Highly energetic proton/electron beam fixed-target experiments extend an opportunity to probe the sub-GeV dark matter and associated interactions. In this work, we have explored the sensitivity of DUNE (Deep Underground Neutrino Experiment) for sub-GeV leptophobic dark matter, i.e., this dark matter barely couples with the leptons. Baryon number gauge theory can predict the existence of leptophobic cold dark matter particle candidates. In our work, the dark matter candidate is considered to be scalar whose mass is defined by the symmetry breaking of new baryonic gauge group . In this scenario, a light scalar dark matter couples with the standard model candidates via vector boson mediator which belongs to the baryonic gauge group . This leptophobic dark matter dominantly couples to the quarks. Under this scenario, new parameter space for is explored by DUNE for leptophobic dark matter candidates. This new parameter space allowed to get a lower value than the present exiting constraint value of , i.e., .

DUNE排毒性暗物质前景

高能质子/电子束固定目标实验为探索亚GeV暗物质及其相关相互作用提供了机会。在这项工作中，我们探索了DUNE（深层地下中微子实验）对亚GeV疏疏性暗物质的敏感性，即，这种暗物质几乎与轻子不耦合。重子数规理论可以预测存在疏氨酸冷暗物质颗粒候选物。在我们的工作中，暗物质候选者被认为是标量，其质量由新重子规群的对称破坏定义。在这种情况下，轻量级暗物质通过矢量玻色子介体与标准候选模型耦合，而矢量玻色子介体属于重子规组。疏血性暗物质主要与夸克结合。在这种情况下，DUNE会为疏散性暗物质候选者探索新的参数空间。这个新的参数空间允许获得比当前的现有约束值更低的值，即。
