Stop and Sbottom Searches in Run II of the Fermilab Tevatron
We estimate the Tevatron Run II potential for top and bottom squark searches.
We find an impressive reach in several of the possible discovery channels. We
also study some new channels which may arise in non-conventional supersymmetry
models. In each case we rely on a detailed Monte Carlo simulation of the
collider events and the CDF detector performance in Run I.Comment: 30 pages, LaTeX, 10 figure
Czochralski Silicon as a Detector Material for S-LHC Tracker Volumes
4 pages, 6 figures, 12th Vienna Conference on InstrumentationWith an expected ten-fold increase in luminosity in S-LHC, the radiation environment in the tracker volumes will be considerably harsher for silicon-based detectors than the already harsh LHC environment. Since 2006, a group of CMS institutes, using a modified CMS DAQ system, has been exploring the use of Magnetic Czochralski silicon as a detector element for the strip tracker layers in S-LHC experiments. Both p+/n-/n+ and n+/p-/p+ sensors have been characterized, irradiated with proton and neutron sources, assembled into modules, and tested in a CERN beamline. There have been three beam studies to date and results from these suggest that both p+/n-/n+ and n+/p-/p+ Magnetic Czochralski silicon are sufficiently radiation hard for the cm regions of S-LHC tracker volumes. The group has also explored the use of forward biasing for heavily irradiated detectors, and although this mode requires sensor temperatures less than -50\,C, the charge collection efficiency appears to be promising.Peer reviewe
Report of the Topical Group on Top quark physics and heavy flavor production for Snowmass 2021
This report summarizes the work of the Energy Frontier Topical Group on EW
Physics: Heavy flavor and top quark physics (EF03) of the 2021 Community Summer
Study (Snowmass). It aims to highlight the physics potential of top-quark
studies and heavy-flavor production processes (bottom and charm) at the HL-LHC
and possible future hadron and lepton colliders and running scenarios
Tracker Operation and Performance at the Magnet Test and Cosmic Challenge
During summer 2006 a fraction of the CMS silicon strip tracker was operated in a comprehensive slice test called the Magnet Test and Cosmic Challenge (MTCC). At the MTCC, cosmic rays detected in the muon chambers were used to trigger the readout of all CMS sub-detectors in the general data acquisition system and in the presence of the 4 T magnetic field produced by the CMS superconducting solenoid. This document describes the operation of the Tracker hardware and software prior, during and after data taking. The performance of the detector as resulting from the MTCC data analysis is also presented
