摘要

EQCD是一个包含SU(3)和伴随标量的三维玻色子理论，它有效地描述了热QCD的红外、非微扰扇区，并且非常适合于晶格研究。我们通过确定$\mathcal{O}(a)$匹配中的最终未知系数来改进晶格和连续体EQCD之间的匹配，这是一种加性标量质量重整化。我们通过使用EQCD的对称破缺相变线作为常数物理线来进行数值计算。这为在该理论范围内精确地研究横向动量扩散系数C(q_\perp)$奠定了基础。

Full $\mathcal{O}(a)$ improvement in EQCD

EQCD is a 3D bosonic theory containing SU(3) and an adjoint scalar, which efficiently describes the infrared, nonperturbative sector of hot QCD and which is highly amenable to lattice study. We improve the matching between lattice and continuum EQCD by determining the final unknown coefficient in the $\mathcal{O}(a)$ matching, an additive scalar mass renormalization. We do this numerically by using the symmetry-breaking phase transition line of EQCD as a line of constant physics. This prepares the ground for a precision study of the transverse momentum diffusion coefficient $C(q_\perp)$ within this theory.
