This is an updated version of the book published in 1985. QCD-motivated, it gives a detailed description of hadron structure and soft interactions in the additive quark model, where hadrons are regarded as composite systems of dressed quarks.In the past decade it has become clear that nonperturbative QCD, responsible for soft hadronic processes, may differ rather drastically from perturbative QCD. The understanding of nonperturbative QCD requires a detailed investigation of the experiments and the theoretical approaches. Bearing this in mind, the book has been rewritten paying special attention to the interplay of soft hadronic collisions and the quark model. It is at the crossroads of these...
This book is devoted to the investigation of the strongly interacting hadrons — to a quark model operating with effective color particles, constituent quarks, massive effective gluons and diquarks. The study of strong interactions based on effective constituent particles requires a solid ground of experimental data, which we now have at our disposal with the serious progress made in the investigation of hadrons, especially meson states.The present understanding of QCD applied to strong interactions can be distorted by prejudices. Therefore, the way followed by the quark model is to rely on the experiment and to restore the effective Hamiltonian on the basis of QCD on the one hand, and, on ...

Vladimir Naumovich Gribov was one of the most outstanding theorists, a key figure in the creation of the modern elementary particle physics. His many discoveries are famous and well accepted by the physics community (Gribov-Regge theory of high energy hadron interactions, Gribov vacuum pole ? Pomeron, Reggeon field theory, parton evolution equations, neutrino oscillations, Gribov copies in non-Abelian gauge field theories, etc.); Some of his ideas look unacceptable and strange at the first glance. Even at the second glance.Nowadays, under the weight of new theoretical developments and experimental results, his ideas are receiving the recognition they deserve. The Gribov Memorial Workshop, organized on his 75th birthday in Budapest, Hungary in 2005, clearly demonstrated the wealth and fertilization force of his ideas. Close colleagues, younger followers, world experts of the quark-hadron world have gathered together to display new angles of the Gribov heritage. And to remember the personality of a great man.This book collects the talks presented at, and contributed to, the Gribov-75 Memorial Workshop.
This book gives a comprehensive account of the development and present status of the field of soft (i.e. non-perturbative) phenomena encountered in the production of (multi-) hadronic final states by the collision of various types of particles at high energies. Phenomenological models used to describe the data are in general inspired by Quantum Chromo Dynamics (QCD) and the book repeatedly crosses the border — if at all existent — between soft (non-perturbative) and hard (perturbative) QCD.
A series of new and relevant experimental results are here presented to the community for the first time. In particular, we refer to the measurement of the neutron spin structure functions by the SLAC (E142) and CERN (SMC) collaborations; the first results from MAMI on experiments with tagged photons (A1 collaboration), on electroproduction of multi-hadron final states (A2 collaboration) and the neutron form factor (A3 collaboration); the experiments on strangeness photoproduction at ELSA; the polarization experiments at Bates on the neutron form factor and nuclear response functions and the photon and electron scattering data obtained by the Genova-Frascati Jet Target collaboration.Focused on the study of spin observables and exclusive processes at high momenta, the following sessions were held: The Neutron Form Factors; Spin Structure Functions; Exclusive Processes at High υ and Q2. Deep Inelastic Scattering; Spin Observables; One- and Two-Nucleon Knockout at Low and Intermediate Energies; Excitation of Baryons Resonances and Strangeness.
Robotics, Second Edition is an essential addition to the toolbox of any engineer or hobbyist involved in the design of any type of robot or automated mechanical system. It is the only book available that takes the reader through a step-by step design process in this rapidly advancing specialty area of machine design. This book provides the professional engineer and student with important and detailed methods and examples of how to design the mechanical parts of robots and automated systems. Most robotics and automation books today emphasis the electrical and control aspects of design without any practical coverage of how to design and build the components, the machine or the system. The auth...
The necessity of describing three-nucleon and three-quark systems have led to a constant interest in the problem of three particles. The question of including relativistic effects appeared together with the consideration of the decay amplitude in the framework of the dispersion technique. The relativistic dispersion description of amplitudes always takes into account processes connected with the investigated reaction by the unitarity condition or by virtual transitions; in the case of three-particle processes they are, as a rule, those where other many-particle states and resonances are produced. The description of these interconnected reactions and ways of handling them is the main subject of the book.
