NLO矩阵元和截断簇射

NLO matrix elements and truncated showers

Stefan Hoeche, Frank Krauss, Marek Schonherr, Frank Siegert

摘要:

在本出版物中,提出了一种算法,该算法将ME+PS方法与POWHEG方法相结合,将树级矩阵元素序列合并到包含的事件样本中,该方法将精确的次领先阶矩阵元素结果与部分子簇射相结合。它是与MENLOPS技术并行开发的,并已在事件生成器Sherpa中实现。这种方法的好处是举例说明了一些第一次预测的一些过程,即生产喷注在e+ e-湮灭,在深非弹性ep散射,与单一的W,Z或希格斯玻色子玻色子,并与矢量玻色子对强子对撞机。

英文摘要:

In this publication, an algorithm is presented that combines the ME+PS approach to merge sequences of tree-level matrix elements into inclusive event samples with the POWHEG method, which combines exact next-to-leading order matrix element results with the parton shower. It was developed in parallel to the MENLOPS technique and has been implemented in the event generator Sherpa. The benefits of this approach are exemplified by some first predictions for a number of processes, namely the production of jets in e+ e- annihilation, in deep-inelastic ep scattering, in association with single W, Z or Higgs bosons, and with vector boson pairs at hadron colliders.
