fs.a0 | R Documentation |
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.
fs.a0(a0, mps, L)
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) |
returns a numeric value representing the finite size correction or
in case of fs.a0
the corrected value for a0.
