Sea-quark effects in the pion charge form factor
Q. B. Li, D. O. Riska
It is shown that the data on the pion charge form factor admit the possibility for a substantial sea-quark components in the pion wave function. If the charge form factor is calcul…
The Role of 5-quark Components on the Nucleon Form Factors
Q. B. Li, D. O. Riska
The covariant quark model is shown to allow a phenomenological description of the neutron electric form factor, G_E^n(Q^2), in the impulse approximation, provided that the wave fun…
The role of components in the N(1440) resonance
Q. B. Li, D. O. Riska
The role of 5-quark components in the pion and electromagnetic decays and transition form factors of the N(1440) is explored. The components, where the 4-quark subsyst…
Five-quark components in decay
Q. B. Li, D. O. Riska
Five-quark components in the are shown to contribute significantly to decay through quark-antiquark annihilation transitions. These involve t…
pentaquark in the nuclear medium
M. J. Vicente Vacas, D. Cabrera, Q. B. Li +2
We study the interaction of the pentaquark with nuclear matter associated to the decay channels and to the two meson cloud. We find that the potential is attractive and…
Interaction of the with the nuclear medium
M. J. Vicente Vacas, D. Cabrera, Q. B. Li +2
We study the selfenergy of the pentaquark in nuclei associated with two types of interaction: the KN decay of the and two meson baryon decay channels of the . Wher…
