Search for scalar neutrino superpartners in e+μ final states in pp̄ collisions at s=1.96TeV
Physical Review Letters 100:24 (2008)
Abstract:
We report a search for R-parity-violating production and decay of sneutrino particles in the eμ final state with 1.04±0.06fb-1 of data collected with the D0 detector at the Fermilab Tevatron Collider in 2002-2006. Good agreement between the data and the standard model prediction is observed. With no evidence for new physics, we set limits on the R-parity-violating couplings λ311′ and λ312 as a function of the sneutrino mass. © 2008 The American Physical Society.Measurement of Neutrino Oscillations with the MINOS Detectors in the NuMI Beam

Search for resonant tt̄ production in pp̄ collisions at s=1.96TeV
Physical Review Letters 100:23 (2008)
Abstract:
We report on a search for narrow-width particles decaying to a top and antitop quark pair. The data set used in the analysis corresponds to an integrated luminosity of 680pb-1 collected with the Collider Detector at Fermilab in run II. We present 95% confidence level upper limits on the cross section times branching ratio. Assuming a specific top-color-assisted technicolor production model, the leptophobic Z′ with width ΓZ′=0.012MZ′, we exclude the mass range MZ′<725GeV/c2 at the 95% confidence level. © 2008 The American Physical Society.First run II measurement of the W boson mass at the Fermilab Tevatron

Abstract:
We describe a measurement of the W boson mass mW using 200pb-1 of s=1.96TeV pp̄ collision data taken with the CDF II detector. With a sample of 63964 W→eν candidates and 51128 W→μν candidates, we measure mW=[80.413±0.034(stat)±0.034(sys)=80.413±0.048]GeV/c2. This is the single most precise mW measurement to date. When combined with other measured electroweak parameters, this result further constrains the properties of new unobserved particles coupling to W and Z bosons. © 2008 The American Physical Society.First observation of coherent π0 production in neutrino–nucleus interactions with Eν<2 GeV
