Decay Constants and Semileptonic Form Factors of Pseudoscalar Mesons
M. A. Ivanov, P. Santorelli
A relativistic constituent quark model is adopted to give an unified description of the leptonic and semileptonic decays of pseudoscalar mesons (π, K, D, D_s, B, B_s). The calculat…

A Semianalytical Method to Solve Altarelli-Parisi Evolution Equations
Pietro Santorelli, Egidio Scrimieri
We discuss a new method to solve in a semianalytical way the Dokshitzer-Gribov-Lipatov-Altarelli-Parisi evolution equations at NLO order in the x-space. The method allows to constr…
