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
