Searches for non-standard-model higgs bosons at the tevatron

DIS 2008 - Proceedings of the 16th International Workshop on Deep-Inelastic Scattering and Related Topics (2008)

Abstract:

The Standard Model of particle physics has a number of asymmetries suggestive of a more fundamental theory, where the symmetries are restored. If the symmetry breaking scale is the electroweak scale, new Higgs bosons beyond that of the Standard Model could be observed at the Tevatron. Recent Tevatron searches have set the most stringent limits on new Higgs bosons in a variety of models.

Summary of the electroweak and beyond the standard model working group

DIS 2008 - Proceedings of the 16th International Workshop on Deep-Inelastic Scattering and Related Topics (2008)

Authors:

C Hays, M Krämer, DM South, AFZ Arnecki

Abstract:

A wide array of deep-inelastic-scattering and hadron collider experiments have tested the predictions of the electroweak theory and measured its parameters, while also searching for new particles and processes. We summarise recent measurements and searches that probe the Standard Model to unprecedented precision.

Supersymmetry searches at the tevatron

Aip Conference Proceedings 1078 (2008) 67-72

Abstract:

Supersymmetry predicts a range of new phenomena with a variety of experimental signatures. Searches for supersymmetry at the Fermilab Tevatron accelerator fall into three broad categories: generic sparticle searches; specialized searches for sparticles with unusual properties; and model-independent searches probing for discrepancies between the data and the standard model. Searches performed by the CDF and D0 experiments with up to 2 fb-1 of √ s = 1.96 TeVpp data have yet to turn up any evidence for supersymmetry. © 2008 American Institute of Physics.

Abstract:

The SemiConductor Tracker (SCT) data acquisition (DAQ) system will calibrate, configure, and control the approximately six million front-end channels of the ATLAS silicon strip detector. It will provide a synchronized bunch-crossing clock to the front-end modules, communicate first-level triggers to the front-end chips, and transfer information about hit strips to the ATLAS high-level trigger system. The system has been used extensively for calibration and quality assurance during SCT barrel and endcap assembly and for performance confirmation tests after transport of the barrels and endcaps to CERN. Operating in data-taking mode, the DAQ has recorded nearly twenty million synchronously-triggered events during commissioning tests including almost a million cosmic ray triggered events. In this paper we describe the components of the data acquisition system, discuss its operation in calibration and data-taking modes and present some detector performance results from these tests. © 2007 IOP Publishing Ltd and SISSA.
