Search for New Physics with High Mass Tau Pairs in CDF

چکیده
We present the results of a search for new particles decaying to tau pairs, using data corresponding to integrated luminosity 195 pb collected with the CDF detector of the Tevatron. Hypothetical particles, such as and MSSM Higgs boson A can potentially produce such pairs. We discuss the methods of tau identification, and show the signal acceptance versus new particle mass. The low-mass region, dominated by , is used as a control region. No significant excess events over the estimated backgrounds is observed in the high-mass region, and we set upper limits on the cross section times branching ratio as a function of the and A mass.

Search for Neutral MSSM Higgs Bosons Decaying to Tau Pairs
We present the results of a search for inclusive production of neutral MSSM Higgs bosons in pp̄ collisions at 1.96 TeV center of mass energy. The data were collected with the CDF II detector at the Tevatron collider at Fermilab, and correspond to an integrated luminosity of 992 pb−1. The search is performed in the di-τ Higgs decay mode. No significant excess of events above the standard model ba...
متن کاملResults of a Model-independent Global Search for New Physics at Cdf
Data collected in Run II of the Fermilab Tevatron are searched for indications of new electroweak-scale physics. Rather than focusing on particular new physics scenarios, CDF data are analyzed for discrepancies with the Standard Model prediction. A model-independent approach (Vista) considers gross features of the data, and is sensitive to new large crosssection physics. Further sensitivity to ...
متن کاملSearches for Squarks and Gluinos at the Tevatron
We show results on searches for squarks and gluinos performed on up to 2.1 fb−1 of data from proton-antiproton collisions at 1.96 TeV center of mass energy, collected using the CDF and D0 detectors at the Fermilab Tevatron Run II. Events with multiple jets of hadrons and large missing transverse energy in the final state are studied within the framework of minimal supergravity (mSUGRA) and assu...
متن کاملTheoretical Study of the Electroweak Interaction – Present and Future
There have been several important recent developments in precision electroweak tests. These include: the new LEP energy scan during the 1993 run; the first high-precision results on the left-right asymmetry from the SLD Collaboration at SLAC; the probable discovery of the top quark by the CDF Collaboration at Fermilab and the determination of its mass. I will discuss the implications of these a...
متن کاملThe Tau Lepton and the Search for New Elementary Particle
This Fifth International WEIN Symposium is devoted to physics beyond the standard model. This talk is about tau lepton physics, but I begin with the question: do we know how to nd new physics in the world of elementary par-ticles? This question is interwoven with the various tau physics topics. These topics are: searching for unexpected tau decay modes; searching for additional tau decay mechan...
