Opposing average tilts in p, x and the physics of p flow
RQMD w/ meanfield: Au(2GeV)Au, b=3-7 fm
- coordinate-space tilt in positive direction
- Antiflow reflects dense low-|z| region
- p from dilute large-|z| show positive flow
transport model exhibits weak p “antiflow,” similar to observation (Kintner et al. PRL 78 4165, 1997)
Bass et al [PLB 302 381 (93), PRC 51 3343 (95)]:
pion anisotropies ~ 2 AGeV due to
not absorption (pNN?DN ?NN)
experimental handle through tilt?
