• Sommario/riassunto: This book describes the underlying ideas and modern developments of Regge theory, confronting the theory with quantum chromodynamics ; and a huge variety of experimental data. It covers forty years of research and provides a unique insight into the theory and its phenomenological development. The authors review experiments that suggest the existence of a soft pomeron, and give a detailed discussion of attempts at describing this through nonperturbative quantum chromodynamics. They suggest that a second, hard pomeron is responsible for the dramatic rise in energy observed in deep inelastic lepton scattering. The two-pomeron hypothesis is applied to a variety of interactions and is compared and contrasted with perturbative quantum chromodynamics, as well as with the dipole approach. This book will provide a valuable reference for experimental particle physicists all over the world. It is also suitable for graduate courses in particle physics, high-energy scattering, QCD and the standard model.

• Sommario/riassunto: How Race Is Made in America examines Mexican Americans-from 1924, when American law drastically reduced immigration into the United States, to 1965, when many "as were abolished-to understand how broad themes of race and citizenship are constructed. These years shaped the emergence of what Natalia Molina describes as an immigration regime, which defined the racial categories that continue to influence perceptions in the United States about Mexican Americans, race, and ethnicity. Molina demonstrates that despite the multiplicity of influences that help shape our concept of race, common themes prevail. Examining legal, political, social, and cultural sources related to immigration, she advances the theory that our understanding of race is socially constructed in relational ways-that is, in correspondence to other groups. Molina introduces and explains her central theory, racial scripts, which highlights the ways in which the lives of racialized groups are linked across time and space and thereby affect one another. How Race Is Made in America also shows that these racial scripts are easily adopted and adapted to apply to different racial groups.
