论文摘要
我们介绍了一个正在进行的项目的状态，该项目旨在包括夸张质量质量的非分类和电磁相互作用在低寓言八位位和解剖baryon块的计算中产生的均质校正。我们的最终目标是对晶格量表进行精确确定，包括破裂的效果。我们将扰动形式主义应用于isospin-Ammortric $ n_f = 2+1 $ cls emembles。我们显示了Baryon质量的结果，直到两种合奏中的$M_π\大约290 \，\ text {Mev} $和$M_π\ oft215 \，\ oft text {mev {mev {mev {mev {mev} $，在$ a \ a \ aif0.0.076 \ texts $ a的lattice间距上，
We present the status of an ongoing project aimed at the inclusion of isospin-breaking corrections arising from the non-degeneracy of the light quark masses and electromagnetic interactions in calculations of the low-lying octet and decuplet baryon masses. Our ultimate goal is to perform a precision determination of the lattice scale including isospin-breaking effects. We apply the perturbative formalism to isospin-symmetric $N_f=2+1$ CLS ensembles. We show results on baryon masses up to leading order in isospin-breaking corrections on two ensembles with $m_π\approx290\,\text{MeV}$ and $m_π\approx215\,\text{MeV}$ at a lattice spacing of $a\approx0.076\,\text{fm}$.
