Investigation of N-N* Electromagnetic Form Factors within a Front-Form CQM
E. Pace, G. Salme`, S. Simula
The helicity amplitudes for the transitions and are presented. The amplitudes have been obtained within our front-form CQM model, based on hadron eigenstates…
Analysis of the Lambda_b -> Lambda_c + l nu_l decay within a light-front constituent quark model
F. Cardarelli, S. Simula
We present an investigation of the Isgur-Wise form factor relevant for the semileptonic decay Lambda_b -> Λ_c + l nu_l performed within a light-front constituent quark model. Adopt…
Light-Baryon Spectroscopy and the Electromagnetic Form Factors in the Quark Model
F. Cardarelli, E. Pace, G. Salme' +1
The momentum distributions of the constituent quarks inside the nucleon and the prominent electroproduced nucleon resonances are investigated in the two most sophisticated, availab…
Longitudinal and transverse structure functions of proton and deuteron at large x
G. Ricco, S. Simula
Higher-twist effects in the low-order moments of the longitudinal and transverse structure functions of proton and deuteron have been analyzed using available phenomenological fits…
The light baryon spectrum and the exchange of pseudoscalar and vector mesons among constituent quarks
F. Cardarelli, S. Simula
The effects of the exchanges of both pseudoscalar and vector mesons among constituent quarks on the mass spectra of light baryons are investigated, paying particular attention to t…
Lepton asymmetries in exclusive decays as a test of the Standard Model
D. Melikhov, N. Nikitin, S. Simula
We argue that the longitudinal lepton polarization and the forward-backward asymmetries in exclusive decays are largely unaffected by the theoretical unc…
