Abstract:
With the discovery of a Higgs boson at the Large Hadron Collider (LHC) a
new window of exploration of fundamental interactions is now available. The study of the couplings of this Higgs boson to other particles and the search for new bosons have become a focus. Based on features of the data collected by experiments at the LHC during
Run 1 the hypothesis of a new boson was formulated and the compatibility with the data was estimated. In this hypothesis the new boson would have a mass around 270 GeV and would decay in to the Higgs boson and another scalar, referred to as S, among other
decays. This results in a number of predictions that will be summarized. The compatibility of the hypothesis with new data reported by the experiments will also be discussed.
摘要：
随着希格斯玻色子的发现，希格斯玻色子和其他粒子的耦合以及搜寻新粒子成为了焦点。在分析了LHC上各实验组Run I 数据后，我们提出了一个和数据吻合的新玻色子的假设。在这个假设中，这个玻色子有大约270GeV的质量，并且可以衰变到希格斯玻色子和另一个标量粒子（S）。该报告将讨论这个玻色子和其在实验中的观测效应，以及在实验数据中的吻合情况。
