Principles and prospects of Bose-Einstein correlation study at BESIII*

Abstract

One method to determine the characteristic parameters of a hadron production source is to measure Bose-Einstein correlation functions. In this paper, we present fundamental concepts and formulas related to Bose-Einstein correlations, focusing on the measurement principles and the Lund model from an experimental perspective. We perform Monte Carlo simulations using the Lund model generator in the 2–3 GeV energy range. Through these feasibility studies, we identify key features of Bose-Einstein correlations that offer valuable insights for experimental measurements. Utilizing data samples collected at BESIII, we propose measurements of Bose-Einstein correlation functions, with the expected experimental precision of the hadron source radius and incoherence parameter at the level of a few percent.
