Detailed Description

Two-point correlator for Wilson-type fermions with SF BC.

  • Evaluate the axial current - pseudo scalar two point funciton fA, fA'.
  • Evaluate the pseudo scalar - pseudo scalar two point funciton fP, fP'
  • These two point functions are used to evaluate the PCAC mass and $\Delta M$ needed for the cSW determination.

The axial current:

\[ A_\mu^a(x)={\overline{\psi}}(x)\gamma_\mu\gamma_5\frac{\tau^a}{2}\psi(x) \]

The pseudo scalar density:

\[ P^a(x)={\overline{\psi}}(x)\gamma_5\frac{\tau^a}{2}\psi(x) \]

The boundary pseudo scalar density at t=0

\[ {\cal O}^a=a^6\sum_{\vec{x},\vec{y}}\overline{\zeta}\left(\vec{x}\right) \gamma_5\frac{\tau^a}{2}\zeta\left(\vec{y}\right) \]

The boundary pseudo scalar density at t=T

\[ {\cal O'}^a=a^6\sum_{\vec{x},\vec{y}}\overline{\zeta}'\left(\vec{x}\right) \gamma_5\frac{\tau^a}{2}\zeta'\left(\vec{y}\right) \]

The two point functions are

\[ f_A(x_0)=-\frac{1}{N_f^2-1}\left\langle{A_0^a(x_0){\cal O}^a}\right\rangle =\frac{1}{2}\sum_{\vec{v},\vec{y}}{\rm tr}\left( \left\langle{\zeta(\vec{v}){\overline{\psi}}(x)}\right\rangle\gamma_0\gamma_5 \left\langle{\psi(x)\overline{\zeta}(\vec{y})}\right\rangle\gamma_5\right) \]

\[ f_A'(x_0)=+\frac{1}{N_f^2-1}\left\langle{A_0^a(T-x_0){\cal O'}^a}\right\rangle =-\frac{1}{2}\sum_{\vec{v},\vec{y}}{\rm tr}\left( \left\langle{\zeta'(\vec{v}){\overline{\psi}}(T-x_0)}\right\rangle\gamma_0\gamma_5 \left\langle{\psi(T-x_0)\overline{\zeta}'(\vec{y})}\right\rangle\gamma_5\right) \]

The axial current:

\[ A_\mu^a(x)={\overline{\psi}}(x)\gamma_\mu\gamma_5\frac{\tau^a}{2}\psi(x) \]

The pseudo scalar density:

\[ P^a(x)={\overline{\psi}}(x)\gamma_5\frac{\tau^a}{2}\psi(x) \]

The boundary pseudo scalar density at t=0

\[ {\cal O}^a=a^6\sum_{\vec{x},\vec{y}}\overline{\zeta}\left(\vec{x}\right) \gamma_5\frac{\tau^a}{2}\zeta\left(\vec{y}\right) \]

The boundary pseudo scalar density at t=T

\[ {\cal O'}^a=a^6\sum_{\vec{x},\vec{y}}\overline{\zeta}'\left(\vec{x}\right) \gamma_5\frac{\tau^a}{2}\zeta'\left(\vec{y}\right) \]
