Chiral Perturbation Theory at Finite Volume and/or with Twisted Boundary Conditions
Abstract
In this talk we discuss a number of ChPT calculations relevant for lattice QCD. These include the finite volume corrections at twoloop order for masses and decay constants. The second part is about hadronic vacuum polarization where we present the twoloop ChPT estimate for the disconnected and strange quark contributions. We also present the finite volume corrections at twoloop order. The final part is the oneloop finite volume with twisted boundary conditions contribution to f+(q2) and the full Kℓ3 amplitude.
