We attempt to explain the large ${\bar \Lambda}/\bar p$ ratios measured in heavy ion collisions at $12~{\rm A\cdot GeV}/c$ beam momentum within an hadronic framework. The ratios are large compared to corresponding ratios in $pp$ collisions,…

Cross sections for proton knockout observed in (e,e'p) reactions are apparently quenched by a factor of ~0.5, an effect attributed to short-range correlations between nucleons. Here we demonstrate that such quenching is not restricted to…
