Charmed spectroscopy from a nonperturbatively determined relativistic heavy quark action in full QCD

Huey-Wen Lin

摘要:

我们提出了一个初步的计算的粲介子光谱使用的2+1味域壁费米子晶格配置目前正在产生的RBC和UKQCD合作。计算使用3参数,相对论性重夸克作用与非微扰确定的系数。我们还将展示一个步骤,确定这些系数的非微扰使用一系列的淬火,规范场系综产生的三个不同的晶格间距的缩放程序。

英文摘要:

We present a preliminary calculation of the charmed meson spectrum using the 2+1 flavor domain wall fermion lattice configurations currently being generated by the RBC and UKQCD collaborations. The calculation is performed using the 3-parameter, relativistic heavy quark action with nonperturbatively determined coefficients. We will also demonstrate a step-scaling procedure for determining these coefficients nonperturbatively using a series of quenched, gauge field ensembles generated for three different lattice spacings.
