STAR Research
Solenoidal Tracker at RHIC (Relativistic Heavy Ion Collider)
Massive detector Monitors and identifies ions particles
after collision Over 400 scientists and engineers
from 33 institutions in 7 countries.
Purpose
• Understanding of universe in first moments of creation
• Understanding of physical world• To obtain a fundamental understanding of the
structure of interactions between particles called hadrons, which are made of quarks and gluons.
• To investigate the behavior of matter at high energy densities.
• To look for signs of quark-gluon plasma.
Quark-Gluon Plasma
Inside protons and neutrons Gluons hold quarks
together. Protons always
have two "up" quarks and one "down" quark, while neutrons have two "down" quarks and
an "up" quark.
