结果表明，对于任何非零质量，Dirac型中微子都表现出BCS超流性。库珀对是由左手中微子和右手中微子之间的吸引标量希格斯玻色子交换形成的;在标准的SU（2）x U（1）理论中，右手中微子不与任何其他玻色子耦合。计算了中微子质量和化学势为任意值时的差距、临界温度和Pippard相干长度。虽然这种超流体可能存在，但探测它将是一个重大挑战。
It is shown that Dirac-type neutrinos display BCS superfluidity for any nonzero mass. The Cooper pairs are formed by attractive scalar Higgs boson exchange between left- and right-handed neutrinos; in the standard SU(2) x U(1) theory, right-handed neutrinos do not couple to any other boson. The value of the gap, the critical temperature, and the Pippard coherence length are calculated for arbitrary values of the neutrino mass and chemical potential. Although such a superfluid could conceivably exist, detecting it would be a major challenge.
