**Notes:**
I should add a slide with dn/deta/npart/2 vs npart ditto for ET and ditto for their ratio. 

##  Are there fluctuations beyond random?

-  Are there fluctuations beyond random?

- Event-by-event average pT (MpT) is closely related to ET

-  compare Data to Mixed events for random.

-  deviation expressed as:
- FpT= MpTdata / MpTmixed -1  ~ few %

-  due to jets see PRL **93**, 092301(04)

-  Non-Random fluctuations small ~few %

## RAA (0) AuAu:pp 200GeV High pT Suppression flat from 3 to 10 GeV/c !! 

-  PRL 91, 072301 (2003)

- Binary scaling

- Participant scaling

- Factor 5

**Large suppression in central AuAu - close to participant scaling at high P****T**

**Peripheral AuAu - consistent with N****coll**** scaling (large systematic error)**

**Flat R****AA******** ********E/E=const**
**Theory ********E=Const~ L****2**** **

**How high in p****T**** is********E/E=const ?**

## Particle ratios---inclusive and at high pT

- Particle ratios---inclusive and at high pT

- inclusive vs centrality-nothing much

- Au+Au sNN=200 GeV

- dramatic increase with centrality vs pT

- PRL **88**, 024301 (2002),  PRL **91**, 172301 (2003)

- but PRC **69** 034909 (2004) cited 122 times, so far

## protons: Ncoll scaling with centrality, radial flow

- PRL **91**, 172301 (2003)

- protons scale with Ncoll,  suppressed: why do we say p are anomalous ?

## QM0204 AuAu 200 GeV charm via e±

** ****Some data with 1.7 % X****0 ****converter added**
** ****converter only affects photonic component**

** ****converter effect is much greater at low p****T****, indicating **
**   ********  ****relatively much larger photonic component at low p****T**** **
**    ******** ****relatively smaller phtonic (i.e. larger non-photonic)**
**         ****component at higher pT (i.e. charm) **
**Reduced systematic erros. **

## BNL/PHENIX Group---PRIORITIES

-  Run and improve the detector, daq, etc. Take more and better data.
-  Publish all papers from Runs 2, 3, 4.
-  Determine whether medium at RHIC is `classical’ QGP, or what else?
-  thermal photons and leptons, J/Psi at mid-rapidity (rare events)
-  Upsilon and Drell-Yan---Detector can do it, just need luminosity.
-  Specific heat, thermal properties, fluctuations

-  Follow up on our discoveries to learn the properties of the actual medium (fluid?) and to study energy loss phenomenon in detail.
-  E ~const, then why is RAA flat vs pT?; is E~L2? Understand energy loss as a function of pT, particle type, quark flavor, mass, time (distance) in medium  studies vs centrality, angle to reaction plane, c.m. energy for identified particles and particle correlations hard and soft. Source of p/ anomaly? How about U+U collisions?
- Flow: do particles or quarks flow, charm flow, J/Psi flow, mach flow? Is charm suppressed in AuAu?
-  New phenomena in A+A, Pentaquark, Parity Violation?

## BNL/PHENIX Group---PRIORITIES-II

-  RHIC Spin Program
-  Gluon (spin) structure function by direct   10 < pT < 25 GeV/c
-  Flavor identified structure functions by Parity Violating W*l *
-  New Physics via Parity Violation in ~100 GeV jets.

-  RHIC Upgrades---PHENIX could operate as is
-  Higher Luminosity, Heavier Beams U+U, smaller diamond
-  Detector Upgrades---New Physics
-  HBD: allows low mass e+ e-: , , , continuum
-  SVX: Charm flow, suppression, AERC Pid to 20 GeV/c D->K, B meson? Conflict with J/Psi, single e, e+e- program which needs lots more int luminosity (Run 8 AuAu + probably more). Priority depends on how much more J/Psi low pT data is needed
-  Nose Cone Calorimeter: gluon structure function vs A at low x high pT  via +Jet: has never been measured, vital input for RHIC AA, vital for Color Glass Condensate physics

- v2 0  pending

- nucl-ex-0502009 to appear PRC

**0-20%**

**20-40%**

**40-90%**

**60.6 +- 11.8**

**55.7 +- 8.6**

- Not enough people to be able to contribute more directly but two of Hamagaki’s students: Taku Gunji, Fukutaro Kajihara consult with Takao Sakaguchi (former RICH expert) and ``officially” responsible to MJT while at BNL.

## Au+Au @ 62.4 GeV

**R****AA**** calculated using ISR data for pp reference.**
**Systematics could be greatly reduced with RHIC pp reference at 62.4 GeV! My first priority for Run 6!**

- 0-10%

- 10-30%

## Plot E(pT)/pT=Sloss vs centrality Bj(Npart)

- !

- PHENIX preliminary

## RAA (Sloss) 0 vs. Reaction Plane: E(/E)~L2   ? 

- RAA can be calculated as a function of angle w.r.t the reaction plane.
- RAA for 0 in AuAu
- Use RAA to calculate Sloss as a function of angle
- More detailed information about path length dependence!
- Run-4 data will add:
- Higher reach in pT
- The 
- Run-5 (CuCu) data:
- Different density and path length through medium

- AuAu 200

- PHENIX Preliminary Nice Result at QM2005

- Different systems, different s different pT, different particles until we understand medium effect and Energy Loss Theory

## Jet Structure-2 particle correlations-from CERN-ISR

- Back-angle correlations in AuAu display unusual shape!
- Indication of shock wave?
- If so this may measure the speed of sound in the medium!
- Run-4,5,8 needed to push to higher pT!
- Easier to deal with v2
- Narrowing correlation peaks

**PHENIX Preliminary**

-   Needs lots more data!

- Also jT, kT, fragmentation function, in pp dAu at QM2005

## Correlations-Fluctuations

- PHENIX: Au+Au √sNN=200GeV
- NBD fits vs 

- K. Homma and T. Nakamura
- +JTM+MJT

- Multiplicity distributions observed in Au+Au, d+Au and p+p collisions at PHENIX also conform to the negative binomial distribution.

## LHC-Atlas [BNL-HEP is US center]

- My main job is to keep everybody not thinking about LHC so as to discover everything there is to discover at RHIC
- Our group’s contribution is 25% of Sebastian White
-  ZDC
- Ultra-Peripheral (Coulomb)-``UPC” physics
- Special travel budget from Physics Dept funds
- Expect J/Psi measurement in UPC from PHENIX at QM2005 or soon afterwards.

## Future Plans-Same for Group and Collaboration

## ISSUE(S)$

## Issue-Manpower and current support

-  Constant $$$ Flat-Flat budgets from FY02-FY05 can not continue without seriously impacting Group Research (and Operations)
-  Increased level of effort would have the benefit of allowing the hiring of 1 or 2 more scientists or post docs which will allow the group to better keep up with the constant stream of data from RHIC while being able to devote some time to maintain their skills, attend seminars and keep up with other developments in the field
-  Moving support from Research to Operations can only be a one time correction. As new components are added to PHENIX money for support must increase. Support received by BNL/PHENIX group must be at least at constant effort (rather than constant dollars---flat-flat).

## CONCLUSION

-  The BNL PHENIX Group has demonstrated creativity as well as the ability to make high quality measurements of  systems ranging from p-p to Au+Au central collisions in the PHENIX detector.
-  We wish to continue these successes in order to characterize the hot medium produced at RHIC and to measure its properties using the probes we have successfully demonstrated and mastered (and probably new ones ...)
-  We look forward to many more years of great results and discoveries which we will be able to publish as well as to present at national and international meetings.
-  Our staff is highly recruited for faculty positions. We would like to be able to maintain or increase (+2 FTE) the present group size.
