辐射中微子质量模型中亲轻子暗物质的直接探测

Direct Detection of Leptophilic Dark Matter in a Model with Radiative Neutrino Masses

Daniel Schmidt, Thomas Schwetz, Takashi Toma

摘要:

我们考虑了暗物质(DM)和辐射中微子质量产生的电弱尺度模型。尽管DM具有亲轻子性质,与夸克和胶子没有直接耦合,但与核的散射是通过光子交换在1圈水平上引起的。实际上,存在电荷-电荷、偶极-电荷和偶极-偶极相互作用。我们调查的参数空间一致的约束中微子质量和混合,带电轻子味违反,微扰,和正确的DM丰度的热生产,并计算预期的事件率DM直接检测实验。我们发现,目前的数据从XENON 100开始限制某些区域的允许的参数空间,而未来的数据从XENON 1 T有可能显着探测模型。

英文摘要:

We consider an electro-weak scale model for Dark Matter (DM) and radiative neutrino mass generation. Despite the leptophilic nature of DM with no direct couplings to quarks and gluons, scattering with nuclei is induced at the 1-loop level through photon exchange. Effectively, there are charge-charge, dipole-charge and dipole-dipole interactions. We investigate the parameter space consistent with constraints from neutrino masses and mixing, charged lepton-flavour violation, perturbativity, and the thermal production of the correct DM abundance, and calculate the expected event rate in DM direct detection experiments. We show that current data from XENON100 start to constrain certain regions of the allowed parameter space, whereas future data from XENON1T has the potential to significantly probe the model.
