Herwig++ 2.3 Release Note
摘要：
蒙特卡洛程序Herwig++（2.3版）的新版本现已推出。这个版本包括一些改进，包括：将程序扩展到轻子-强子碰撞;在正重最硬发射发生器（POWHEG）方案中包括几个精确到次领先级的过程;在超越标准模型（BSM）物理过程中包括三体衰变和有限宽度效应;基于硬散射过程的色结构重建部分子簇射运动学的新方法，包括激发重子多重态的重子衰变的新模型;在下伏事件的多次散射模型中增加了一个软分量;深度非弹性散射（DIS）和e+e-过程的新矩阵元。
英文摘要：
A new release of the Monte Carlo program Herwig++ (version 2.3) is now available. This version includes a number of improvements including: the extension of the program to lepton-hadron collisions; the inclusion of several processes accurate at next-to-leading order in the POsitive Weight Hardest Emission Generator (POWHEG) scheme; the inclusion of three-body decays and finite-width effects in Beyond the Standard Model (BSM) physics processes; a new procedure for reconstructing the kinematics of the parton shower based on the colour structure of the hard scattering process; a new model for baryon decays including excited baryon multiplets; the addition of a soft component to the multiple scattering model of the underlying event; new matrix elements for Deep Inelastic Scattering (DIS) and e+e- processes.
