We present new limits on resonant tb production in ppbar collisions at sqrt(s) = 1.96 TeV, using 1.9 fb−1 of data recorded with the CDF II detector at the Fermilab Tevatron. We reconstruct a putative tb mass in events with a lepton, neutrino candidate, and two or three jets, and search for anomalous tb production as modeled by W′ → tb. We set a new limit on a right-handed W′ with standard model-like coupling, excluding any mass below 800 GeV at 95% C.L. For any narrow W′-like state with mass above 800 GeV, the cross-section is found to be less than 0.28 pb at 95% C.L. We also present an exclusion of the W′ coupling strength versus W′ mass.
Written by authors working at the forefront of research, this accessible treatment presents the current status of the field of collider-based particle physics at the highest energies available, as well as recent results and experimental techniques. It is clearly divided into three sections; The first covers the physics -- discussing the various aspects of the Standard Model as well as its extensions, explaining important experimental results and highlighting the expectations from the Large Hadron Collider (LHC). The second is dedicated to the involved technologies and detector concepts, and the third covers the important - but often neglected - topics of the organisation and financing of high-energy physics research. A useful resource for students and researchers from high-energy physics.
Beyond the world of atoms, at scales smaller than the smallest nuclei, a new world comes into view, populated by an array of colorful elementary particles: strange and charmed quarks, muons and neutrinos, gluons and photons, and many others, all interacting in beautifully intricate patterns. Beyond the Nanoworld tells the story of how this new real

The first English translation of essays from one of the twentieth century's most intriguing avant-garde writers Compiled from two volumes of Raymond Queneau's essays (Bâtons, chiffres et lettres and Le Voyage en Grèce), these selections find Queneau at his most playful and at his most serious, eloquently pleading for a certain classicism even as he reveals the roots of his own wildly original oeuvre. Ranging from the funny to the furious, they follow Queneau from modernism to postmodernism by way of countless fascinating detours, including his thoughts on language, literary fashions, myth, politics, poetry, and other writers (Faulkner, Flaubert, Hugo, and Proust). Translator Jordan Stump provides an introduction as well as explanatory notes about key figures and Queneau himself.
