Neglecting implicit f-dependence
- Negligible if x?-K? correlations (due to transverse flow, opaqueness) small compared to thermal smearing
- no restriction on longitudinal flow
- may be checked via consistency relations ?
Smn(f) = Smn “Same source viewed from all angles f”
Implicit f-dependence weak compared to explicit f-dependence
Contrast with KT dependence from azimuthally symmetric case
- implicit KT dep. need not vanish @ KT=0
- explicit KT-dependence weighted with (generally small) b?t
- explicit KT-dependence vanishes at K? ? 0
Note: usually, neglecting x-K correlations is “boring”, but we show that there is something exciting that was overlooked until now!
