The Strangeness Magnetic Moment of the Proton in the Chiral Quark Model
The Strangeness Magnetic Moment of the Proton in the Chiral Quark Model L. Hannelius, D.O. Riska Department of Physics, University of Helsinki, 00014 Finland and L. Ya. Glozman Institute for Theoretical Physics, University of Graz, A-8019 Graz, Austria Abstract The strangeness magnetic moment of the proton is shown to be small in the chiral quark model. The dominant loop contribution is due to kaons. The K∗ loop contributions are proportional to the difference between the strange and light constituent quark masses or −2 mK∗ and therefore small. The loop fluctuations that involve radiative transitions between K∗ mesons and kaons are small, when the cut-off scale in the loops is taken to be close to the chiral symmetry restoration scale. The net loop amplitude contribution to the strangeness magnetic moment of the proton is about −0.05, which falls within the uncertainty range of arXiv:hep-ph/9908393v2 24 Aug 1999 the experimental value. 0 1. Introduction The recent finding by the SAMPLE collaboration that the strangeness magnetic moment s 2 2 of the proton is small, and possibly even positive [1] (GM (Q = 0.1 GeV )=0.23 ± 0.37) was unexpected in view of the fact that the bulk of the many theoretical predictions for this quantity are negative, and outside of the experimental uncertainty range (summaries are given e.g. in refs. [2, 3, 4]). A recent lattice calculation gives −0.36 ± 0.20 for this quantity [5], thus reaffirming the typical theoretical expectation, while remaining outside of the uncertainty range of the empirical value. -
An Introduction to Morphos
An Introduction to MorphOS Updated to include features to version 1.4.5 May 14, 2005 MorphOS 1.4 This presentation gives an overview of MorphOS and the features that are present in the MorphOS 1.4 shipping product. For a fully comprehensive list please see the "Full Features list" which can be found at: www.PegasosPPC.com Why MorphOS? Modern Operating Systems are powerful, flexible and stable tools. For the most part, if you know how to look after them, they do their job reasonably well. But, they are just tools to do a job. They've lost their spark, they're boring. A long time ago computers were fun, it is this background that MorphOS came from and this is what MorphOS is for, making computers fun again. What is MorphOS? MorphOS is a fully featured desktop Operating System for PowerPC CPUs. It is small, highly responsive and has very low hardware requirements. The overall structure of MorphOS is based on a new modern kernel called Quark and a structure divided into a series of "boxes". This system allows different OS APIs to be used along side one another but isolates them so one cannot compromise the other. To make sure there is plenty of software to begin with the majority of development to date has been based on the A- BOX. In the future the more advanced Q-Box shall be added. Compatibility The A-Box is an entire PowerPC native OS layer which includes source and binary compatibility with software for the Commodore A500 / A1200 etc. -

This calculation parton momentum becomes soft. In order to illustrate better what is going on, of Feynman diagrams would be a purely academic exercise if we did not use certain I introduce a theoretical tool, null-plane coordinates. Using this tool, I sketch general features of the theory that allow the Feynman diagrams to be related to a space-time picture of the singularities that we find in momentum space. -
Introduction to Storage and Software Systems for Data Analysis
INTRODUCTION TO STORAGE AND SOFTWARE SYSTEMS FOR DATA ANALYSIS Bob Jacobsen University of California, Berkeley, USA Abstract The Storage and Software Systems for Data Analysis track discusses how HEP physics data is taken, processed and analyzed, with emphasis on the problems that data size and CPU needs pose for people trying to do experimental physics. The role of software engineering is discussed in the context of building large, robust systems that must at the same time be accessible to physicists. We include some examples of existing systems for physics analysis, and raise some issues to consider when evaluating them. This lecture is the introduction to those topics. 1. INTRODUCTION Many modern high-energy physics (HEP) experiments are done by collaborations of hundreds of people. Together, these groups construct and operate complex detectors, recording billions of events and terabytes of data, all toward the goal of “doing physics”. In this note, we provide an introduction to how we currently do this, and raise a number of issues to be considered when thinking about the new systems that are now being built. 2. SCALE OF THE EXPERIMENTS BaBar, CDF and D0 are examples of the large experiments now taking or about to take data in a collider environment. The collaborations that have built these experiments contain 300 to 600 members with varying levels of activity. Almost everybody is considered “familiar” with using computing to do their work, but only a small fraction of the collaboration can be considered as computing professionals. Some of these can even be considered world-class experts in large scale computing. -

ARVTEUX Laboratoire National Saturne IN2P3-CNRS &. DSM-CEA, CESaclay F-91191 Gif-sur-Yvette Cedex, France ABSTRACT 1. Introduction This review concerns the facilities which use the lepton probe to learn about nuclear physics. Since this Conference is attended by a large audience coming from diverse horizons, a few definitions may help to explain what I am going to talk about. 1.1. Leptons versus hadrons The particle physics world is divided in leptons and hadrons. Leptons are truly fundamental particles which are point-like (their dimension cannot be measured) and which interact with matter through two well-known forces : the electromagnetic interaction and the weak interaction which have been regrouped in the 70's in the single electroweak interaction following the theoretical insight of S. Weinberg (Nobel prize in 1979) and the experimental discoveries of the Z° and W±- bosons at CERN by C. Rubbia and Collaborators (Nobel prize in 1984). The leptons comprise 3 families : electrons (e), muons (jt) and tau (r) and their corresponding neutrinos : ve, and vr . Nuclear physics can make use of electrons and muons but since muons are produced at large energy accelerators, they more or less belong to the particle world although they can also be used to study solid state physics. -
Second Order Twist Contributions to the Balitsky-Kovchegov Equation at Small-X: Deterministic and Stochastic Pictures
Second Order Twist Contributions to the Balitsky-Kovchegov Equation at small-x: Deterministic and Stochastic Pictures S. K.

This work is done in the high NC limit in the Bjorken picture. I show that the correction to the second twist terms of the stochastic picture suggest additional importance of the second twist correction in the stochastic model as compared to the deterministic model.

Phenomenological Review on Quark–Gluon Plasma: Concepts Vs
Review Phenomenological Review on Quark–Gluon Plasma: Concepts vs. Observations Roman Pasechnik 1,* and Michal Šumbera 2 1 Department of Astronomy and Theoretical Physics, Lund University, SE-223 62 Lund, Sweden 2 Nuclear Physics Institute ASCR 250 68 Rez/Prague,ˇ Czech Republic; [email protected] * Correspondence: [email protected] Abstract: In this review, we present an up-to-date phenomenological summary of research developments in the physics of the Quark–Gluon Plasma (QGP). A short historical perspective and theoretical motivation for this rapidly developing field of contemporary particle physics is provided. In addition, we introduce and discuss the role of the quantum chromodynamics (QCD) ground state, non-perturbative and lattice QCD results on the QGP properties, as well as the transport models used to make a connection between theory and experiment. The experimental part presents the selected results on bulk observables, hard and penetrating probes obtained in the ultra-relativistic heavy-ion experiments carried out at the Brookhaven National Laboratory Relativistic Heavy Ion Collider (BNL RHIC) and CERN Super Proton Synchrotron (SPS) and Large Hadron Collider (LHC) accelerators. We also give a brief overview of new developments related to the ongoing searches of the QCD critical point and to the collectivity in small (p + p and p + A) systems. Keywords: extreme states of matter; heavy ion collisions; QCD critical point; quark–gluon plasma; saturation phenomena; QCD vacuum PACS: 25.75.-q, 12.38.Mh, 25.75.Nq, 21.65.Qr 1. Introduction Quark–gluon plasma (QGP) is a new state of nuclear matter existing at extremely high temperatures and densities when composite states called hadrons (protons, neutrons, pions, etc.) lose their identity and dissolve into a soup of their constituents—quarks and gluons.
