✦ Synopsis
We present preliminary evidence of BCS diquark condensation in the 3 + 1 dimensional NambuJona-Lasinio (NJL) model at non-zero chemical potential (cl) on the lattice. Large N results are used to match the model's parameters to low energy, zero density phenomenology.
A diquark source j is added in a partially quenched approximation to enable the measurement of lattice diquark observables. In particular measurements are made of the diquark condensate and susceptibilities as functions of j which support the existence of a BCS phase at high /I.
