Current Research I

Hardware and Software for PHENIX Muon Arm Detectors

Heavy Flavor Physics Studied through Single Muon Production The analysis method has been developed primarily by the

Tennessee/ORNL team Charm Cross Sections in p+p at sqrt(s) = 200 GeV (Run 2)


Current Research II

Heavy Flavor Production through Single Muon detection for p+p at sqrt(s) = 200 (Run 5)

Donald Hornback (Thesis project)

Heavy Flavor Production through Single Muon detection for Cu+Cu at sqrt(sNN) = 200 (Run 5)

Irakli Garishvili (Thesis project)

Heavy Flavor Collective Flow for Cu+Cu at sqrt(sNN) = 200 (Run 5)

Joshua Hamblen (Post-doc)

Further development of background subtraction techniques

Hadronic punch trough Decay muons from non-heavy-flavor particles (Pions, Kaons, ..)


Impact on RHIC Research (2007-2012)

Overall proposed effort distribution: PHENIX 100% 60% ALICE 0% 40%

PHENIX Continued heavy flavor data analysis (single muons) Mature analysis methods that will require much less work

from now on to produce publishable results Ken Read will continue as sub-system manager of the MuId Instead of 2-3 students on PHENIX, it will be 1-2. All

students will take shifts and learn to be MuId experts. We will participate in the Silicon Vertex Upgrade

• Testing of readout electronics for the barrel strip layers• Installation and commissioning• In particular, new analysis using the Silicon vertex Detector information

Many similarities to the STAR and ALICE analysis


Proposed ALICE Physics Research by U. Tennessee

1. total heavy flavor production cross sections in p+p and heavy ion reactions

2. heavy flavor jet transverse momentum spectra (jet suppression issues)

3. azimuthal anisotropical emission of heavy flavor jets relative to the reaction plane (v2 values)

1. transport coefficients 2. the ratio of viscosity over entropy density for the medium.

4. modifications of heavy flavor jet fragmentation functions in the presence of a hot and dense partonic medium studied through tagged electrons

5. studies of charmonium and bottomonium at high transverse momentum through the observation of a trigger electron in the EMCal.


Detector Deliverables

In collaboration with ORNL (Awes) test, calibrate, install, and commission the EMCal readout electronics

Test Beam participation EMCal Calibration Establish the operational characteristics of the readout

modules and to test the complete final electronics chain.

Josh Hamblen will be ~2 months at CERN (May-June) for learning and testing ALICE PHOS electronics as preparation for EMCal electronics testing.


EMCal Calibration
