  1. The Large Hadron Collider

  2. High Energy LHC Physics Collider Experiment: Yuri Gershtein, Eva Halkiadakis, Mohan Kalekar, Amit Lath, Steve Schnetzer, Sunil Somalwar + students and postdocs Collider Theory: Tom Banks, David Shih, Matt Strassler, Scott Thomas, … + students and postdocs

  3. High Energy LHC Physics Rutgers has a Unique Strength among US institutions in the close collaboration between Experimental and Theoretical High Energy Physics Groups The High Energy Experimental Group has extensive experience in Instrumentation and New Physics searches at the Fermilab Tevatron Collider, and is highly regarded within the field The High Energy Theory Group is already one of the leading Centers for LHC phenomenology On Our Current Trajectory the combined LHC effort at Rutgers can be at least comparable to that at Berkeley, Stanford, and Princeton, and better than the programs at Harvard, Caltech, Chicago, Yale, and Penn

  4. High Energy LHC Physics Collider Physics Funding: 1.2 M/yr NSF + DOE Students/Postdoc/Faculty Placement -> Faculty: Berkeley (Kachru, Luk, Horava) Stanford (Silverstein, Shenker) Harvard (Motl) Institute for Advanced Study (Seiberg, Maldacena) Columbia (Kabat) Rutgers (Halkiadakis) Fermilab (Flaugher, Sexton) Florida State (Askew) San Diego (Intriligator) Northwestern (Anastassov) Simons Center - Stony Brook (Douglas) Utah (Bergman) Karlsruh (Ratnikov)

  5. Large Hadron Collider Largest Scientific Experiment in History

  6. Large Hadron Collider 1232 Super Conducting Dipole Magnets ½ nanogram in Beam – Kinetic Energy of 100,000 Ton . Aircraft Carrier at Cruising Speed

  7. Large Hadron Collider Proton-Proton Collisions at 14 Trillion Electron Volts Probe Energies Equivalent to 10-12 second After Big Bang The Physics of the Higgs Sector Responsible for*** the Origin of Mass will Become Manifest Possible - Uncover new Symmetries and Forces of Nature, Produce new Particles, Unlock Quantum Dimensions, Produce and Measure Properties of Dark Matter Particles, Discover the Origin of Cosmological Matter-Antimatter Asymmetry Fundamental Physics - Poised to Enter a New Era of Discovery !!! Begin Operations November 2009
