Bridging the accuracy gap: High-precision parton showers for colliders

该项目旨在提高部分子阵雨的准确性，这是模拟高能粒子碰撞的重要组成部分。在一种近似于量子色动力学的辐射模式中，在碰撞中产生大量的粒子。这种近似的低精度转化为在粒子对撞机上进行的关键测量中的大不确定性。该项目将研究提高部分子阵雨精度的新方法，并确定在大型强子对撞机调查的所有过程中相关不确定性的准确估计。这对于后者的高精度、高亮度计划将具有特殊的重要性。

This project aims at improving the accuracy of parton showers, which are an essential ingredient used in the simulation of high-energy particle collisions. Parton showers generate the large set of particles produced in a collision, in an approximation of the radiation pattern of Quantum Chromodynamics. The low precision of this approximation translates into large uncertainties in critical measurements performed at particle colliders. This project will study novel ways of enhancing the precision of parton showers, and determine accurate estimates of associated uncertainties across all processes under investigation at the Large Hadron Collider. It will be of exceptional importance for the latter's high-precision, high-luminosity program.
