Recent astrophysical and terrestrial experiments have motivated the proposal of a dark sector with GeV-scale gauge boson force carriers and new Higgs bosons. We present a search for a dark Higgs boson using 516 fb(-1) of data collected with the BABAR detector. We do not observe a significant signal and we set 90% confidence level upper limits on the product of the standard model-dark-sector mixing angle and the dark-sector coupling constant.
最近的天体物理和地面实验促使人们提出了一个带有 GeV 规模规范玻色子力载体和新希格斯玻色子的暗物质区域。我们利用 BABAR 探测器采集的 516 fb(-1) 数据进行了暗希格斯玻色子的搜索。我们没有观察到显著的信号,并对标准模型-暗物质区域混合角和暗物质区域耦合常数的乘积设定了 90%置信水平的上限。
