  We study the production of hadrons in Au+Au collisions in the region
$0.6<x_F<1.2$, which we refer to as the trans-fragmentation region (TFR), since
it corresponds roughly to $\eta'>0$, where $\eta'=\eta-y_{\rm beam}$, depending
on $p_T$. We show how hadrons can be produced in that region when the
hadronization process is parton recombination. The inclusive $x$-distributions
for proton and pion production are calculated with momentum degradation taken
into account. The results show that the proton yield is significantly higher
than that of the pions in the TFR. Without particle identification the existing
data cannot be used for comparison with our result on the $p/\pi$ ratio.
Without $p_T$ determination it is not feasible to relate the $x$ distribution
to the experimental $\eta'$ distribution. Nevertheless, on theoretical grounds
we have shown why the production of hadrons in the TFR is not forbidden by
momentum conservation.
