Nucleon-nucleon scattering in a chiral constituent quark model
We study the nucleon-nucleon interaction in a chiral constituent quark model by using the resonating group method, convenient for treating the interaction between composite particles. The calculated phase shifts for the S1 and S0 channels show the presence of a strong repulsive core due to the combined effect of the quark interchange and the spin-flavour structure of the effective quark-quark i...
متن کاملThe Nucleon-nucleon Interaction in a Chiral Constituent Quark Model
We study the short-range nucleon-nucleon interaction in a chiral constituent quark model by diagonalizing a Hamiltonian comprising a linear confinement and a Goldstone boson exchange interaction between quarks. The six-quark harmonic oscillator basis contains up to two excitation quanta. We show that the highly dominant configuration is | sp[42]O [51]FS > due to its specific flavour-spin symmet...
متن کاملNucleon-Nucleon interaction in a chiral constituent quark model
We study the nucleon-nucleon (NN) problem as a six-quark system in a nonrelativistic chiral constituent quark model where the Hamiltonian contains a linear confinement and a pseudoscalar meson (Goldstone boson) exchange interaction between the quarks. This interaction has a long range Yukawa-type part, depending on the mass of the exchanged meson and a short range part, mainly responsible for t...
متن کاملThe Nucleon-Nucleon Interaction in a Chiral Constituent Quark Model
Acknowledgments First and foremost, I wish to express my deep gratitude to my supervisor Fl. Stancu for giving me inspiration and guidance in the research work contained in this thesis. I am very grateful to her for prompt help whenever I needed it. Her professional and human support was so fundamental that it is really hard to estimate what a chance I had meeting her. I would also like to than...
متن کاملNucleon Electromagnetic Form Factors in a chiral constituent-quark model
The electromagnetic form factors of the nucleon are calculated in an extended chiral constituent-quark model where the effective interaction is described by the exchange of pseudoscalar, vector, and scalar mesons. Two-body current-density operators, constructed consistently with the extended model Hamiltonian in order to preserve gauge invariance and current conservation, are found to give a si...
