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.

该项目旨在提高部分子簇射的准确性，部分子簇射是模拟高能粒子碰撞所用的一个基本要素。部分子簇射产生碰撞中产生的大量粒子，近似于量子色动力学的辐射模式。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的大的不确定性。该项目将研究提高部分子簇射精度的新方法，并确定大型强子对撞机正在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、高光度计划具有特殊的重要性。
