The Photon Multiplicity Detector will be installed at STAR covering
the region 2.3< eta < 3.5. It has a overlap with FTPC which gives the
charged particle multiplicity in STAR. PMD will measure the multiplicity and spatial
distribution of photons on an event by event basis. Combining this information with
charged particle multiplicity PMD will address the following broad topics of physics:
- Determination of the reaction plane and the probes of thermalization via studies of
azimuthal anisotropy and flow.
- Critical phenomena near the phase boundary leading to fluctuation in global variables
like multiplicity and pseudorapidity distribution.
- Signals of chiral symmetry restoration (e.g. DCC) through the measurement of charged
particle multiplicity (Nch)in a common part of phase space and study the
observables Ngamma and Ngamma/Nch with full azimuthal
coverage and with momentum selection of charged particles.
