  A formalism for hadron production at high \pt in heavy-ion collisions has
been developed such that all partons hadronize by recombination. The
fragmentation of a hard parton is accounted for by the recombination of shower
partons that it creates. Such shower partons can also recombine with the
thermal partons to form particles that dominate over all other possible modes
of hadronization in the $3<p_T<8$ GeV range. The results for the high \pt
spectra of pion, kaon, and proton agree well with experiments. Energy loss of
partons in the dense medium is taken into account on the average by an
effective parameter by fitting data, and is found to be universal independent
of the type of particles produced, as it should. Due to the recombination of
thermal and shower partons, the structure of jets produced in nuclear
collisions is different from that in $pp$ collisions. The consequence on
same-side correlations is discussed.
