◆ compute() [1/2]

void Chroma::vector_meson::compute	(	LatticeStaggeredPropagator &	quark_props,
		int	j_decay
	)

Compute the local std::vector meson correlators using a single local quark propagator.

I have checked this routine against the MILC code.

StaggeredVectorMesons

This routine computes the three local std::vector mesons.

Caveats: i) It assumes that the propagators you give have been computed in some spatially fixed gauge eg the Coulomb Gauge.

ii) This means that there is only 8 propagators corresponding to the 8 corners of the spatial cube. The props come in an array whose single index std::maps lexicographically to the corners of the cube. ie: prop_index = 0, hypercube_coord (0,0,0,0) prop_index = 1, hypercube_coord (1,0,0,0) prop_index = 2, hypercube_coord (0,1,0,0)

essentially prop_index = x + 2*y + 4*z

    iii) The assumption is that you are working in 4d

Parameters:

 quark_props      -- The array of input propagators (Read)

 j_decay          -- The time direction (has to be Nd-1 for now)
                     (Read)

Implements Chroma::staggered_hadron_corr.
