论文摘要
我们提出了针对核子质量和$δ$共振的主要校正的晶格计算。这些是在QCD+QED中以$ 1 $ ST订单获得的，在Isospin中断参数中$α_{EM} $，电磁耦合以及$ \ frac {\ hat {\ hat {m} _d- {\ hat {m hat {m}}}} $}夸克。
We present a lattice calculation of the leading corrections to the masses of nucleons and $Δ$ resonances. These are obtained in QCD+QED at $1$st order in the Isospin Breaking parameters $α_{EM}$, the electromagnetic coupling, and $\frac{\hat{m}_d - {\hat{m}}_u}{Λ_{QCD}}$, coming from the mass difference between $u$ and $d$ quarks.
