Spin and flavor projection operators in the spin-flavor group
Victor Miguel Banda Guzman, Ruben Flores-Mendieta, Johann Hernandez +1
The quadratic Casimir operator of the special unitary group is used to construct projection operators, which can decompose any of its reducible finite-dimensional represent…
Baryon quadrupole moment in the 1/N(c) expansion of QCD
Victor Miguel Banda Guzman, Ruben Flores-Mendieta, Johann Hernandez +1
The quadrupole moments of ground state baryons are discussed in the framework of the 1/N(c) expansion of QCD, where N(c) is the number of color charges. Theoretical expressions are…
Breaking so(4) symmetry without degeneracy lift
A. Pallares-Rivera, F. de J. Rosales-Aldape, M. Kirchbach
We argue that in the quantum motion of a scalar particle of mass "m" on S^3_R perturbed by the trigonometric Scarf potential (Scarf I) with one internal quantized dimensionless par…
