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…
QCD Sum Rule Analysis of B \to (K,K^*) (\ell^+\ell^-,ν\barν) Decays
Pietro Santorelli
We use three-point QCD sum rules to calculate the form factors governing the rare exclusive decays B \to (K,K^*) \ell^+ \ell^-, B \to (K,K^*) ν\barν. We predict the branching ratio…
Non-Leptonic Two-Body Weak Decays of Charmed Mesons and CP-Violating Asymmetries
Pietro Santorelli
The non-leptonic two body decays of D mesons are studied in the framework of an improved factorization approximation. The final state interaction effects are taken into account ass…
Statistical Inspired Parton Distributions and the Violation of QPM Sum Rules
F. Buccella, I. Dorusner, G. Miele +3
A quantum statistical parametrization of parton distributions has been considered. In this framework, the exclusion Pauli principle connects the violation of the Gottfried sum rule…
