Femtoscopy中的寿命效应

Exploring Lifetime Effects in Femtoscopy

D. A. Brown, R. Soltz, J. Newby, A. Kisiel

摘要:

我们在两个爆轰波模型中研究了共振和发射持续时间尾在RHIC飞秒激光观测中的作用。我们发现非高斯分量与已发布的源成像数据比较良好,但当将现实的接受切割应用于模型时,从高斯拟合获得的R_out值对非高斯贡献并不不敏感。

英文摘要:

We investigate the role of lifetime effects from resonances and emission duration tails in femtoscopy at RHIC in two Blast-Wave models. We find the non-Gaussian components compare well with published source imaged data, but the value of R_out obtained from Gaussian fits is not insensitive to the non-Gaussian contributions when realistic acceptance cuts are applied to models.
