The Bose-Einstein Correlations and the Strong Coupling Constant at Low Energies

Abstract

It is shown that α s ( E ) , the strong coupling constant, can be determined in the non-perturbative regime from Bose-Einstein correlations (BEC). The obtained α s ( E ) , where E is the energy of the hadron in the center of mass reference frame of the di-hadron pair, is in agreement with the prescriptions dealt with in the Analytic Perturbative Theory approach. It also extrapolates smoothly to the standard perturbative α s ( E ) at higher energies. Our results indicate that BEC dimension can be considered as an alternative approach to the short-range correlations between hadrons.
