AI 中文摘要
我们从代数根系几何推导出精确的无质量S矩阵,并推导出热力学Bethe ansatz(TBA)方程,这些方程生成最小重整化群(RG)流。我们展示了P. Dorey的几何构造(最初为有质量S矩阵开发)如何扩展到无质量情形,并证明这些新的$S$-矩阵直接满足自举方程。我们关注最小D_n陪集共形场论(CFT),它们是具有紧致化半径\sqrt{n/2}的c=1自由玻色子CFT,并通过分析TBA找到它们的紫外完备化。
英文摘要
We derive exact massless S-matrices from algebraic root-system geometry and derive thermodynamic Bethe ansatz (TBA) equations that generate minimal renormalization group (RG) flows. We show how P. Dorey's geometric construction, originally developed for massive S-matrices, can be extended to massless cases and prove that these new $S$-matrices straightforwardly satisfy the bootstrap equations. We focus on minimal D_n coset CFTs, which are c=1 free-boson CFTs with compactification radius \sqrt{n/2}, and find their UV completions by analyzing the TBA.
