8 Jul 2004 | | Subject: | hep-ph | | Affiliation: | BLTP, JINR, Dubna), J.Wambach (IKP TU Darmstadt and GSI, Darmstadt), A. Vdovin (BLTP, JINR, Dubna), and Z. Aouissat (IKP TU Darmstadt | | Abstract: | An extended Holstein-Primakoff mapping which incorporates both single- and double boson mappings is used in the context of O(N+1) anharmonic oscillator with the global symmetry broken down to O(N) to study the next-to-leading order of the 1/N expansion. It is shown that the Goldstone theorem is obeyed to that order and that the Ward identity is satisfied. | | Source: | arXiv, hep-ph/0407096 | | Services: | Forum | Review | PDF | Favorites | |
