Soft cover. Condición: Good. Gell-Mann, Murray. P. Ramond, and R. Slansky. "Color embeddings, charge assignments, and proton stability" in Reviews of Modern Physics, October 1974, vol 50 no. 4. Original wrappers. The Gell-Mann et al is on pp 721-744 in the issue of pp 721-915. G/VG copy. "Three problems in hypothetical unified theories of electromagnetic, weak, and strong interactions are discussed here. First, the problem of embedding color in any simple gauge group is solved, and a complete classification of theories where the fermion color is restricted to 1c, 3c, and ¯3c of SUc3 is given. Generalizations are also indicated. Second, an unbroken U1 generated by electric charge is embedded into each of the above theories and the charge assignments analyzed. Third, the general problem of stabilizing the proton by a suitable atomic mass number A is studied for the same set of theories. It is always possible to define A if the gauge group is not too small.--abstract.…

Soft cover. Condición: Very Good. FEYNMAN, R.P. and Murray Gell-Mann. "Theory of Fermi Interaction", in "Physical Review", January 1, 1958, volume 109 number 1, pp 193-198, in the issue of pp 1-226.  This is copy removed from a larger bound volume, but with the original wrappers, with a rubber stamp of the National Bureau of Standards.  Very fresh and crisp copy, and otherwise in fine condition. __+__ "Around the same time, Murray Gell-Mann--Feynman's younger colleague and friendly rival at Caltech--arrived at the same conclusion. Rather than see his two star theorists devolve into a messy priority dispute, Caltech's physics department chair, Robert Bacher, wisely suggested that Feynman and Gell-Mann publish an article together. Their paper, titled "Theory of the Fermi Interaction", arrived at "Physical Review" in September 1957, just days before another pair of theorists the University of Rochester's Robert Marshak and his graduate student, E. C. George Sudarshan presented a similar theory at a conference in Italy. (In fact, Marshak and Sudarshan had visited with Gell-Mann in California a few months earlier, while Feynman was vacationing in Brazil.) Feynman often considered this work to be his greatest success: for the first time, he had discovered a genuine law of nature." --Complete Dictionary Scientific Biography, online.…

1st Edition. RARE FIRST EDITION, FIRST ISSUE of the INTRODUCTION OF THE YANG-MILLS QUANTUM MECHANICAL THEORY. Also included in this volume is the paper in which Gell-Mann and Goldberger introduce crossing symmetry. "It is shown that an exact calculation in quantum field theory gives results identical with those obtained by classical methods or else by use of the Dirac equation with an anomalous Pauli moment" (Abstract). Also included is an important paper by Gian Carlo Wick introducing Wick's Theorem, a method of reducing high-order derivatives to a combinatorics problem used extensively in quantum field theory. YANG-MILLS THEORY: The Yang-Mills theory is now the foundation of most of elementary particle theory; it is the mathematical foundation underlying "three of the four fundamental forces of nature that physicists succeeded in unifying in the last half of the 20th century: electromagnetism, the 'weak force' responsible for radioactive decay, and the 'strong force' responsible for holding the nuclei of atoms together" (Gale, World of Mathematics Summary). Yang and Mills proposed a tensor equation that relies on a quantum mechanical property called the 'mass gap.' "The laws of quantum physics stand to the world of elementary particles in the way that Newton's laws of classical mechanics stand to the macroscopic world. Almost half a century ago, Yang and Mills introduced a remarkable new framework to describe elementary particles using structures that also occur in geometry. The successful use of Yang-Mills theory (now widely tested and affirmed) to describe the strong interactions of elementary particles depends on a subtle quantum mechanical property called the "mass gap:" the quantum particles have positive masses, even though the classical waves travel at the speed of light. This property has been discovered by physicists from experiment and confirmed by computer simulations, but it still has not been understood from a theoretical point of view. Progress in establishing the existence of the Yang-Mills theory and a mass gap and will require the introduction of fundamental new ideas both in physics and in mathematics" (Clay Mathematics Institute).
