We investigate the structure of the moduli space of 9D heterotic interpolating models with a complete set of Wilson line backgrounds and a radius parameter by computing the one-loop partition functions and the cosmological constants and by deriving the massless spectra, paying attention to the region a0 where supersymmetry is asymptotically restoring. We find some special planes and points in the moduli space where the gauge symmetry is enhanced and/or massless fermions appear. The gauge symmetry is maximally enhanced at the minima of the one-loop effective potential where the cosmological constant is negative.

9D杂散插值模型的稳定性,增强的规范对称性和抑制的宇宙常数

我们通过计算单环分配函数和宇宙常数,并推导无质量谱,关注区域,研究了具有完整的威尔逊线背景和半径参数的9D杂项插值模型的模空间结构 一种0超对称渐近地恢复。我们在模量空间中发现了一些特殊的平面和点,其中规范的对称性得到了增强,并且/或者出现了无质量的费米子。在宇宙常数为负的一环有效电势的最小值处,规范的对称性得到最大增强。
