论文摘要
我们介绍了第一个具有相互作用的大规模和无质量领域的知名综合性田地理论。我们证明了对无质量部门的知识对于理解大规模部门的范围至关重要。该频谱中的多项式中的术语在空间体积中（伯特·安萨兹（Bethe Ansatz）在大规模理论中足够的准确性）不仅需要像吕舍尔（Lüscher）样校正（通常是指数级的），而且还需要完整的TBA积分方程。这些思想对ADS/CFT的含义的动机，但这里仅出现现场理论的结果。
We present the first known integrable relativistic field theories with interacting massive and massless sectors. And we demonstrate that knowledge of the massless sector is essential for understanding of the spectrum of the massive sector. Terms in this spectrum polynomial in the spatial volume (the accuracy for which the Bethe ansatz would suffice in a massive theory) require not just Lüscher-like corrections (usually exponentially small) but the full TBA integral equations. We are motivated by the implications of these ideas for AdS/CFT, but present here only field-theory results.
