Finite Size Corrections to qcotdelta for I=2 pipi near threshold

Description

fs.qcotdelta computes the finite size corrections to qcotdelta while fs.mpia0 computes the corresponding finite size corrections to Mpi a0 directly using the Gasser Leutwyler result from Mpi.

Usage

fs.mpia0(mps, fps, L)

Arguments

mps

pion mass as a scalar variable (must not be a vector)

fps

pion decay constant as a scalar variable (must not be a vector)

L

spatial lattice extent as a scalar variable (must not be a vector)

Value

returns a numeric value representing the finite size correction or in case of fs.a0 the corrected value for a0.
