标题： Distortion of the HBT image by mean field interaction

摘要： 我们研究了平均场相互作用对通过利用哈伯德·布朗和特维斯（HBT）干涉测量技术在超高能重离子碰撞中测量的强子源时空几何的影响。 我们展示了在冻结过程中的π介子振幅的修改如何通过半经典方法被纳入干涉测量的相关函数中。 展示了扭曲图像的剖面。 为了对这些影响进行定量估计，我们基于π介子-π介子散射振幅构建了一个平均场相互作用模型，然后研究了平均场相互作用的影响在多大程度上能够有效地改变HBT半径。 显示英文摘要

摘要： We study effects of a mean-field interaction on the spacetime geometry of the hadron source measured by utilizing the Hanbury Brown and Twiss (HBT) interferometry in the ultrarelativistic heavy-ion collisions. We show how a modification of a pion amplitude, caused in the freeze-out process, is incorporated into the correlation function of the interferometry within a semiclassical method. Profiles of the distorted images are illustrated. To make a quantitative estimate of the effects, we construct a mean-field-interaction model on the basis of the pion-pion scattering amplitude, and then investigate to what extent the effects of the mean-field interaction acts to efficiently modify the HBT radii.
