"The Emergence of Jet Dominance in gamma-p Interactions at Fixed-Target
Energies"
Speaker: Dr. Don Lincoln
Fermilab
In Fermilab experiment E683 we have used a large solid angle
calorimeter to study the production of hadronic events with large
transverse energy in gamma-p and pi-p collisions at center-of-mass
energies from 20 to 25 GeV. We observe a sudden shift in gamma-p event
topology with increasing transverse energy, indicative of the emergence
of jet dominance. This is the first observation of such a shift in
event topology in fixed-target interactions. pi-p interactions in the
same kinematic region and under identical triggering conditions exhibit
only a slight shift in event topology.
