fs.qcotdelta: Finite Size Corrections to \(q\cot\delta\) for I=2 \(\pi\pi\) near threshold

Description

fs.qcotdelta computes the finite size corrections to \(q\cot\delta\) while fs.mpia0 computes the corresponding finite size corrections to \(M_\pi a_0\) directly using the Gasser Leutwyler result from \(M_\pi\).

Usage

fs.qcotdelta(mps, L)

Arguments

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.

References

For the original formula see Eq. (31) from hep-lat/0601033
