Higgs-Yukawa Model in Chirally Invariant Lattice Field Theory

Table 2

Results of a correlated fit to the susceptibility according to (35) where the last column indicates the fit interval. The parameter 𝑇 stands either for 𝑦 in the Higgs-Yukawa model or for 𝜅 in the O(4) model. Since no volume-dependent shift can be observed in the O(4) model for 𝜒_𝑚, the parameters 𝐶 and 𝑏 have not been fitted here. All quoted errors are statistical only.
