论文摘要
提出了一种用于模拟geant4中电子和muons的深色bremsstrahlung的技术。总横截面是使用weizsäcker-williams近似来计算的,并通过在madgraph/makedvent中产生的缩放事件来产生传出的运动学,从而使较低入射的Lepton Energies产生,从而使模拟能够考虑较厚的目标和Lepton源。与在任意粒子能量下产生的专用样品相比,典型的精度优于5%。
A technique for the simulation of dark bremsstrahlung for electrons and muons in GEANT4 is presented. The total cross section is calculated using the Weizsäcker-Williams approximation and the outgoing kinematics are produced by scaling events produced in MadGraph/MadEvent to lower incident lepton energies, allowing the simulation to account for thick targets and lepton sources without fixed energies. Compared with dedicated samples produced at an arbitrary particle energy, typical precision of better than 5% is achieved.
