Variables & Observables
Variables:
- Beam Energy
- RHIC delivered ?s = 56 AGeV and 130 AGeV
- Centrality of collision
- Multiplicity in the paddles is related to number of participants, Npart
Observables:
- dN/dh | |h|ə ( where h = - ln tan (q/2) )
- Charged particle density averaged over –1 < h < 1
- dN/dh | |h|ə / ( ?Npart?/2 )
- Particles produced per participant pair
- (dN/dh | |h|ə )130 / (dN/dh | |h|ə )56
- Scaling of density with energy
Results presented will be for most central collisions
