Query: Forward Production With Large p/\pi Ratio and Without Jet Structure at
  Any p_T   Particle production in the forward region of heavy-ion collisions is shown to
be due to parton recombination without shower partons. The regeneration of soft
partons due to momentum degradation through the nuclear medium is considered.
The degree of degradation is determined by fitting the $\bar p/p$ ratio. The
data at $\sqrt s=62.4$ GeV and $\eta=3.2$ from BRAHMS on the $p_T$ distribution
of average charged particles are well reproduced. Large proton-to-pion ratio is
predicted. The particles produced at any $p_T$ should have no associated
particles above background to manifest any jet structure.
