Tau decays beyond the standard model
In a recent paper, 8 semileptonic parameters were defined to specify the most general Lorentz-invariant spin correlation functions for 2-body τ decays. These parameters can be used to search for anomalous Γ L , Γ T polarized-partial widths, for non-CKM-type leptonic CP violation, and for leptonic T FS violation. They can also be used to bound the effective-mass scales A for “new physics” arising from additional Lorentz structures, e.g. from lepton compositeness, tau weak magnetism, weak electricity, or second-class currents. It is emphasized that (i) for these tests “different modes have different merits” and that (ii) the parameters can be measured either by using spin-correlation techniques without polarized beams, or with longitudinally polarized beams.

Calibration and performance of a drift chamber spectrometer
Abstract We describe the calibration of a forward, high-resolution, drift chamber spectrometer used in a series of high energy experiments at Fermilab. We discuss the position-time calibration, the overall performance, and the spatial resolution, obtained under data-taking conditions for two kinds of field-shaping wire geometries.

Proton irradiation effects on 2Gb flash memory
We report total ionizing dose and single event effects on 2 Gb Samsung flash memory devices after exposure to 200 MeV protons to various doses up to 83 krad(Si). We characterize observed failures and single event upsets on 22 devices from two different lots. Devices from both lots are robust to greater than 20 krad(Si) although we see evidence for lot-to-lot variation where only one lot appears robust up to about 50 krad(Si). Single event upsets are observed at a relatively low rate and are consistent with single isolated bit flips within registers that transfer bits to and from the flash memory cells.

Eta gamma Decays of rho0, omega, and phi Mesons
eta..gamma.. decays of rho/sup 0/, ..omega.., and phi are studied. We find GAMMA (phi..-->..eta..gamma..) =55 +- 12 keV. Our data admit two solutions for (rho/sup 0/, ..omega..) ..-->..eta..gamma..: Either GAMMA (rho/sup 0/..-->..eta..gamma..) =50 +- 13 keV, GAMMA (..omega -->..eta..gamma..) =3.0/sup +2//sup .//sup 5//sub -//sub 1//sub .//sub 8/ keV, and the (..omega..,rho) ..-->..eta..gamma.. relative decay phase is near zero; or GAMMA (rho/sup 0/..-->..eta..gamma..) =76 +- 15 keV, GAMMA (..omega -->..eta..gamma..) =29 +- 7 keV, and the decay phase is near 180degree.
