论文摘要
这项工作的主要任务是找到一种快速，可靠的方法来确定SPD实验中的PP-Collision Time T0。使用物理动机，从重建粒子轨道的输入通量中，我们确定了一个子集的一部分，该子集用于计算事件碰撞时间的无偏估计。估计的不确定性约为30 ps。该方法快速（每个事件少于300 ns）且可靠，因此它将允许在SPD实验中处理输入事件的高通量。
The main task of this work is to find a fast and robust way to determine pp-collision time t0 at the SPD experiment. Using physics motivations, from the input flux of reconstructed particles' tracks we identify a subset of pions which is used to calculate the unbiased estimation of the event collision time. The uncertainty of the estimation is about 30 ps. This method is fast (less than 300 ns per event) and reliable, thus it will allow to process the high flux of input events at the SPD experiment.
