“…( 1). In addition, the ascription of the factor 1 + cos(x 1 − x 2 )(p 1 − p 2 ) to the weight of the pion pair in (1) is not correct for very closely located points x 1 and x 2 because there is no Bose-Einstein enhancement if the two identical bosons are emitted from the same point [12,30]. The effect is small for large systems with large number of independent emitters.…”

A method for quantum corrections of Hanbury-Brown/Twiss (HBT) interferometric radii produced by semi-classical event generators is proposed. These corrections account for the basic indistinguishability and mutual coherence of closely located emitters caused by the uncertainty principle. A detailed analysis is presented for pion interferometry in p + p collisions at LHC energy ( √ s = 7 TeV). A prediction is also presented of pion interferometric radii for p+Pb collisions at √ s = 5.02 TeV. The hydrodynamic/hydrokinetic model with UrQMD cascade as 'afterburner' is utilized for this aim. It is found that quantum corrections to the interferometry radii improve significantly the event generator results which typically overestimate the experimental radii of small systems. A successful description of the interferometry structure of p + p collisions within the corrected hydrodynamic model requires the study of the problem of thermalization mechanism, still a fundamental issue for ultrarelativistic A + A collisions, also for high multiplicity p + p and p+Pb events.

“…In opposite case when (x i − x j ) 2 ≪ 1/∆p 2 the states are indistinguishable and overlapping integral (2.15) G i j ≈ 1 at t 1 ≈ t 2 since at x i = x j it is just normalization. Then we come back to the fully coherent emission (2.9) which takes place for very closed emitters [9]. So, in both limited cases of chaotic and fully coherent emission Eq.…”
