Studies of Proton Momentum Distribution in $^{\mathrm{4}}$He

Experimental cross sections for the $^{\mathrm{4}}$He(e,e'p)X reaction up to a missing momentum of 0.632 GeV/$c$ at x$_{\mathrm{B}}=$1.24 and Q$^{\mathrm{2}}=$2 (GeV/$c)^{\mathrm{2}}$ will be presented. The data are compared to Relativistic Distorted Wave Impulse Approximation (RDWIA) calculations for $^{\mathrm{4}}$He(e,e'p)$^{\mathrm{3}}$H channel. Significantly more events in the triton mass region are measured for p$_{\mathrm{m}}$ \textgreater 0.45 GeV/$c$ than are predicted by the theoretical model, suggesting that the effects of initial-state multi-nucleon correlations are stronger than expected by the RDWIA model.
