Bose-Einstein correlations inK + p and π+ p at 250 GeV/c

Two-pion correlations and multiplicity effects in La on La collisions

“…In Refs. [27,30,33] no such multiplicity dependence has been found, whereas Refs. [20-23, 25, 31] report an increase of the radius with increasing multiplicity (centrality) of a collision.…”

“…Since the discovery by Goldhaber et al [l, 2] that proton-antiproton annihilations produce more like-charged than oppositely charged pion pairs with small momentum difference; many theoretical [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] and experimental [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] studies have been done to investigate the "Goldhaber-Goldhaber-Lee-Pais" (GGLP) effect. The intensity correlation of two like particles is a consequence of the quantum mechanical symmetry requirement imposed on the wave functions of bosons.…”
