Search for new physics in photon-lepton events in pp虅 collisions at 鈭歴 = 1.8 TeV
Physical Review Letters 89:4 (2002)
Abstract:
An a priori search for inclusive photon + lepton production was made. It was found that subsamples of this data set agree well with their standard model (SM) prediction, with the possible exception of 纬鈩撯垊T.The high-energy gamma-ray fluence and energy spectrum of GRB 970417a from observations with Milagrito

Improved W boson mass measurement with the D脴 detector
Physical Review D Particles Fields Gravitation and Cosmology 66:1 II (2002) 120011-1200118
Abstract:
We have measured the W boson mass using the D脴 detector and a data sample of 82 pb-1 from the Fermilab Tevatron collider. This measurement uses W鈫抏谓 decays, where the electron is close to a boundary of a central electromagnetic calorimeter module. Such "edge" electrons have not been used in any previous D脴 analysis, and represent a 14% increase in the W boson sample size. For these electrons, new response and resolution parameters are determined, and revised backgrounds and underlying event energy flow measurements are made. When the current measurement is combined with previous D脴 W boson mass measurements, we obtain MDirect evidence for neutrino flavor transformation from neutral-current interactions in the Sudbury Neutrino Observatory
