Professor Eisenstein received his Ph.D. in Physics from Columbia University
in 1964, after receiving an A.B. and an A.M. in physics there in 1959
and 1961, respectively. He was a research fellow and lecturer at Harvard
from 1964-1967, when he joined the physics faculty at Illinois. Professor
Eisenstein has made important contributions in a broad number of areas
in experimental particle physics, from the depolarization of muons in
solids to the properties of quarks. Although he has designed and built
components of detectors, his primary efforts have been in the analysis
of data. Research Area: Experimental high-energy physics; weak interactions of B mesons. Description of Current Research: Elementary Particle Experiment The two main thrusts of high-energy physics research are to determine the form and strength of the fundamental interactions in nature and to determine the properties of the particles that enter into these interactions. The two main thrusts of elementary particle physics research are to determine the form and strength of the fundamental interactions in nature and to determine the properties of the particles that enter into these interactions. Our group presently works on experiments at Fermilab, Cornell University, and CERN. We participated in the discovery of the top quark and expect to observe time reversal symmetry violation in B-meson decays. In the future, we hope to observe the Higgs boson, thought to be responsible for the existence of mass. Study of Heavy Flavors at the Cornell Electron Storage Ring (CESR) We use the CLEO detector at CESR to study the properties of the lepton and of particles containing the b and c quarks. These studies allow us to perform stringent tests of the standard model of the fundamental interactions. This is the modern equivalent of the atomic physics experiments performed early this century to test quantum mechanics. We are participating in a major upgrade of the CLEO detector, which will effect dramatic improvements in the experiment’s resolution and statistical precision. One of our goals is to determine whether or not the standard model can account for the small matter-antimatter asymmetry present in our universe. CLEO Experiment at CESR The CLEO experiment at the Cornell electron positron storage ring (CESR) studies the properties of the bottom and charmed quarks and the tau lepton. The primary goals of these studies are: (1) the understanding of the origin of the Cabibbo-Kobayashi-Maskawa (CKM) mixing matrix, for which no dynamical theory exists; (2) understanding of time reversal symmetry violation, which appears to be a necessary prerequisite to the observed matter-antimatter asymmetry of the universe; and (3) tests of the "standard model" of particle physics, whose very precise predictions have been tested very accurately, but which, nonetheless, is known not to be correct. Deviations from these predictions will tell us where the flaw lies. Recent Publications: Rosner, JL, et al. Observation of the hc(1P1) state charmonium. Phys. Rev. Lett. 95, 102003-1-5 (2005).
