论文摘要
我们估计了沙丘实验对与中微子相互作用的新物理颗粒的敏感性，考虑到偶极子门户对重中性瘦素的偶极子门户和具有Lepton-number $ 2 $的中性粒细胞标量为示例。我们证明，从沙丘通量的高能尾部中微子，具有能量$e_ν\ gtrsim 5-10 \ text {gev} $，可能会显着提高对这些模型的敏感性，从而可以搜索像$ \ simeq 10 \ text {gev} $的颗粒。我们还研究了所谓的tau优化中微子束构型的影响，该束略微提高了对此处考虑的新物理模型的敏感性。对于这两种模型，我们都考虑了新的生产渠道（例如深弹性散射），并详细比较了检测器中不同特征。
We estimate the sensitivity of the DUNE experiment to new physics particles interacting with neutrinos, considering the dipole portal to heavy neutral leptons and a neutrinophilic scalar with lepton-number $2$ as examples. We demonstrate that neutrinos from the high-energy tail of the DUNE flux, with energies $E_ν\gtrsim 5-10\text{ GeV}$, may significantly improve the sensitivity to these models, allowing to search for particles as heavy as $\simeq 10\text{ GeV}$. We also study the impact of the so-called tau-optimized neutrino beam configuration, which slightly improves sensitivity to the new physics models considered here. For both models, we consider new production channels (such as deep-inelastic scattering) and provide a detailed comparison of different signatures in the detector.
