On the Implications of Discrete Symmetries for the Beta Function of Quantum Hall Systems

C. P. Burgess, C. A. Lutken

We argue that the large discrete symmetry group of quantum Hall systems is insufficient in itself to determine the complete beta function for the scaling of the conductivities, $σ_…

Rho Meson Broadening in Hot and Dense Hadronic Matter

Song Gao, Charles Gale, Christoph Ernst +2

The modification of the width of rho mesons due to in-medium decays and collisions is evaluated. The decay width is calculated from the imaginary part of the one-loop self-energy a…

Neutrons from multiplicity-selected La-La and Nb-Nb collisions at 400A MeV and La-La collisions at 250A MeV

M. M. Htun, R. Madey, W. M. Zhang +19

Triple-differential cross sections for neutrons from high-multiplicity La-La collisions at 250 and 400 MeV per nucleon and Nb-Nb collisions at 400 MeV per nucleon were measured at…

Bilepton Production at Hadron Colliders

B. Dion, T. Gregoire, D. London +2

We examine, as model-independently as possible, the production of bileptons at hadron colliders. When a particular model is necessary or useful, we choose the 3-3-1 model. We consi…

Measurement of the Branching Fractions and Form Factor

J. Bartelt

Using a sample of 3.3 million B-meson decays collected with the CLEO detector at the Cornell Electron Storage Ring, we have studied and $\bar{B}^0 \to D^+ \ellν…

Search for Exclusive Rare Baryonic Decays of Mesons

T. E. Coan

We report the results of a search for the rare baryonic decay modes B -> Lambda Lambdabar, B -> Lambdabar p, B -> Lambdabar p pi, and B -> p pbar using 5.8M BBbar pairs collected w…
