چکیده

We present a search for new physics in events with two high pT leptons of the same electric charge, using data with an integrated luminosity of 6.1 fb(-1). The observed data are consistent with standard model predictions. We set 95% C.L. lower limits on the mass of doubly charged scalars decaying to like-sign dileptons, m(H±±) > 190-245 GeV/c(2), assuming 100% BR to ee, μμ or eμ.

Study of a Like-Sign Dilepton Search for Chargino-Neutralino Production at CDF

We propose a like-sign dilepton search for chargino-neutralino production in p p collisions at p s = 1:8 TeV, which complements the previously published trilepton search by the CDF detector using Fermilab Run I data. Monte Carlo predictions for the signal and background e ciencies indicate a signi cant increase in sensitivity to chargino-neutralino production compared to the traditional trilept...

A Search for Neutral Heavy Vector Gauge

Figure 1: Distribution of dilepton events as a function of invariant mass in 110 pb of data taken at CDF. In this paper we describe a direct search for the Z ′ in its dielectron and dimuon decay modes at CDF. 4 The calorimeters, the Central Tracking Chamber (CTC) and the Muon chambers are the principal detector components used for this search. 5 Data are collected with a multi-level trigger. Th...

Search for lepton cascades in like-sign dilepton events with jets at CDF with 6.1 fb−1 using simplified models

We present a search for cascade decays of new particles leading to leptons and invisible particles, typical of supersymmetric decays or universal extra dimensions. We analyze events with two leptons of the same electric charge using data with an integrated luminosity of 6.1 fb−1. The observed data are consistent with standard model predictions, and we set cross-section upper limits on productio...

Results 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 ...

A quasi-model-independent search for new electroweak scale physics

These proceedings describe Sleuth, a quasi-model-independent search strategy targeting new electroweak scale physics, and its application to 927 pb of CDF II data. Exclusive final states are analyzed for an excess of data beyond the Standard Model prediction at large summed scalar transverse momentum ( P pT ). This analysis of highP pT data represents one of the most encompassing searches so fa...

Like-Sign Dileptons at the Fermilab Tevatron Revisited in the Light of the HERA High-Q Anomaly

We re-examine like-sign dilepton signals at the Fermilab Tevatron assuming that the excess high-Q events recently seen at HERA are due to the production and decay of squarks of R-parity-violating supersymmetry. For gluinos in the mass range of 200–350 GeV, the like-sign dilepton signal can help to make the crucial distinction between the most favoured squark explanation and other proposed solut...
