TFourQuark : Creates the four quark vertex required for the NPR of four-quark ops
|
||||||
|
|
||||||
|
V_{Gamma_1,Gamma_2} = sum_x [ ( g5 * adj(S'(x,p2)) * g5 * G1 * S'(x,p1) )_ci,cj;si,sj x ( g5 * adj(S'(x,p2)) * g5 * G2 S'(x,p1) )_ck,cl;sk,cl ]
|
||||||
|
|
||||||
|
Create a bilinear vertex for G1 and G2 the spin and colour indices are kept free. Where there are 16 potential Gs.
|
||||||
|
We then find the outer product of V1 and V2, keeping the spin and colour indices uncontracted
|
||||||
|
Then this is summed over the lattice coordinate
|
||||||
|
Result is a SpinColourSpinColourMatrix - with 4 colour and 4 spin indices.
|
||||||
|
We have up to 256 of these including the offdiag (G1 != G2).
