Description
We present an update of the Miettinen-Pumplim (MP) model for diffractive excitation for proton-proton ($pp$) and antiproton-proton ($\bar{p}p$) scattering considering recent LHC data. The energy dependence of the total, elastic, and diffractive cross sections are analyzed and compared to data. The implications of the diffractive excitation in proton-nucleus ($pA$) collisions are also discussed for different nuclei. We used the MP model to derive the main quantities present in the treatment of the diffractive excitation in $pA$ collisions. We demonstrate that the effect of fluctuations decreases at larger energies and heavier nuclei. We also compare our results with the predictions for the proton dissociation induced by photon interactions.
