Probing for high momentum protons in ⁴He via the ⁴He(e, e'p)X reaction

Experimental cross sections for the ⁴He(e, e' p)X up to Pmiss = 0.632GeV/c at x_B = 1.24 and
Q² = 2(GeV/c)²  are reported. The data was taken in Hall A of Jefferson Lab during the E08009 experiment. My contribution to the project was to the data quality check and acceptance studies, as well as in comparing the Physics results to theoretical predictions. Experimental cross section is compared to Relativistic Distorted Wave Impulse Approximation(RDWIA) calculations for ⁴He(e,e'p)X reactions. Signicantly more events in the triton mass region are measured for P_miss > 0.45GeV/c than are predicted by the theoretical model.
