(0,2)杂化CFT/几何联系中带电无质量态的计数

Counting charged massless states in the (0,2) heterotic CFT/geometry connection

Matteo Beccaria, Maximilian Kreuzer, Andrea Puhm

摘要:

我们使用简单的电流技术和它们与离散挠率轨道的关系来研究具有非有理内部N=2 SCFT的(0,2)CFT/几何对偶。利用推广的Poincaré多项式和可由椭圆亏格计算的补Poincaré多项式,计算了杂化SO(10)GUT模型荷电谱的显式表达式.虽然非BPS状态对带电光谱有贡献,但它们的贡献也可以在非理性情况下确定。为了建立模型,推广到SU(5)和SM规范群,可以利用朗道-金兹伯格轨道的例子。

英文摘要:

We use simple current techniques and their relation to orbifolds with discrete torsion for studying the (0,2) CFT/geometry duality with non-rational internal N=2 SCFTs. Explicit formulas for the charged spectra of heterotic SO(10) GUT models are computed in terms of their extended Poincaré polynomials and the complementary Poincaré polynomial which can be computed in terms of the elliptic genera. While non-BPS states contribute to the charged spectrum, their contributions can be determined also for non-rational cases. For model building, with generalizations to SU(5) and SM gauge groups, one can take advantage of the large class of Landau-Ginzburg orbifold examples.
