论文摘要
我们对Xenon1T在电子后坐力能量光谱中观察到的过量频谱拟合分析，具有中微子磁矩，电荷半径，中微子Millicharge以及新的光矢量和标量介质。在其他实验室实验允许的限制之内，我们发现可以在磁性时刻$ \（2-4）\ times 10^{ - 11}^{ - 11}μ__{b} $的范围内解释，磁矩为$ \（2-6）\（2-6）\ times 10^{ - 31} $ cm $ $ $ $^{2} $ for the Charge Radius，$ \ $ \ $ \ \ $ \ $ \（1.7-3） MILLICHARGE和$（10-100）\ $ kev群众群体的耦合$ 3.5 \ times 10^{ - 7} $用于矢量/轴 - 矢量，$ 1 \ times 10^{ - 6} $，$ 4 \ $ 4 \ times 10^{ - 6} $ scalar和pseudo-scalar Mediators callor call and Times times 10^{ - 6} $。在所有中微子millicharge中，磁矩和矢量介体更适合观察到的光谱。我们还对此处考虑的所有新物理参数产生了限制。
We perform a constrained spectral fit analysis of the excess observed in the electron recoil energy spectrum by XENON1T with neutrino magnetic moment, charge radius, neutrino millicharge and new light vector and scalar mediators. Within the limits allowed by other laboratory experiments we find that the excess can be explained in the range$\ (2-4)\times 10^{-11}μ_{B} $ for the magnetic moment,$\ (2-6)\times 10^{-31}$cm$^{2}$ for the charge radius, $\ (1.7-2.3)\times 10^{-12}e$ for the millicharge and $(10-100)\ $keV masses of light mediators with couplings of $ 3.5\times 10^{-7}$ for vector/axial-vector, $1\times 10^{-6}$ and $4\times 10^{-6}$ for scalar and pseudo-scalar mediators respectively. Among all neutrino millicharge, magnetic moment and vector mediators fit better to the observed spectrum. We also derive constraints on all new physics parameters considered here.
