论文摘要
识别重建的Hadronic喷气机的味道对于精确现象学和对撞机实验的新物理学的搜索至关重要，因为它允许查明特定的散射过程并拒绝背景。 LHC处的喷气测量值几乎是使用抗$ k_t $算法普遍执行的，但是，没有任何方法可以定义此算法的喷气味，该算法是红外和孔（IRC）安全的方法。我们提出了一种新方法，一种风味敷料算法，对扰动理论中的所有订单都安全，并且可以与任何喷气机的任何定义结合使用。我们在$ \ mathrm {e}^+\ mathrm {e}^ - $和$ \ mathrm {p} \ mathrm {p} $ emoverments中测试该算法\ Mathrm {Z}+\ Mathrm {B} \ text {-jet} $ process作为一个实用应用程序。
Identifying the flavour of reconstructed hadronic jets is critical for precision phenomenology and the search for new physics at collider experiments, as it allows to pinpoint specific scattering processes and reject backgrounds. Jet measurements at the LHC are almost universally performed using the anti-$k_T$ algorithm, however no approach exists to define the jet flavour for this algorithm that is infrared and collinear (IRC) safe. We propose a new approach, a flavour dressing algorithm, that is IRC safe to all orders in perturbation theory and can be combined with any definition of a jet. We test the algorithm in $\mathrm{e}^+\mathrm{e}^-$ and $\mathrm{p}\mathrm{p}$ environments, and consider the $\mathrm{p}\mathrm{p} \to \mathrm{Z}+\mathrm{b}\text{-jet}$ process as a practical application.
