The pictures in this directory are based on neXus2 MC simulations of RHIC Au-Au 
events at 100x100 GeV/u provided by Klaus Werner and coworkers from the 
University of Nantes.

The images were made by Tom Trainor using the visualization tool DSV produced by 
Duncan Prindle, both from the University of Washington.

Notes:

Color scheme:

number - point - track - particles

0 - dk blue - dk green - all else (exotic?)

1 - nothing assigned

2 - magenta - cyan - partons

3 - yellow - dk blue - lighter than mesons

4 - cyan - magenta - pions

5 - orange - lt green - kaons

6 - red - yellow - nucleons

7 - lt green - orange - strange baryons

8 - dk green - red - all heavier hadrons

Images:

fireball0.gif - fireball image focussing on the central region, 
viewing in the midplane to show the momentum `flow.' Point positions are 
coordinate rapidities, vectors are momentum rapidities.

fireball00.gif - as previous, an axial view to show nearly random thermal 
transverse momentum.

fireball01.gif - as previous, but closer view.

fireball000.gif - zoom far out along z to show annuli of pions and partons at 
very large radii.

fireball1.gif - as previous, but in a perspective view.

fireball2.gif - zooming out we see sphere of light stuff (yellow pts) and 
primordial(?) nucleons (red pts) parked out at huge rapdities (63!)

fireball3.gif even further out showing annuli of partons and pions at huge 
radial rapidities (up to 23).

fireball4.gif zoom in on central fireball

fireball5.gif turn off pions to show what is underneath, esp. strange 
particles.

fireball6.gif turn off pions to show what is underneath, esp. strange 
particles.

momentum1.gif momentum space done in radial and longitudinal rapidities

xtspace1.gif config space with radial and axial rapidities in horizontal 
and time rapidity in vertical. Shows successive waves of particle 
production along a 3D light cone. Pions are turned off

xtspace2.gif same but looking along the radial coordinate - conventional 
light cone

xtspace3.gif looking along the axial rapidity to see radial expansion

xtspace4.gif looking up from below the space rapidity plane along the 3D 
light cone. Pions are turned off.

ptspace1.gif hybrid space with axial and transverse momentum rapidities in 
horizontal plane and time rapidity on the vertical. Looking here along the 
pt rapidity.

ptspace2.gif perspective view looking down on momentum plane, with hint of 
kinematic constraint.

ptspace3.gif looking along time rapidity at momentum rapidity plane, pions 
turned on here, off for other ptspace images.

ptspace4.gif looking along pz rapidity to show time evolution of pt space.
