We report on a search for a dijet resonance in events with only two or three jets and large imbalance in the total event transverse momentum. This search is sensitive to the possible production of a new particle in association with a W or Z boson, where the boson decays leptonically with one or more neutrinos in the final state. We use the full data set collected by the CDF II detector at the Tevatron collider at a proton-antiproton center-of-mass energy of 1.96 TeV. These data correspond to an integrated luminosity of 9.1 fb{̂-1}. We study the invariant mass distribution of the two jets with highest transverse energy. We find good agreement between data and standard model background expectations and measure the combined cross section for WW, WZ, and ZZ production to be 13.8{̂+3.0}_{-2.7} pb. No significant anomalies are observed in the mass spectrum and 95% credibility level upper limits are set on the production rates of a potential new particle in association with a W or Z boson.

Using data corresponding to an integrated luminosity of 79 pb−1, D0 has searched for events containing multiple jets and large missing transverse energy in p{bar p} collisions at √s = 1.8 TeV at the Fermilab Tevatron collider. Observing no significant excess beyond what is expected from the standard model, they set limits on the masses of squarks and gluinos and on the model parameters m0 and m12, in the framework of the minimal low-energy supergravity models of supersymmetry. For tan [beta] = 2 and A0 = 0, with [mu]

A must-have guide for any parent or teacher of a child struggling to learn to read, this essential resource begins by answering the question "What is Dyslexia?" The authors have masterfully selected and distilled the most significant research in the field to provide clear and detailed explanations of the: 1) widely accepted research-based definition of dyslexia; 2) identification and treatment of dyslexia at various stages of development; 3) emotional consequences of reading difficulties; 4) current research on the role of genetics and the brain; 5) essential elements of effective reading instruction; and 6) treatment options for the most severe cases of dyslexia and other reading problems.
