AbstractAbstract
[en] The authors extend their earlier calculations of baryon properties in a hybrid quark model based on the Gell-Mann-Levy linear sigma model. They have avoided the projection problems associated with the standard hedgehog ansatz by solving the model using a Fock-space configuration which explicitly incorporates the correct isospin and angular momentum couplings in every component. This Fock-space configuration has components involving three quarks and various numbers of quantal pions. They minimize the ground-state expectation value of their Hamiltonian to obtain the equations of motion which they solve self-consistently. They calculate the canonical set of nucleon observables and compare with previous work

AbstractAbstract
[en] We present experimental results from the BaBar experiment on charm baryon spectroscopy and production studies, including studies of excited cascades produced in charm baryon decays. We review the discovery of new decay modes of known states and searches for predicted states.

AbstractAbstract
[en] The series of workshops on New Partial-Wave Analysis Tools for Next-Generation Hadron Spectroscopy Experiments was initiated with the ATHOS 2012 meeting, which took place in Camogli, Italy, June 20-22, 2012. It was followed by ATHOS 2013 in Kloster Seeon near Munich, Germany, May 21-24, 2013. The third, ATHOS3, meeting is planned for April 13-17, 2015 at The George Washington University Virginia Science and Technology Campus, USA. The workshops focus on the development of amplitude analysis tools for meson and baryon spectroscopy, and complement other programs in hadron spectroscopy organized in the recent past including the INT-JLab Workshop on Hadron Spectroscopy in Seattle in 2009, the International Workshop on Amplitude Analysis in Hadron Spectroscopy at the ECT*-Trento in 2011, the School on Amplitude Analysis in Modern Physics in Bad Honnef in 2011, the Jefferson Lab Advanced Study Institute Summer School in 2012, and the School on Concepts of Modern Amplitude Analysis Techniques in Flecken-Zechlin near Berlin in September 2013. The aim of this document is to summarize the discussions that took place at the ATHOS 2012 and ATHOS 2013 meetings. We do not attempt a comprehensive review of the field of amplitude analysis, but offer a collection of thoughts that we hope may lay the ground for such a document

AbstractAbstract
[en] One of the main problems in baryon spectroscopy is the presence of many so-called "missing resonances". A possible solution to this problem is to describe two correlated quarks inside the baryons by means of the diquark effective degree of freedom. Three different quark-diquark models are developed and compared. Some theoretical predictions are given and compared with the available experimental data. (author)

AbstractAbstract
[en] Hidden-color basis states of multiquark systems are expressed in terms of states involving color-singlet hadrons. The size of various nucleon form factors is used to separate the interior perturbative region of quarks from the exterior nonperturbative region of hadrons. The distinction between the baryon interior and its exterior appears to be relevant in baryon spectroscopy and in nuclear forces. 26 refs.; 1 figure
