论文摘要
搜索希格斯玻色子的异国情调衰变对一对光伪尺度，每种伪库随后腐烂成一对光子。该搜索使用$ \ sqrt {s} $ = 13 tev在LHC处记录的proton-proton碰撞中的数据，该数据对应于132 fb $^{ - 1} $的集成光度。该分析从Higgs玻色子衰变探测为15-62 GEV范围内的质量玻色子，这在最终状态下导致四个溶解的光子。没有观察到与仅背景假设的显着偏差。上限设置在希格斯玻色子生产横截面的乘积上，并分支分支为四个光子。观察到的（预期）极限范围从0.80（1.00）fb的伪玻色子质量为15 GEV到0.26（0.24）Fb的质量为62 GEV，在95％的置信度下为62 GEV。
A search for the exotic decay of the Higgs boson to a pair of light pseudoscalars, each of which subsequently decays into a pair of photons, is presented. The search uses data from proton-proton collisions at $\sqrt{s}$ = 13 TeV recorded with the CMS detector at the LHC that corresponds to an integrated luminosity of 132 fb$^{-1}$. The analysis probes pseudoscalar bosons with masses in the range 15-62 GeV, coming from the Higgs boson decay, which leads to four well-isolated photons in the final state. No significant deviation from the background-only hypothesis is observed. Upper limits are set on the product of the Higgs boson production cross section and branching fraction into four photons. The observed (expected) limits range from 0.80 (1.00) fb for a pseudoscalar boson mass of 15 GeV to 0.26 (0.24) fb for a mass of 62 GeV at 95% confidence level.
