A quark core-gluon model for heavy hybrid baryons
Lorenzo Cimino, Cintia T. Willemyns, Claude Semay
Besides the ordinary hadrons, QCD allows the existence of states in which excitations of the gluonic field can play the role of valence particles, either alone in a glueball, or co…
Target normal single-spin asymmetry in inclusive electron-nucleon scattering in the 1/Nc expansion
Jose L. Goity, Christian Weiss
The target normal single-spin asymmetry in electron nucleon scattering is studied in the framework of the 1/Nc expansion of QCD, which allows for a rigorous description in the ener…
Target normal single-spin asymmetry in inclusive electron-nucleon scattering in the 1/Nc expansion
Jose L. Goity, Christian Weiss, Cintia Willemyns
The target normal single-spin asymmetry in inclusive electron-nucleon scattering is studied in the low-energy regime that includes the resonance. The particular interest in the…
Target normal single-spin asymmetry in inclusive electron-nucleon scattering with two-photon exchange: Analysis using expansion
J. L. Goity, C. Weiss, C. T. Willemyns
We calculate the target normal single-spin asymmetry caused by two-photon exchange in inclusive electron-nucleon scattering in the resonance region. Our analysis uses the e…
Many-quark interactions: Large- scaling and contribution to baryon masses
F. Buisseret, C. Semay, C. T. Willemyns
Starting from an effective Hamiltonian modelling a baryon made of identical quarks in the large- approach of QCD, we obtain analytical formulas allowing to estimate the cont…
Improvement of the Envelope Theory for Systems with Different Particles
Cyrille Chevalier, Cintia T. Willemyns, Lorenzo Cimino +1
The envelope theory is a method to compute approximate eigensolutions of quantum -body Hamiltonians with a quite general structure in dimensions. The advantages of the metho…
Some specific solutions to the translation-invariant -body harmonic oscillator Hamiltonian
Cintia T. Willemyns, Claude Semay
The resolution of the Schrödinger equation for the translation-invariant -body harmonic oscillator Hamiltonian in dimensions with one-body and two-body interactions is perfo…
Do bras and kets have dimensions?
Claude Semay, Cintia Willemyns
The bra and ket notation introduced by Dirac and the dimensional analysis are two powerful tools for the physicist. Curiously, almost nothing is said about connections between thes…
Envelope Theory for Systems with Different Particles
C. Semay, L. Cimino, C. Willemyns
The eigensolutions of many-body quantum systems are always difficult to compute. The envelope theory is a method to easily obtain approximate, but reliable, solutions in the case o…
Quasi Kepler's third law for quantum many-body systems
C. Semay, C. T. Willemyns
The Kepler's third law is a relation between the period and the energy of two classical particles interacting via a gravitational potential. Recent works showed that this law could…
Towers of baryons of the quark model band in the large limit
C. T. Willemyns, N. N. Scoccola
We performed a complete analysis of the spectrum of all the states in the quark model harmonic oscillator band with in the large limit including the ofte…
Towers of positive parity excited baryons and their mixing in the large limit
Cintia Willemyns, Carlos Schat
We consider configuration mixing for the nonstrange positive parity excited baryons in the and quark…
Operator analysis of effective spin-flavor interactions for L=1 excited baryons
Cintia Willemyns, Carlos Schat
We match the non-relativistic quark model, with both flavor dependent and flavor independent effective quark-quark interactions, to the spin-flavor operator basis of the 1/Nc expan…
