论文摘要
在未来E $^+$ e $^ - $ colliders的物理事件的重建中，量热计设计在整体检测器性能中起着至关重要的作用。在最终状态下，重建了许多喷气机的事件对喷气能量和角度分辨率的严格要求。需要大约45 GEV的喷气机的能量分辨率必须达到4-5 \％水平，以使W和Z玻色子不变质量有效地分离。我们在本文中证明了如何通过利用针对由分段的晶体和纤维制成的混合双读量热量计量身定制的粒子流量算法来实现这种性能。对于光子和中性辐射的这种量热计的出色能量分辨率和线性（分别为$ 3 \％/\ sqrt {e} $和$ 26 \％/\ sqrt {e} $），固有的均质晶体和二线技术选择的固有方法，可用于识别新方法和新方法，以识别新的界面方法和新方法。虽然本文中介绍的双读粒子流量算法（DR-PFA）处于开发的早期阶段，但它已经证明了混合型双读量热量量量强的潜力，可以通过改善量热计的量化能量重建，而相对于仅6.0 \％\％\％\％for 4.5 for 4.5 for 4.5 for 45 f for 4.5 gev for 4.5 gev。
In the reconstruction of physics events at future e$^+$e$^-$ colliders the calorimeter design has a crucial role in the overall detector performance. The reconstruction of events with many jets in their final state sets stringent requirements on the jet energy and angular resolutions. The energy resolution for jets with energy of about 45 GeV is required to be at the 4-5\% level to enable an efficient separation of the W and Z boson invariant masses. We demonstrate in this paper how such a performance can be achieved by exploiting a particle flow algorithm tailored for a hybrid dual-readout calorimeter made of segmented crystals and fibers. The excellent energy resolution and linearity of such calorimeter for both photons and neutral hadrons ($3\%/\sqrt{E}$ and $26\%/\sqrt{E}$, respectively), inherent to the homogeneous crystals and dual-readout technological choices, provides a powerful handle for the development of a new approach for particle identification and jet reconstruction. While the dual-readout particle flow algorithm (DR-PFA) presented in this paper is at its early stage of development, it already demonstrates the potential of a hybrid dual-readout calorimeter for jet reconstruction by improving the jet energy resolution with respect to a calorimeter-only reconstruction from 6.0\% to about 4.5\% for 45 GeV jets.
