非标准仿费米子与弦紧化

Nonstandard Parafermions and String Compactification

Andrei Babichenko, Doron Gepner

摘要:

构造了非标准的仿费米子,计算了它们的中心荷和尺寸。然后,我们通过用自由玻色子张量仿费米子来构造新的N=2超共形场论。我们研究了这些理论的谱和模变换。通过张量新的超共形场论和一些极小模型,得到了四维超弦和杂化弦。研究了世代和反世代。我们给出了一个例子的$1^2(5,7)$理论,它被证明有三个净代。

英文摘要:

Nonstandard parafermions are built and their central charges and dimensions are calculated. We then construct new N=2 superconformal field theories by tensoring the parafermions with a free boson. We study the spectrum and modular transformations of these theories. Superstring and heterotic strings in four dimensions are then obtained by tensoring the new superconformal field theories along with some minimal models. The generations and antigenerations are studied. We give an example of the $1^2(5,7)$ theory which is shown to have three net generations.
