The Intermediate Silicon Layers (ISL) detector is currently being built as part of the CDF II detector upgrade project. The ISL detector will significantly improve tracking in the central region and, ...together with the Silicon Vertex detector, provide stand-alone 3D track information in the forward/backward regions. In this article, we present the quality of the production sensors manufactured by Hamamatsu Photonics, which account for roughly half of the silicon sensors used in the ISL detector.

The Intermediate Silicon Layers Detector is presently being built as part of the CDF upgrades to prepare for the next Tevatron data taking run, scheduled to start in the year 2000. The ISL will be ...located in the radial region between the Silicon Vertex Detector and the Central Outer Tracker. It will add tracking in the forward region and significantly improve tracking in the central region. Together with the SVX II, the ISL forms a standalone, 3D silicon tracker. In this article we present the design of the ISL and the current status of its construction.
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.
