Search for excited and exotic muons in the μy decay channel in pp - collisions at s=1.96 TeV
Physical Review Letters 97:19 (2006)
Abstract:
We search for excited and exotic muon states * using an integrated luminosity of 371pb-1 of pp collision data at s=1.96TeV. We search for associated production of * followed by the decay *. We compare the data to model predictions as a function of the mass of the excited muon M *, the compositeness energy scale , and the gauge coupling factor f. No signal above the standard model expectation is observed. We exclude 107Search for higgs bosons decaying to bb̄ and produced in association with W bosons in pp̄ collisions at s=1.96TeV

Abstract:
We present a search for Higgs bosons decaying into bb̄ and produced in association with W bosons in pp̄ collisions at s=1.96TeV. This search uses 320pb-1 of the data set accumulated by the upgraded Collider Detector at Fermilab. Events are selected that have a high-transverse momentum electron or muon, missing transverse energy, and two jets, at least one of which is consistent with the hadronization of a b quark. Both the number of events and the dijet mass distribution are consistent with standard model background expectations, and we set 95% confidence level upper limits on the production cross section times branching ratio for the Higgs boson or any new particle with similar decay kinematics. These upper limits range from 10 pb for mH=110GeV/c2 to 3 pb for mH=150GeV/c2. © 2006 The American Physical Society.Search for resonant second generation slepton production at the Fermilab tevatron

Abstract:
We present a search for supersymmetry in the R-parity violating resonant production and decay of smuons and muon sneutrinos in the channels, 2,3,40. We analyzed 0.38fb-1 of integrated luminosity collected between April 2002 and August 2004 with the D0 detector at the Fermilab Tevatron Collider. The observed number of events is in agreement with the standard model expectation, and we calculate 95% C.L. limits on the slepton production cross section times branching fraction to gaugino plus muon, as a function of slepton and gaugino masses. In the framework of minimal supergravity, we set limits on the coupling parameter, extending significantly previous results obtained in Run I of the Tevatron and at the CERN LEP collider. © 2006 The American Physical Society.Search for scalar bottom quarks from gluino decays in p̄p collisions at s=1.96TeV
