Dimension-eight operators in the weak OPE
Weak amplitude attenuation amplitude weak Hamiltonian separation
2014/12/22
We argue that there is a potential flaw in the standard treatment of weak decay amplitudes, including that of ǫ′/ǫ. We show that (contrary to conventional wisdom) dimension-eight operators d...

OPE Heavy-Quark Mass Heavy-Meson Decay Constants
2011/1/7
We present a sum-rule extraction of the decay constants of heavy-light mesons from the two-point correlator of pseudoscalar currents. To this end, we compare the perturbative expansions for the correl...

臭氧生成效率（OPE） 计算方法 观测结果 影响因素
2009/11/10
大气光化学系统的非线性特征增加了O3控制的复杂性，因此各种有助于O3控制对策制定的指标研究备受关注，臭氧生成效率（OPE）就属于这样一种指标。对OPE相关的主要研究成果进行了综述，回顾了OPE定义及计算方法的演变，总结了OPE的空间和季节变化研究结果，分析、讨论了影响OPE的几个主要因素，指出了OPE研究中存在的问题和未来需要加强的方面。我国OPE研究非常缺乏，鉴于我国城市和区域O3污染形势，建议...
