Monte Carlo事件生成器Herwig++（3.0版）的主要新版本现已推出。此版本标志着Herwig++和HER-WIG开发的结束，因此构成了Herwig事件生成器系列第7版的第一个主要版本。新版本对事件模拟进行了许多重大改进，包括：几乎所有标准模型过程的内置NLO硬过程计算，通过两个减法模块与角序和偶极簇射模块匹配，（MC@ NLO型）和乘法角序簇射中的QED辐射和自旋关联;硬过程和部分子簇射中扰动不确定性的一致处理。一些新的特点将在所附出版物中详细介绍，手册的更新将在适当时候进行。
A major new release of the Monte Carlo event generator Herwig++ (version 3.0) is now available. This release marks the end of distinguishing Herwig++ and HER-WIG development and therefore constitutes the first major release of version 7 of the Herwig event generator family. The new version features a number of significant improvements to the event simulation, including: built-in NLO hard process calculation for virtually all Standard Model processes, with matching to both angular-ordered and dipole shower modules via both subtractive (MC@NLO-type) and multiplicative (Powheg-type) algorithms; QED radiation and spin correlations in the angular-ordered shower; a consistent treatment of perturbative uncertainties within the hard process and parton showering. Several of the newfeatures will be covered in detail in accompanying publications, and an update of the manual will follow in due course.
