Download or read book A Dynamical Picture of Hadron hadron Collisions with the String parton Model written by and published by . This book was released on 1991 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: We introduce a dynamical model for the description of hadron-hadron collisions at relativistic energies. The model is based on classical Nambu-Goto strings. The string motion is performed in unrestricted four-dimensional space-time. The string endpoints are interpreted as partons which carry energy and momentum. We study ee−, e -- p, and p -- p collisions at various center of mass energies. The three basic features of our model are as follows. An ensemble of strings with different endpoint dynamics is used to approximately reproduce the valence quark structure functions. We introduce an adiabatic hadronization mechanism for string breakup via q{bar q} pair production. The interaction between strings is formulated in terms of a quark-quark scattering amplitude and exchange. This model will be used to describe relativistic heavy-ion collisions in future work. 28 refs., 3 figs., 1 tab.

Download or read book String parton Model Description of Relativistic Heavy ion Collisions written by and published by . This book was released on 1993 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Various models have been developed to address the ordinary hadronic physics that occurs in relativistic heavy-ion collisions. These include string-based fragmentation models such as the LUND model, and its extensions in FRITIOF, which assume that excited hadrons behave as a chain of color dipoles that move like one-dimensional relativistic strings. Interactions are introduced via multiple small momentum exchanges between the color dipoles of two overlapping strings. Other nondynamical models are the dual-parton model, in which the strings are formed by soft gluon exchange between the valence partons of the colliding hadrons. The quark-gluon string model, also based on the dual parton model, has been developed to study soft parton collisions, and includes rescattering. The strings in the above models are in fact one-dimensional constructions in momentum space, and string evolution is carried out in this space. We have developed a real-time dynamical model for studying the inclusive properties of hadronic collisions in three-dimensions. The model is based on the Nambu-Goto string description of hadrons supplemented by extensions to incorporate the basic features of the parton model, together with a hadronization mechanism. The advantage of having a fully dynamical model is the possibility to explore the detailed time evolution of the hadronic matter. Furthermore, since the model is fully three dimensional, all of the transverse degrees of freedom are available to the evolving system. The model has been successfully applied to the study of high-energy ee−, pp, [mu]p, and [mu]A collisions. These calculations have been used to fix all of the parameters present in the model. For all of the calculations presented here, the model parameters have been held fixed at their predetermined values.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The parton picture of color separation of dual string and its subsequent breakup is used to motivate the DTU-parton model for high energy small p/sub T/ multiparticle productions in hadron-hadron and hadron-nucleus collisions. A brief survey on phenomenological applications of the model: such as the inclusive spectra for various hh processes and central plateau heights predicted, hA inclusive spectra and the approximate anti v-universalities is presented.

This book was released on 1991-01-30 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main theme of this workshop, the fourth meeting in the LESIP series, is correlations and Fluctuations in strong interaction processes. While the emphasis was on Bose-Einstein correlations between identical particles, other kinds of correlations (between non-identical particles, multiplicity distributions, transverse energy distributions, inelasticity distributions etc.) were addressed. The recent developments in fractal dynamics, intermittency, deterministic chaos and information entropy and their roles in high energy physics also was addressed. Finally, transverse energy distributions and inelasticity distributions, insofar as they impart information about thermalization of the energy available for hadronization, was discussed. These issues are of relevance for the current searches for Quark-Gluon-Plasma. The goal of the workshop is to provide a forum for the presentation of new experimental results.

Book excerpt: This volume comprises select peer-reviewed papers from the Indo-French Workshop on Multifragmentation, Collective Flow, and Sub-Threshold Particle Production in Heavy-Ion Reactions held at the Department of Physics, Panjab University, Chandigarh, India in February, 2019. The contents highlight latest research trends in intermediate energy nuclear physics and emphasize on the various reaction mechanisms which take place in heavy-ion collisions. The chapters contribute to the understanding of interactions that govern the dynamics at sub-nucleonic level. The book includes contributions from global experts hailing from major research facilities of nuclear physics, and provides a good balance between experimental and theoretical model based studies. Given the range of topics covered, this book can be a useful reference for students and researchers interested in the field of heavy-ion reactions.

Download or read book Multiple Parton Interactions at the LHC written by Paolo Bartalini and published by World Scientific Publishing. This book was released on 2018-11-08 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many high-energy collider experiments (including the current Large Hadron Collider at CERN) involve the collision of hadrons. Hadrons are composite particles consisting of partons (quarks and gluons), and this means that in any hadron–hadron collision there will typically be multiple collisions of the constituents — i.e. multiple parton interactions (MPI). Understanding the nature of the MPI is important in terms of searching for new physics in the products of the scatters, and also in its own right to gain a greater understanding of hadron structure. This book aims at providing a pedagogical introduction and a comprehensive review of different research lines linked by an involvement of MPI phenomena. It is written by pioneers as well as young leading scientists, and reviews both experimental findings and theoretical developments, discussing also the remaining open issues.
