Transverse and radial how measurements are presented for A hyperons along w
ith A-P correlations from Au + Au collisions at AGS energies. The flow meas
urements are compared with those of co-produced protons. The measurements i
ndicate that A hyperons flow consistently in the same direction as protons
but with a smaller magnitude for all beam energies. Comparisons with RQMD c
alculations show that the experimentally determined Lambda sideward flow is
consistently larger compared with the calculated value obtained from scatt
ering processes only. The experimental transverse flow ratio Lambda /P is c
onsistent with predictions (similar or equal to (2)/(3)) of the quark count
ing rule at 2 A GeV but is found to decrease with increasing beam energy. T
hese observations may be related to the detailed features of the A-nucleon
potential for the nuclear densities produced. At 6 A GeV, np correlation fu
nctions are observed to be essentially flat (within statistical uncertainty
), indicating little or no correlation between As and co-produced protons.
This suggests that As may have a spacetime emission pattern which is differ
ent from that for protons. Further evidence from radial flow measurements a
lso indicates that 6 A GeV A hyperons (at mid-rapidity) do not share the sa
me emitting source characteristics as coproduced protons.
