SU(3)-breaking effects in hyperon semileptonic decays

Silvano Simula

We present the first quenched lattice QCD study of all the vector and axial form factors relevant for the hyperon semileptonic decay Sigma- -> n l nu.

Chiral properties of the constituent quark model

Wolfgang Lucha, Dmitri Melikhov, Silvano Simula

We show that, in a model based exclusively on constituent-quark degrees of freedom interacting via a potential, the full axial current is conserved if the spectrum of \bar QQ state…

Leading and higher twists in proton, neutron and deuteron unpolarized structure functions

Silvano Simula

We summarize the results of a recent global analysis of proton and deuteron F2 structure function world data performed over a large range of kinematics, including recent measuremen…

Experimental moments of the nucleon structure function F2

M. Osipenko, W. Melnitchouk, S. Simula +3

Experimental data on the F2 structure functions of the proton and deuteron, including recent results from CLAS at Jefferson Lab, have been used to construct their n<=12 moments. A…

Dispersion representations and anomalous singularities of the triangle diagram

Wolfgang Lucha, Dmitri Melikhov, Silvano Simula

We discuss dispersion representations for the triangle diagram , the single dispersion representation in and the double dispersion representation in $p_1^…

Constituent quarks, chiral symmetry, and chiral point of the constituent quark model

Wolfgang Lucha, Dmitri Melikhov, Silvano Simula

We construct the full axial current of the constituent quarks by a summation of the infinite number of diagrams describing constituent-quark soft interactions. By requiring that th…
