1 Theme Group 2- Theory Elementary Particle Physics, Gravitation Theory and Theoretical Quarks, Hadrons and Nuclei Theme Group 2 March 2005

2 Theme Group 2 -Theory Elementary Particles (7 faculty, 2 post docs, 10 students, NSF,DOE) Supersymmetry, Supergravity and Grand Unification Neutrino Mass, CP and Flavor Physics Superstring Theory and Applications Problems in Cosmology Gravitation Theory (4 faculty, 6 post docs, 7 students, NSF,..) Geometry and topology in general relativity Gravitational wave physics Quantum, Stochastic and Semiclassical Gravity Quantum gravity phenomenology Theoretical Quarks, Hadrons and Nuclei (4 faculty, 2 post docs, 6 students, DOE) Effective Field Theories Large N QCD Hadron Structure, Spin Physics Lattice QCD Theme Group 2 March 2005

3 Theme Group-2: Theory Synergy and interaction Between the different groups (i) EP/GT: cosmological issues such as black hole physics, cosmological constant etc. (ii) EP/TQHN: Neutrino physics and QCD (iii) Theme Group 2: Th/Ex. B-physics, LHC, Neutrino physics. (iv) B. L. Hu of GT has started the QCI group that interacts with the AMO and superconductivity experimental group at UMCP, the atomic physics theory groups at NIST and Keith Schwab’s group on elecromechanics at LPS Theme Group 2 March 2005

4 Theme Group 2 Theory Common Issues
Cosmology Initiative proposal Theme Group 2 –Theory members unanimously feel that there is an urgent need for a dedicated Cosmology Theory Group and recommend that the department initiate one. Cosmology is exciting and rapidly developing, driven by new observations. Start with 2 to 3 junior or mid-career faculty (a past attempt to hire a senior “superstar” was not successful). A new cosmology group should resonate with Theme Group 2 Theory activities UMD astronomy program and NASA/Goddard Theme Group 2 March 2005

5 Theme Group 2 Theory Common Issues
Better Graduate Student Support by the University TA support for theory research has declined over the years affecting student quality. Theme Group- theory members urge that there be more sustained graduate student (TA/Fellowship) support by the University. Theme Group 2 March 2005

6 Theme Group 2 Theory Common Issues
Need for both more space and quality space Present locations of various subgroups of Theme Group 2 (theory) is not conducive to effective interactions . Quality of both faculty, visitor and student office space needs improvement. Theme Group 2 March 2005
