We have implemented triggers for hadronically decaying tau leptons within a framework of the CDF Run 2 trigger system. We describe the triggers, along with their physics motivations, and report on ...their initial performance.

The
Intermediate Silicon Layers detector (ISL) is a large radius silicon tracker, installed in the CDF detector for the RUN II of the Tevatron Collider. With almost 4
m
2 of double-sided silicon ...sensors and 300,000 electronic channels it represents the biggest system of this kind ever built. The construction and installation phases, the performed quality assurance tests as well as the problems encountered are reviewed.
RUN II of the Tevatron officially started on March 1st, 2001. Although the CDF silicon system is still being commissioned, results on the performance of the ISL detector obtained using the first data are presented.

The Intermediate Silicon Layers (ISL) detector is part of the CDF upgrade for Run II. The ISL is a large radius (20–28
cm) double-side silicon tracker with a total active area of

The authors present a new search for H{sup 0}V production, where H{sup 0} is a scalar Higgs boson decaying into b{bar b} with branching ratio {beta}, and V is a Z{sup 0} boson decaying into e{sup ...+}e{sup -}, {mu}{sup +}{mu}{sup -}, or {nu}{bar {nu}}. This search is then combined with previous searches for H{sup 0}V where V is a W{sup {+-}} boson or a hadronically decaying Z{sup 0}. The data sample consists of 106 {+-} 4 pb{sup -1} or p{bar p} collisions at {radical}s = 1.8 TeV accumulated by the Collider Detector at Fermilab. Observing no evidence of a signal, they set 95% Bayesian credibility level upper limits on {sigma}(p{bar p} {yields} H{sup 0}V) x {beta}. For H{sup 0} masses of 90, 110 and 130 GeV/c{sup 2}, the limits are 7.8, 7.2, and 6.6 pb respectively.
