标题： CMS Measurements of the Higgs-like Boson In the Two Photon Decay Channel

摘要： CMS报告了对125 GeV处类希格斯玻色子分析的最新更新的初步结果，包括2011年和2012年完整数据集的结果。 利用5.1$fb^{-1}$的7 TeV数据和19.6$fb^{-1}$的8 TeV数据，观察到信号强度为标准模型（SM）预期的$0.78^{+0.28}_{-0.26}$倍，质量为$125.4\pm0.8$ GeV。 相对于仅背景预测的这一共振的显著性为$3.2\sigma$。 基于截断的交叉验证分析在124.5 GeV处观察到信号强度为 SM 预期的$1.11^{+0.32}_{-0.30}$倍，显著性为$3.9\sigma$。 显示英文摘要

摘要： CMS reports on the recently updated, preliminary results with the full datasets of 2011 and 2012 in the analysis of the Higgs-like Boson at 125 GeV. Utilizing 5.1$fb^{-1}$ of 7 TeV data and 19.6$fb^{-1}$ of 8 TeV data, a signal strength of $0.78^{+0.28}_{-0.26}$ times the Standard Model (SM) expectations with a mass of $125.4\pm0.8$ GeV is observed. The significance of this resonance with respect to the background only prediction is $3.2\sigma$. The cut-based cross-check analysis observes signal strength of $1.11^{+0.32}_{-0.30}$ times the SM expectations with a significance of $3.9\sigma$ at 124.5 GeV.
