| 英文摘要 | In this paper, we apply the Maximum Entropy Method to estimate the proton radius and determine the valence quark distributions in the proton at extremely low resolution scale Q(0)(2). Using the simplest functional form of the valence quark distribution and standard deviations of quark distribution functions in the estimation of the proton radius, we obtain a quadratic polynomial for the relationship between the proton radius and the momentum fraction of other non-perturbative components in the proton. The proton radii are approximately equal to the muonic hydrogen experimental result r(p) = 0.841 fm and the CODATA analysis r(p) = 0.877 fm when the other non-perturbative components account for 17.5% and 22.3% respectively. We propose "ghost matter" to explain the difference in other non-perturbative components (4.8%) that the electron can detect. |
