A Measurement of the B0 --> J/psi pi+pi- Branching Fraction
The BABAR Collaboration, B. Aubert
We present a preliminary measurement of the branching fraction for the decay of the neutral meson into the final state J/. The data set contains approximately 56 milli…
Search for Direct CP Violation in Hyperon Decay
D. E. Jaffe, CLEO Collaboration
Using data collected with the CLEO II detector we have performed a search for direct CP violation in the hyperon system. CP violation gives rise to an asymmetry, A, between the…
From Accelerators To Asteroids
Martin L. Perl
In this talk I discuss the reach of traditional methods of elementary particle physics in five broad experimental areas. For each of these areas I inquire how that reach is, or mig…
The Search for Fractional Charge Elementary Particles and Very Massive Particles in Bulk Matter
Martin L. Perl, Valerie Halyo, Peter C. Kim +3
We describe our ongoing work on, and future plans for, searches in bulk matter for fractional charge elementary particles and very massive elementary particles. Our primary interes…
Certainty and Uncertainty in the Practice of Science: Electrons, Muons, and Taus
M. L. Perl
During the past one hundred years three related elementary particles - the electron, the muon, and the tau - were discovered by very different scientific techniques. The author, wh…
The Tau Lepton and the Search for New Elementary Particle Physics
M. L. Perl
This Fifth International WEIN Symposium is devoted to physics beyond the standard model. This talk is about tau lepton physics, but I begin with the question: do we know how to fin…
