Abstract
The Relativistic Heavy Ion Collider (RHIC) is a unique
hadron collider machine. It collides many different colliding
systems, e.g., nucleon-nucleon, nucleon-nucleus, and
nucleus-nucleus systems. It is the only worldwide collider
for polarized proton-proton collisions. Along RHIC’s ring
(2.4 mile in circumference) there are currently two
experiments, STAR and PHENIX detectors.
The main purpose for such experiments is to detect a
univocal signature for a Quark-Gluon Plasma (QGP) phase.
The QGP is a phase of matter believed to exist in the first
second of our Universe. One of the important signatures of
the QGP is the rate of the heavy quarks productions in the
nucleus-nucleus collision compared to these in nucleonnucleon
collisions. The theoretical models-experimental
observations comparison has indicated the necessity of
separating the contributions from different heavy quarks to
the total production rates. STAR experiment has taken the
role in such heavy quarks physics upgrading the detector
with the Muon Telescope Detector (MTD). The aim of this
work is to explore the physics capability of STAR
experiment after “partial” installation of the Muon
Telescope Detector (MTD), and particularly in separating
between the charmonium and bottonium contributions. The thesis coming in three chapters: The 1st chapter
describes some theoretical aspects such as the standard
model, the quark gluon plasma (QGP) and its signatures.
The 2nd chapter explores the different experiments at RHIC
and focuses on STAR experiment sub-detectors specially
the Time Projection Chamber (TPC) and the MTD. The last
chapter consists of two parts, the simulation analysis and the
real data analysis. In the simulation analysis we study the bmeson
efficiency, the primordial J/ rejection power and
the contamination of the B-meson signal at different decay
length cuts. In the real data analysis we examine the ability
of the MTD to identify the muons through applying cuts on
the difference between the primary vertex position along the
beam axis and its projected value at the MTD.
