We argue that the two-particle momentum correlation functions ofhigh-multiplicity $p+p$ collisions at the LHC provide a signal for a groundstate structure of a quasi equilibrium state of the longitudinallyboost-invariant expanding quantum field which lies in the future light cone ofa collision. The physical picture is that pions are produced by the expandingquantum emitter with two different scales approximately attributed to theexpanding ideal gas in local equilibrium state and ground-state condensate.Specifically, we show that the effect of suppressing the two-particleBose-Einstein momentum correlation functions increases with increasingtransverse momentum of a like-sign pion pair due to differentmomentum-dependence of the corresponding particle emission regions.
