标题： Signatures of lower scale gauge coupling unification in the Standard Model due to extended Higgs sector

摘要： 规范耦合统一可以在大约5 x 10^{13} GeV的统一尺度上实现，如果标准模型标量部分通过额外的类希格斯双态进行扩展的话。 以手征Z*和W*矢量玻色子形式出现的相关新标量自由度可能在大约700 GeV时“可见”。 它们最终对重夸克的偏好耦合解释了这些玻色子在第一轮LHC运行中未被观测到的现象，并为第二轮LHC运行提供了有希望的预期。 显示英文摘要

摘要： The gauge coupling unification can be achieved at a unification scale around 5 x 10^{13} GeV if the Standard Model scalar sector is extended with extra Higgs-like doublets. The relevant new scalar degrees of freedom in the form of chiral Z* and W* vector bosons might "be visible" already at about 700 GeV. Their eventual preferred coupling to the heavy quarks explains the non observation of these bosons in the first LHC run and provides promising expectation for the second LHC run.
