论文摘要
我们使用OpenQ $^\ star $ d代码对RC $^\ star $ Collaboration的持续工作进行更新,以使用C $^\ star $边界条件生成完全动态的QCD+QED配置。将模拟调整为pions $ m_ {π^\ pm} \大约400 $ meV的U-对称点($ M_D = m_s $)。 The splitting of the light mesons is used as one of three tuning observables and fixed to $m_{K^0} - m_{K^\pm} \approx 5$ MeV and $m_{K^0} - m_{K^\pm} \approx 25$ MeV on ensembles with renormalized electromagnetic coupling $α_\mathrm{R} \approx α_\ mathrm {phys。} $和$α_\ mathrm {r} \大约5.5α_\ mathrm {phys。} $。我们将讨论有关我们调整策略的一些细节,并介绍介子和重子群众的计算。最后,我们还将为我们的模拟提供成本分析。有关有限体积效果和调整的更多技术细节,请参见A. cotellucci的诉讼程序。
We give an update on the ongoing effort of the RC$^\star$ collaboration to generate fully dynamical QCD+QED configurations with C$^\star$ boundary conditions using the openQ$^\star$D code. The simulations are tuned to the U-symmetric point ($m_d=m_s$) with pions at $m_{π^\pm}\approx 400$ MeV. The splitting of the light mesons is used as one of three tuning observables and fixed to $m_{K^0} - m_{K^\pm} \approx 5$ MeV and $m_{K^0} - m_{K^\pm} \approx 25$ MeV on ensembles with renormalized electromagnetic coupling $α_\mathrm{R} \approx α_\mathrm{phys.}$ and $α_\mathrm{R}\approx 5.5 α_\mathrm{phys.}$ respectively. We will discuss some details concerning our tuning strategy and present the calculation of the meson and baryon masses. Finally, we will also present a cost analysis for our simulations. More technical details on finite-volume effects and the tuning can be found in A. Cotellucci's proceedings.
