Axion Radiation from Strings

C. Hagmann, S. Chang, P. Sikivie

This paper revisits the problem of the string decay contribution to the axion cosmological energy density. We show that this contribution is proportional to the average relative in…

Search for CP Violation in , and

G. Bonvicini, CLEO Collaboration

We have searched for CP-violating asymmetries in neutral charm meson decays in 13.7 fb^-1 of e^+e^- collision data at sqrt{s} = 10.6 GeV with the CLEO detector. The measured asymme…

Phase transition in a magnetic field in V2-yO3 (y=0 and 0.04)

Wei Bao, A H Lacerda, J D Thompson +2

The effect of a magnetic field on the two long-range-ordered magnetic phases, the collinear insulating antiferromagnetic (AFI) and the incommensurate metallic transverse spin densi…

Measurement of the cross-section and forward-backward charge asymmetry for the b and c-quark in e+e- annihilation with inclusive muons at sqrt(s) = 58 GeV

Y. Inoue

We have studied inclusive muon events using all the data collected by the TOPAZ detector at sqrt(s)=58 GeV with an integrated luminosity of 273pb-1. From 1328 inclusive muon events…

First Measurement of the Ratio B(t-->Wb)/B(t-->Wq) and Associated Limit on the CKM Element Vtb

CDF Collaboration

We present the first measurement of the ratio of branching fraction R= B(t-->wb)/B(t-->Wq) from ppbar collisions at sqrt(s)=1.8 TeV. The data set corresponds to 109 pb-1 of data re…

A Rigorous Real Time Feynman Path Integral

Ken Loo

Using improper Riemann integrals, we will formulate a rigorous version of the real-time, time-sliced Feynman path integral for the transition probability amplitude. We will d…
