We present results for a renormalisation group analysis on
a Higgs Yukawa model in four-dimensional finite volume. In
particular, we perform perturbative calculation to idenfity the
one-loop scaling variable near a Gaussian fixed point.
We aim to fit the lattice field theoy simulation data with 2
degenerate fermion
The novel feature of this study is the fermionic contribution to the
finite-size scaling.
