Abstract:

A measurement of the spin alignment of charged D* mesons produced in continuum e+e-→cc̄ events at √s = 10.5 GeV is presented. This study using 4.72 fb-1 of CLEO II data shows that there is little evidence of any D* spin alignment.

Abstract:

We search for new long-lived particles which decay to Z0 bosons by looking tor Z0→e+e- decays with displaced vertices. We find no evidence for parent particles of the Z0 with long lifetimes in 90 pb-1 of data from the CDF experiment at Fermilab. We set a cross section limit as a function of the lifetime of the parent particle for both a generic Z0 parent and a fourth-generation, charge -1/3 quark that decays into Z0b.
