00925njm 22002777a 4500 dc Udías Moinelo, José Manuel author otros, ... author 2022-06-22 Experimental cross sections for the He-4(e, e'p)X reactions in the missing energy range from 0.017 to 0.022 GeV and up to a missing momentum of 0.632 GeV/c at x(B) = 1.24 and Q(2) = 2 (GeV/c)(2) are reported. The data are compared to relativistic distorted-wave impulse approximation calculations for the He-4(e, e'p)H-3 channel. Significantly more events are observed for p(m) >= 0.45 GeV/c than are predicted by the theoretical model, and striking fluctuations in the ratio of data to the theoretical model around p(m) = 0.3 GeV/c are possible signals of initial-state multinucleon correlations. 2469-9985 10.1103/PhysRevC.105.064003 https://hdl.handle.net/20.500.14352/72965 http://dx.doi.org/10.1103/PhysRevC.105.064003 https://journals.aps.org/ Probing for high-momentum protons in He-4 via the He-4(e, e ' p)X reactions
