摘要:

格点量子色动力学模拟提供了关于约束弦(通量管)的世界面动力学的重要信息。从晶格光谱中精确提取世界面$S$ -矩阵需要考虑偏振效应。近似可积性的低能量世界片理论使得有可能应用热力学贝特Anterior纳入极化效应在所有订单的绕组的数量和在领先的订单中的衍生物展开。然而,在存在不可积效应和多粒子状态的情况下,这种技术的系统应用变得越来越具有挑战性。我们指出,最近理解的重力敷料和$T\bar{T}$变形之间的等价性提供了一个完全系统的和简单的配方,将在存在的任意非弹性和任何数量的粒子的领先的极化效应。我们用几个例子来说明这种技术。

英文摘要:

Lattice QCD simulations provide crucial information about the worldsheet dynamics of confining strings (flux tubes). An accurate extraction of the worldsheet $S$-matrix from lattice spectra requires accounting for polarization effects. Approximate integrability of the low energy worldsheet theory makes it possible to apply the Thermodynamic Bethe Ansatz to incorporate polarization effects at all orders in the number of windings and at the leading order in the derivative expansion. However, a systematic application of this technique in the presence of non-integrable effects and for multiparticle states becomes increasingly challenging. We point out that a recently understood equivalence between gravitational dressing and $T\bar{T}$ deformation provides a fully systematic and straightforward recipe to incorporate the leading polarization effects in the presence of an arbitrary inelasticity and for any number of particles. We illustrate this technique with several examples.
