fs.a0: Finite Size Corrections to qcotdelta for I=2 pipi near...

Description Usage Arguments Value Author(s) References Examples

View source: R/fs.mpia0.R

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

1
fs.a0(a0, mps, L)

Arguments

a0

scattering length at finite L

mps

pion mass 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.
