论文摘要
我们表明，当通过某些类别的弦乐压实（例如具有相互作用的D-Branes的IIA型方向模型）中的瞬时相互作用而非扰动地产生无菌的主要中微子质量时，则可以在中心群体中的eigenvalue spectrum seetrond suistrime Optier（在中心范围内）的特征性频谱（均可在中心范围内）（均可在中心范围内）（均可在中心范围内（Electrice）范围（均可范围内的eRead fargrach introf）（eytrof）（eytrof）范围内的eRETORD范围（标准型号，即$ m_p \ sim $ pev。这种机制不需要调整各种弦尺，从而激发了一类新型的弦乐中微子选项，涵盖了光中微子质量，EW和深层紫外线尺度。
We show that when sterile Majorana neutrino masses are generated non-perturbatively through instantonic interactions in certain classes of string compactifications (e.g. Type IIA orientifold models with intersecting D-branes), then the eigenvalue spectrum for the tree-level mass term $M_p$ can be within the preferred range of the Neutrino Option resolution to the electroweak (EW) hierarchy and neutrino mass problems of the Standard Model, i.e. $M_p \sim$ PeV. This mechanism holds without tuning for a broad range of string scales, thereby motivating a novel class of string-completed Neutrino Options spanning the light neutrino mass, EW, and deep ultraviolet scales.
