Glauber-Lachs formula-based analysis of three-pion Bose-Einstein correlation data in $pp$ collisions at 7 TeV from the LHCb Collaboration

Abstract

In this study, we combine the Glauber--Lachs formula from quantum optics and the two-component picture for pion production to analyze data on two- and three-pion Bose--Einstein correlation in $pp$ collisions at 7 TeV from the LHCb Collaboration. For the pion exchange function $E_{2B}$, we chose a dipole form and an inverse one-and-a-half pole form. The extensions are computed in the configuration space of four-dimensional Euclidean space ($\xi =\sqrt{|r_1-r_2{|}^2+(t_1-t_2{)}^2}$).
