Title: 校准音调：一种量热器能量校准的新方法

Abstract: The energy calibration of calorimeters at collider experiments, such as the ones at the CERN Large Hadron Collider, is crucial for achieving the experiments physics objectives. Standard calibration approaches have limitations that become more pronounced as detector granularity increases. In this paper we propose a novel calibration procedure to simultaneously calibrate individual detector cells belonging to a particle shower by targeting a well-controlled energy reference. The method bypasses some of the difficulties that exist in more standard approaches, and it is implemented using differentiable programming. Simulated energy deposits in the electromagnetic section of a high-granularity calorimeter are used to study the method and demonstrate its performance. It is shown that the method is able to correct for biases in the energy response. Show Chinese abstract

Abstract: 量能器在对撞机实验中的能量标定，如欧洲核子研究中心大型强子对撞机上的量能器，对于实现实验的物理目标至关重要。 标准的标定方法存在局限性，这些局限性在探测器的颗粒度增加时变得更加明显。 本文提出了一种新的标定程序，通过针对一个受控的能量参考点，同时标定属于粒子簇射的各个探测器单元。 该方法绕过了某些在更标准的方法中存在的困难，并使用可微编程实现。 利用高颗粒度量能器的电磁部分中的模拟能量沉积来研究该方法并展示其性能。 结果表明，该方法能够校正能量响应中的偏差。
