On the pentaquark candidates and within the soliton picture of baryons
N. N. Scoccola, D. O. Riska, Mannque Rho
Using the bound state version of the topological soliton model for the baryons we show that the existence of a bound (or quasi-bound) -soliton state leads to the possibilit…
The particle as a canonically quantized multiskyrmion
A. Acus, E. Norvaisas, D. O. Riska
The rational map approximation to the solution to the SU(2) Skyrme model with baryon number B=4 is canonically quantized. The quantization procedure leads to anomalous breaking of…
Baryon Magnetic Moments in Relativistic Quark Models
B. Julia-Diaz, D. O. Riska
It is shown that the phenomenological description of the baryon magnetic moments in the quark model carries over to the Poincaré covariant extension of the model. This applies to a…
Baryon Form Factors of Relativistic Constituent-Quark Models
B. Julia-Diaz, D. O. Riska, F. Coester
The electromagnetic and axial form factors of the nucleon and its lowest positive parity excitations, the Delta(1232) and the N*(1440), are calculated with constituent-quark models…
Stable pentaquarks in the constituent quark model
Fl. Stancu, D. O. Riska
The stability of strange pentaquarks is studied in a constituent quark model based on a flavor-spin hyperfine interaction between quarks. With this interaction model,…
The Coupling of eta Mesons to Quarks and Baryons from D_s^* -> D_s pi^0 Decay
T. A. Lahde, D. O. Riska
The known ratio of the branching fractions for D_s^* --> D_s pi^0 and D_s^* --> D_s gamma may be used to extract the coupling of eta mesons to strange quarks once the value of the…
