Chapter 22 Smearing

in order to have a field with the same quantum number of $\phi_0$ we create the smeared field $$S_{n+1}(x,p)=e^{i\rho S_n(x,p)}S_n(x,p)\,\quad\quad \mbox{with}\quad\quad S_0=\phi_0\,,$$ and $n=5$ and $\rho=0.2$. Then we compute the correlator $$\langle S_n(0,p=0) S_n(t,p=0) \rangle$$

E1_0(L24T32) = 0.129285(59) $\chi^2/dof=$ 0.039038
