简要回顾了普适额外维的最小模型。我们解释了如何通过胶子融合和衰变成光子的希格斯生产的横截面被修改，相对于标准模型（SM）的值，由KK粒子运行在循环中，导致增强的gg！h！还有GG！h！W + W横截面。ATLAS和CMS搜索SM希格斯粒子在这些渠道中重新解释的背景下，MUED和用于放置新的限制的MUED参数空间。在95%的置信水平下，只有1到3 GeV之间的小区域（500 GeV < R 1 < 1600 GeV）在mh = 125 GeV附近保持开放。
The minimal model of Universal Extra Dimensions (MUED) is briefly reviewed. We explain how the cross-sections for Higgs production via gluon fusion and decay into photons are modified, relative the the Standard Model (SM) values, by KK particles running in loops, leading to an enhancement of the gg! h! and gg ! h ! W + W cross-sections. ATLAS and CMS searches for the SM Higgs in these channels are reinterpreted in the context of MUED and used to place new limits on the MUED parameter space. Only a small region of between 1 and 3 GeV around mh = 125 GeV for 500 GeV < R 1 < 1600 GeV remains open at the 95 % confidence level.
