Member Function Documentation

void Chroma::InlineBuildingBlocks::func	(	const unsigned long	update_no,
		XMLWriter &	xml_out
	)			[protected]

Do the measurement.

Test a meson sequential source.

For the case of a meson, we have evaluated as the sequential source

H(y, 0; tx, p) = exp{ip.x} U(y,x) ^ D(x,0)

H^(y, 0; tx, p) = exp{-ip.x} D(0,x) U(x,y)

Thus we can see that

Tr[ H^(0,0; tx, p) ] = exp{-ip.x} Tr[ D(0,x) U(x,0) ]

which is the desired meson correlator at momentum p and timslice tx
