Chiral-soliton predictions for exotic baryons
We re-analyze the predictions of chiral-soliton models for the masses and decay widths of baryons in the exotic antidecuplet of flavour SU(3). The calculated ranges of the chiral-soliton moment of inertia and the π-nucleon scattering ΣπN term are used together with the observed baryon octet and decuplet mass splittings to estimate 1430MeV < mΘ+ < 1660MeV and 1790 MeV < mΞ−− < 1970MeV. These are...
متن کامل1/N Expansion for Exotic Baryons
The 1/Nc expansion for exotic baryons is developed, and applied to the masses, meson couplings and decay widths. Masses and widths of the 27 and 35 pentaquark states in the same tower as the 10 ⊃ Θ+ are related by spin-flavor symmetry. The 27 and 35 states can decay within the pentaquark tower, as well as to normal baryons, and so have larger decay widths than the lightest pentaquark Θ. The 1/N...
متن کاملHadronic Aspects of Exotic Baryons
In this talk I look into three different topics, addressing first the possibility that the Θ is a bound state of KπN , exploiting the results of this study to find out the contribution of two meson and one baryon components in the baryon antidecuplet and in the third place I present results on a new resonant exotic baryonic state which appears as dynamically generated by the Weinberg Tomozawa ∆...
متن کاملPentaquark Exotic Baryons in the Skyrme Model
We investigate the pentaquark(P ) exotic baryons as soliton-antiflavored heavy mesons bound states in the limit of infinitely heavy meson mass. Our approach respects the chiral symmetry as well as the heavy quark symmetry. The results reveal a possibility for the loosely bound non-strange P -baryon(s). A pentaquark (P ) baryon [1, 2] is an exotic baryon predicted in quark models, which consists...
متن کاملthe search for the self in becketts theatre: waiting for godot and endgame
this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...
