论文摘要
我们介绍了搜索Argoneut实验在Fermilab执行的重QCD轴的结果。我们搜索在Numi Neutrino束靶标中产生的重轴，并吸收腐烂到Dimuon对，可以使用Argoneut和Minos在检测器附近的独特功能来识别。该衰减通道是由一类庞大的QCD轴轴模型激励的，该模型解决了强大的CP和轴突质量问题，其轴质质量高于Dimuon阈值。对于以前未开发的质量范围为0.2-0.9 GEV的重轴，我们在95 \％的置信度下获得了新的约束，对于数十TEV附近的轴衰变常数。
We present the results of a search for heavy QCD axions performed by the ArgoNeuT experiment at Fermilab. We search for heavy axions produced in the NuMI neutrino beam target and absorber decaying into dimuon pairs, which can be identified using the unique capabilities of ArgoNeuT and the MINOS near detector. This decay channel is motivated by a broad class of heavy QCD axion models that address the strong CP and axion quality problems with axion masses above the dimuon threshold. We obtain new constraints at a 95\% confidence level for heavy axions in the previously unexplored mass range between 0.2-0.9 GeV, for axion decay constants around tens of TeV.
