GlueX Project: Observing Exotic Mesons in Nuclear Physics

The GlueX Project at UConn Mentor Connection, led by Dr. Richard Jones, aims to study quarks, gluons, and confinement by creating and observing exotic mesons. This project, starting in 2014 at Thomas Jefferson National Accelerator Facility, will use a polarized beam and liquid hydrogen target to analyze final particles and radiation data. The process involves using electron beam diamond wafer to produce polarized photons that interact with mesons and detectors. Coherent bremsstrahlung, a radiation phenomenon, is key in this research, requiring precise crystal alignment and specific wavelengths. The reciprocal lattice vectors are used to interpret diffraction in crystals. This project promises to collect a massive amount of data and uncover forces along the gluon flux tube.

  1. Nuclear Physics Part 2: The GlueX Project UConn Mentor Connection Mariel Tader Mentor: Dr. Richard Jones

  2. The Project • Thomas Jefferson National Accelerator Facility • The collaboration • Will be the first to observe and study exotic mesons • Will begin 2014 UConn Mentor Connection 2010, Mariel Tader

  3. GlueX hopes to learn about quarks, gluons, and confinement by creating exotic mesons • How we “see” the gluons: Polarized beam liquid hydrogen target exotic mesons final particles and radiation data deciphered UConn Mentor Connection 2010, Mariel Tader

  4. The Process • Electron beam diamond wafer polarized photons hit mesons detectors UConn Mentor Connection 2010, Mariel Tader

  5. Bremsstrahlung • German for “braking radiation” • A radiation particle interacts with atoms and creates more radiation, while losing the corresponding energy Atom UConn Mentor Connection 2010, Mariel Tader

  6. Coherent Bremsstrahlung • Requirements: • Must be in a crystal • Particle/crystal must be in correct alignment • A few specific wavelengths are prevalent, “peaks” UConn Mentor Connection 2010, Mariel Tader

  7. Reciprocal Lattice Vectors • Bravais Lattice: repeating crystalline arrangements of points • Reciprocal Lattice: made from the vectors perpendicular to three of the vectors of the original lattice • Used as a simple geometric model that can interpret diffraction in crystals UConn Mentor Connection 2010, Mariel Tader

  8. Thank You for Listening • Questions? • Interesting Facts: • Within the detector’s first year, it will collect more data than all existing data of this type by several orders of magnitude • The forces along the gluon flux tube are about 16 tons UConn Mentor Connection 2010, Mariel Tader
