鉴于最近在大型强子对撞机上观察到的 750 GeV 双光子异常，我们研究了适应基于最近提出的测量双希格斯双峰模型的标准模型预测偏差的可能性。该模型将两个希格斯双峰嵌入到非交换规范组 S U (2) H 的双峰中，而标准模型 S U (2) L 右手费米子单峰与新的重费米子配对形成 S U (2) H 双峰，而 S U (2) L 左手费米子双峰是 S U (2) H 下的单峰。一个 S U (2) H 标量双峰为新的重费米子以及 S U (2) H 规范玻色子提供质量，可以通过胶子聚变产生，并随后衰变成两个光子，新的费米子在三角形环中循环，以解释与标准模型预测的偏差。
In light of the recent 750 GeV diphoton anomaly observed at the LHC, we study the possibility of accommodating the deviation from the standard model prediction based on the recently proposed Gauged Two Higgs Doublet Model. The model embeds two Higgs doublets into a doublet of a non-abelian gauge group S U (2) H, while the standard model S U (2) L right-handed fermion singlets are paired up with new heavy fermions to form S U (2) H doublets, and S U (2) L left-handed fermion doublets are singlets under S U (2) H. An S U (2) H scalar doublet, which provides masses to the new heavy fermions as well as the S U (2) H gauge bosons, can be produced via gluon fusion and subsequently decays into two photons with the new fermions circulating the triangle loops to account for the deviation from the standard model prediction.
