29 Jul 2004 | | Journal: | Int.J.Mod.Phys. A20 (2005) 693-695 | | Subject: | hep-ph | | Abstract: | The scalar-isoscalar, scalar-isotensor and vector-isovector pi-pi amplitudes are fitted simultaneously to experimental data and to Roy’s equations. The resulting amplitudes are compared with those fitted only to experimental data. No additional constraints for the pi-pi threshold behaviour of the amplitudes are imposed. Threshold parameters are calculated for the amplitudes in the three waves. Spectrum of scalar mesons below 1.8 GeV is found from the analysis of the analytical structure of the fitted amplitudes. | | Source: | arXiv, hep-ph/0407338 | | Services: | Forum | Review | PDF | Favorites | |
