MonteCarlo BPS-代数与Moonshine的超弦起源

Monstrous BPS-Algebras and the Superstring Origin of Moonshine

Natalie M. Paquette, Daniel Persson, Roberto Volpato

摘要:

我们提供了一个物理推导蒙地卡罗月光。我们表明,麦凯-汤普森系列$T_g$,$g\in \mathbb{M}$,可以被解释为超对称指数计数时空BPS状态在某些杂合弦模型。这些系列的不变性组自然产生的时空T-对偶群和他们的属零属性下降,从这些杂种模型的行为在适当的解压缩限制。我们还表明,空间的BPS-状态形成一个模块的Monstellar李代数$\mathfrak{m}_g$,由Borcherds和Carnahan构造。我们认为,$\mathfrak{m}_g$作为自发破缺的规范对称性代数出现在杂化模型中,其生成元与BPS态精确对应。这给出了$\mathfrak{m}_g$作为一种BPS-代数的解释。

英文摘要:

We provide a physics derivation of Monstrous moonshine. We show that the McKay-Thompson series $T_g$, $g\in \mathbb{M}$, can be interpreted as supersymmetric indices counting spacetime BPS-states in certain heterotic string models. The invariance groups of these series arise naturally as spacetime T-duality groups and their genus zero property descends from the behaviour of these heterotic models in suitable decompactification limits. We also show that the space of BPS-states forms a module for the Monstrous Lie algebras $\mathfrak{m}_g$, constructed by Borcherds and Carnahan. We argue that $\mathfrak{m}_g$ arise in the heterotic models as algebras of spontaneously broken gauge symmetries, whose generators are in exact correspondence with BPS-states. This gives $\mathfrak{m}_g$ an interpretation as a kind of BPS-algebra.
