有效场论(EFT)方法在核系统中的应用提供了严格估计核哈密顿量中不确定性的机会。然而,这只是基于核EFT的计算所预测的可观测值的不确定性的一个来源。我们讨论了在这种计算中的不确定性量化的目标,并概述了一个配方,以获得统计上有意义的误差棒的预测。我们认为,理论错误的不同来源可以占贝叶斯框架内,我们说明使用玩具模型。
The application of effective field theory (EFT) methods to nuclear systems provides the opportunity to rigorously estimate the uncertainties originating in the nuclear Hamiltonian. Yet this is just one source of uncertainty in the observables predicted by calculations based on nuclear EFTs. We discuss the goals of uncertainty quantification in such calculations and outline a recipe to obtain statistically meaningful error bars for their predictions. We argue that the different sources of theory error can be accounted for within a Bayesian framework, as we illustrate using a toy model.
