extension of the asymptotic formula of…
The pion and proton mass in finite volume
Gilberto Colangelo, Andreas Fuhrer, Christoph Haefeli
We calculate the finite volume effects for the pion and nucleon mass. For the pion mass we present the results of a full two-loop calculation in chiral perturbation theory. The out…
The pion mass in finite volume to two loops

We evaluate the pion mass in finite volume to two loops within Chiral Perturbation Theory. The results are compared with a recently proposed extension of the asymptotic formula of…
An asymptotic formula for the pion decay constant in a large volume
Gilberto Colangelo, Christoph Haefeli
We derive an asymptotic formula a la Luscher for the finite volume correction to the pion decay constant: this is expressed as an integral over the < 3 π| A_μ|0 > amplitude after p…
