Uwe Trittmann

AI总结:

应用eLCQ方法在所有部分子区构造渐近本征函数集,通过基函数方法求解二维伴随QCD的谱,重现超对称点质量简并等结果,为验证其他框架提供独立手段。

摘要:

我们将一种方法(“eLCQ”)应用于从对称性寻找哈密顿量的渐近谱,以求解二维伴随QCD。通过简化该方法,我们在所有部分子区构造了完整的渐近本征函数集,并在基函数方法中用它来求全理论的谱。我们能够重现先前结果,包括在超对称点处费米子与玻色子质量的简并,并理解无质量理论中最低态的性质。此处采用的方法在固定部分子数下是连续的,因此与标准(类DLCQ)表述互补。尽管其局限于相当小的部分子数,它仍可用于以独立方式测试和验证其他框架的结论。

英文摘要:

We apply a method ("eLCQ") to find the asymptotic spectrum of a Hamiltonian from its symmetries to two-dimensional adjoint QCD. Streamlining the approach, we construct a complete set of asymptotic eigenfunctions in all parton sectors and use it in a basis-function approach to find the spectrum of the full theory. We are able to reproduce previous results including the degeneracy of fermionic and bosonic masses at the supersymmetric point, and to understand the properties of the lowest states in the massless theory. The approach taken here is continuous at fixed parton number, and therefore complementary to standard (DLCQ-like) formulations. Despite its limitation to rather small parton numbers, it can be used to test and validate conclusions of other frameworks in an independent way.
