WHIZARD：在LHC和ILC上模拟多粒子过程
WHIZARD: Simulating Multi-Particle Processes at LHC and ILC
摘要：
我们描述了通用的Monte-Carlo事件发生器WHIZARD。该程序自动计算完整的树级矩阵元素，将它们集成到相空间中，评估可观测量的分布，并生成可直接用于检测器模拟的未加权事件样本。过程的复杂性没有主要的限制;使用当前的硬件，该程序已成功地应用于硬散射过程中，最多有8个粒子处于最终状态。矩阵元素被计算为螺旋度振幅，因此自旋和颜色相关性被保留。标准模型，MSSM，和许多替代模型，如小希格斯，异常耦合，或额外的维度或非交换SM扩展的影响已经实现。使用标准接口PDF，beamstrahlung，部分子淋浴和强子化程序，WHIZARD生成完整的物理事件，并涵盖强子，轻子和光子对撞机的物理学。
英文摘要：
We describe the universal Monte-Carlo event generator WHIZARD. The program automatically computes complete tree-level matrix elements, integrates them over phase space, evaluates distributions of observables, and generates unweighted event samples that can be used directly in detector simulation. There is no principal limit on the process complexity; using current hardware, the program has successfully been applied to hard scattering processes with up to eight particles in the final state. Matrix elements are computed as helicity amplitudes, so spin and color correlations are retained. The Standard Model, the MSSM, and many alternative models such as Little Higgs, anomalous couplings, or effects of extra dimensions or noncommutative SM extensions have been implemented. Using standard interfaces to PDF, beamstrahlung, parton shower and hadronization programs, WHIZARD generates complete physical events and covers physics at hadron, lepton, and photon colliders.
