Meson Spectra from an Effective Light Cone Qcd-inspired Model
Abstract I present some recent applications of a light cone QCD-inspired model with the mass squared operator consisting of a harmonic oscillator potential as confinement in the meson spectra. The model gives an universal and satisfactory description of both singlet and triplet states of S-wave mesons. In the present work P -wave Ds mesons are also investigated. The mass of the recently found m...
متن کاملUniversal description of S-wave meson spectra in a renormalized light-cone QCD-inspired model
A light-cone QCD-inspired model, with the mass squared operator consisting of a harmonic oscillator potential as confinement and a Dirac-delta interaction, is used to study the S-wave meson spectra. The two parameters of the harmonic potential and quark masses are fixed by masses of ρ(770), ρ(1450), J/ψ, ψ(2S), K(892) and B. We apply a renormalization method to define the model, in which the ps...
متن کاملLight-cone QCD predictions for elastic ed-scattering in the intermediate energy region
The contributions of helicity-flip matrix elements to the deuteron form factors are discussed in the light-cone frame. Normalized A(Q), B(Q), GQ(Q ) and T20 are obtained in a simple QCD-inspired model. We find that G + +− plays an important role in GQ(Q ). Our numerical results are consistent with the data in the intermediate energy region. 13.40.Gp, 12.38.Bx, 24.85.+p, 27.10.+h Typeset using R...
متن کاملA QUADRATIC MARGIN-BASED MODEL FOR WEIGHTING FUZZY CLASSIFICATION RULES INSPIRED BY SUPPORT VECTOR MACHINES
Recently, tuning the weights of the rules in Fuzzy Rule-Base Classification Systems is researched in order to improve the accuracy of classification. In this paper, a margin-based optimization model, inspired by Support Vector Machine classifiers, is proposed to compute these fuzzy rule weights. This approach not only considers both accuracy and generalization criteria in a single objective fu...
متن کاملScale dependence of the chiral - odd twist - 3 distributions h L ( x ) and e ( x )
Scale dependence of the chiral-odd twist-3 distributions h L (x) and e(x) Abstract We evaluate the complete leading-order evolution kernels for the chiral-odd twist-3 distributions e(x) and h L (x) of the nucleon. We establish the connection between the evolution equations in light-cone position and light-cone fraction representations, which makes a correspondence between the non-local string o...
