$\extbf{HoTCoffeeh}$($\extbf{H}$anbury BR$\extbf{o}$Wn-$\extbf{T}$Wiss$\textbf{Co}$r函数与半径的关系$\textbf{f}$rom$\extbf{e}$ventbf{e}$ventBF{h}$ydrodym)是一种新的计算工具，它可以确定包括共振衰变贡献在内的逐个事件(EBE)流体动力学的汉伯里-布朗-特维斯(HBT)带电介子($\pi^+$)关联函数和半径。在这篇文章中，我们回顾了计算HBT关联函数和包含共振衰变贡献的半径的基本公式，并讨论了我们以HoTCoffeeh的形式实现这种公式的方法。该工具可以很容易地与其他数值程序包结合起来，以模拟重离子碰撞的演化，从而提取对重离子可观测值的预测。
$\textbf{HoTCoffeeh}$ ($\textbf{H}$anbury Br$\textbf{o}$wn-$\textbf{T}$wiss $\textbf{Co}$rrelation $\textbf{f}$unctions and radii $\textbf{f}$rom $\textbf{e}$vent-by-$\textbf{e}$vent $\textbf{h}$ydrodynamics) is a new computational tool which determines Hanbury Brown-Twiss (HBT) charged pion ($\pi^+$) correlation functions and radii for event-by-event (EBE) hydrodynamics with fluctuating initial conditions in terms of Cooper-Frye integrals, including resonance decay contributions. In this paper, we review the basic formalism for computing the HBT correlation functions and radii with resonance decay contributions included, and discuss our implementation of this formalism in the form of HoTCoffeeh. This tool may be easily integrated with other numerical packages for the purpose of simulating the evolution of heavy-ion collisions and thereby extracting predictions for heavy-ion observables.
