BCS diquark condensation in the 3 + id lattice NJL model

We present preliminary evidence of BCS diquark condensation in the 3 + 1 dimensional Nambu-Jona-Lasinio (NJL) model at non-zero chemical potential (μ) on the lattice. LargeN results are used to match the model's parameters to low energy, zero density phenomenology. A diquark sourcej 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 ofj which support the existence of a BCS phase at high μ.
