Maria Grazia Pia, Marcia Begalli, Anton Lechner, Lina Quintieri, Paolo Saracco

摘要:

通过一个具体的应用实例讨论了认识不确定性如何影响蒙特卡罗模拟结果的问题:低能质子纵向能量沉积剖面的模拟。研究了各种电磁和强子物理模型,并分析了它们的影响。可能的系统性影响突出。结果确定的要求,能够减少认识的物理模型中的不确定性的实验测量。

英文摘要:

The issue of how epistemic uncertainties affect the outcome of Monte Carlo simulation is discussed by means of a concrete use case: the simulation of the longitudinal energy deposition profile of low energy protons. A variety of electromagnetic and hadronic physics models is investigated, and their effects are analyzed. Possible systematic effects are highlighted. The results identify requirements for experimental measurements capable of reducing epistemic uncertainties in the physics models.
