Professor. Ph.D. Columbia University, 1963. Fellow, American Physical Society. Member American Association for the Advancement of Science.

My group has made accurate tests of the Standard Model using polarized electron annihilations with positrons in the Z energy scale at the Stanford Linear Accelerator Center. I am now a member of the BaBar Collaboration that is studying the CP violation phenomena in the b quark sector. In particular I and my students have determined the decay B-> Psi(2S)Ks branching ratio and developed a method to associate photons into pi-zeros in such a manner that we reduce the background. I am involved in the study of the science potential of the International high energy Linear Collider (ILC). The purpose of the collider is to study, in detail, the physics beyond the Standard Model and the possibility of uncovering signals related to supersymmetry. My group has proposed and is studying, both via hardware and simulation efforts, a new geometric design of a scintillator based electromagnetic calorimeter that maintains its excellent energy resolution but improves substantially the determination of the photon direction. I am a member of the international POWER group studying the usefulness of positron polarization in such a collider. I am a co-leader of the Supersymmetry study group in the American Linear Collider Physics Group (ALCPG).


  • We and collaborators are hosting a meeting of the Deep Underground Science and Engineering Laboratory (DUSEL) collaboration during January, 2005 in Boulder. The purpose is to continue our study on how to build such a Laboratory that the NSF is considering to fund its construction in the near future. Colorado's Henderson mine in the Rockies will be proposed (by a collaboration of the Colorado Arapahoe Project, the Colorado School of Mines, Colorado State University, and the University of Colorado Boulder) as such a site.

  • My group and collaborators are hosting a workshop, in August 2005, in Snowmass, Colorado, of the International Linear Collider Collaboration. The purpose is to continue to develop the detector and associated accelerator elements.
