St Petersburg, Rusia). I would very much like to thank the organizers for their warm hospitality, particularly Sergey Afonin, Sasha Andrianov and Domenec Espriu, for inviting me to give this review and nice organization of the workshop.This work is supported in part by the Spanish Research contract , FPA2011-27853-C02-02 and the EU FP7 HadronPhysics3 project. | |
| dc.description.abstract | This is a brief account of the recent developments on the determination of the mass and widths of the much debated scalar mesons, paying particular attention to the causes of major revision of the σ or f_0(500) meson in the last edition of the Review of Particle Physics, which has finally acknowledged that the situation concerning the mass and width of this controversial state has been settled, although this was already well-known to scalar meson practitioners for about a decade. I will briefly comment on the dispersive approach, followed by several groups, which seems to have been the most decisive in support of the existence and precise determinations of scalar meson properties. | |
