Book Description
New results on the zeta(2.2) are reported. Mark III has analyzed new J/psi data and reconfirmed the zeta(2.2) in radiative J/psi decays to K/sub S/°K/sub S/° and KK−. The significances of the signals are 3.6 and 4.5 standard deviations, the masses, 2.232 +- 007 +- 007 and 2.230 +- 006 +- 014 GeV/c2, and the widths, 0.018/sub -.015//sup +.023/ +- 010 and 0.026/sub -.016//sup +.020/ +- 017 GeV/c2, for the K/sub S/°K/sub S/° and KK− modes, respectively. The branching ratios are BR(J/psi .-->. .gamma.zeta, zeta .-->. K/sub S/°K/sub S/°) = (3.2/sub -1.3//sub +1.6/ +- 0.7) x 10−5 and BR(J/psi .-->. .gamma.zeta, zeta .-->. K+K−) = (4.2/sub -1.4//sup +1.7/ +- 0.8) x 10−5. 14 refs., 9 figs.

Book Description
The Hadron Mass Spectrum covers the proceedings of the Rheinfels Workshop on the Hadron Mass Spectrum, held in St. Goar, Germany on September 3-6, 1990. The book focuses on the processes, methodologies, and reactions involved in hadron spectroscopy. The selection first offers information on strange meson and strangeonium spectroscopy and strangeonium production from LASS. The book also takes a look at the status of strange meson spectroscopy, including status of the spectroscopy, systematics of the level structure, and contributions from LASS. The publication examines the scalar meson enigma and two photon couplings of scalar and tensor mesons. The manuscript also touches on rhoprimes, omegaprimes, and glueballs; meson production mechanisms and selection criteria for cryptoexotic states; and light meson spectroscopy and threshold effects. The selection is a dependable reference for readers interested in hadron mass spectrum.

Book Description
From 5 to 15 August 1984, a group of 79 physicists from 61 laboratories in 26 countries met in Erice for the 22nd Course of the International School of Subnuclear Physics. The countries represented were Austria, Belgium, Brazil, Bulgaria, Canada, People's Republic of China, Denmark, the Federal Republic of Germany, France, Greece, Hungary, Iran, Israel, Italy, Japan, Korea, Malaysia, Mexico, the Netherlands, Pakistan, Poland, Sweden, Switzerland, Turkey, the United Kingdom, the United States of America. The School was sponsored by the Italian Ministry of Public Education (MPI), the Italian Ministry of Scientific and Technologi cal Research (MRST), the Regional Sicilian Government (ERS), and the Weizmann Institute of Science. The programme of the School was devoted to a review of the most significant results in theoretical and experimental research work on the interactions between what we believe today are the point like constituents of the world: quarks and leptons. It should however not be forgotten that many problems are still to be understood: especially in the forefront of the correla tion between quarks and leptons. This game started in 1966 with the proposal for "leptonic quarks" and went on with "preons" and "rishons" just to quote the most famous attempts to unify these two worlds.

Book Description
This meeting on Hadron Spectroscopy and the Confinement Problem took place from June 27 to July 8, 1995. The first four days were at Queen Mary and Westfield College, London and the last six at the University College of Swansea, Wales. The reason for the split sites was a question of accomodating the 54 students and 12 lecturers. However, it was enjoyed by all concerned, providing the opportunity to sample the nightlife of London one week and enjoy the delightful coastal area around Swansea the following week. The meeting immediately preceded the Hadron '95 conference in Manchester. The contents of this volume run roughly parallel to the order of the lectures. Martin Faessler's brief and that of Madjid Boutemeur was to review experimental tech niques as well as physics results. We have tried to review all the areas which are currently active experimentally. This means mostly Light Meson Spectroscopy. However, Simon Capstick gave us a welcome review of Baryon Spectroscopy and the coming CEBAF program. This is an opportunity to thank NATO for their generous financial support, and also the two host institutions for excellent coordination and an enjoyable stay.
