Possibility of a superfluid in high multiplicity p-p and p-Pb collisions
  We consider the case where the saturated and unequilibriated initial stage of a high multiplicity p-p and p-Pb collision, may, due to high occupation number, display superfluid properties. The special case of an unequilibrated plasma of SU(2) gluons formed in the collision of two nuclei with deeply saturated gluon wave functions is considered. Color gauge symmetry is broken by the presence of a net non-vanishing, space-time dependent color expectation value. A two component scenario is envisioned, containing momentum states that are densely occupied below the saturation scale and a dilute normal fluid of excitations within this state. The spectrum of these excitations is shown to have an energy gap and thus it is hard to excite quanta out of the condensed state. Consequences for the stress energy tensor are outlined, in particular the possibility of a near invisid flow is discussed.
