Using Bayesian inference, we determine probabilistic constraints on the parameters describing the fluctuating structure of protons at high energy. We employ the color glass condensate framework supplemented with a model for the spatial structure of the proton, along with experimental data from the ZEUS and H1 Collaborations on coherent and incoherent diffractive production in e+p collisions at HERA. This data is found to constrain most model parameters well. This work sets the stage for future global analyses, including experimental data from e+p, p+p, and p+A collisions, to constrain the fluctuating structure of nucleons along with properties of the final state.

波动质子形状的贝叶斯推断
使用贝叶斯推理,我们确定了描述高能质子波动结构的参数的概率约束。我们采用彩色玻璃凝聚体框架,辅以质子空间结构模型,以及来自 ZEUS 和 H1 合作的相干和非相干衍射实验数据在 HERA 生产 e+p 碰撞。发现该数据可以很好地约束大多数模型参数。这项工作为未来的全局分析奠定了基础,包括来自 e+p、p+p 和 p+A 碰撞的实验数据,以约束核子的波动结构以及最终状态的特性。
