Baxter方程在N=4 SYM中的强耦合展开

Strong coupling expansion of Baxter equation in N=4 SYM

A. V. Belitsky

摘要:

在极大超对称规范理论中,单迹具有协变导数的局域Wilson算子的反常维数被认为是由变形的非紧sl(2)Baxter方程产生的.为了克服该方程渐近性质的局限性,我们在大共形自旋的单对数极限下对该方程进行了强耦合的系统展开。分析减少到Riemann-Hilbert问题相应的预解的Bethe根在每一个顺序的准经典的扩展。我们明确地构建了强耦合下最低两阶的预解式,并找到了底层长程自旋链的所有局部守恒电荷。

英文摘要:

The anomalous dimensions of single-trace local Wilson operators with covariant derivatives in maximally supersymmetric gauge theory are believed to be generated from a deformed noncompact sl(2) Baxter equation. We perform a systematic expansion of this equation at strong coupling in the single-logarithmic limit of large conformal spin to overcome the limitation of the asymptotic nature of the equation. The analysis is reduced to Riemann-Hilbert problems for corresponding resolvents of Bethe roots in each order of the quasiclassical expansion. We explicitly construct the resolvents in the lowest two orders in strong coupling and find all local conserved charges of the underlying long-range spin chain.
