Higgs-Yukawa Model in Chirally Invariant Lattice Field Theory

Figure 8

Susceptibility 𝜒_𝑚 at 𝜅=0.06 (a), 𝜅=0.00 (b), and the O(4) model (c) for various volumes. The curves are the result of a fit to (35). The right top boxes in (b) and (c) show 𝜒_𝑚 for the largest volumes. For the Higgs-Yukawa model, a volume-dependent shift of 𝑦_𝑐 towards 𝑦_𝑐^(𝐿=∞) can be observed. This shift is not observed in the O(4) model.
