Representations of the LL BFKL Kernel and the Bootstrap
G. P. Vacca
Different forms of the BFKL kernel both in coordinate and momentum representations may appear as a result of different gauge choices and/or inner scalar products of the color singl…
Small x QCD
G. P. Vacca
A review of some theoretical aspects of small x QCD physics is given, with a particular emphasis to the relation between the BFKL and the colour dipole approaches. The nonlinear ev…
Jet Vertex in the Next-to-Leading log(s) Approximation
G. P. Vacca
The next-to-leading corrections to the jet vertex which is relevant for the Mueller-Navelet jets production in hadronic collisions and for the forward jet cross section in lepton-h…
Jets at high energies, factorization and jet vertex in NL ln(s)
G. P. Vacca
The next-to-leading corrections to the jet vertex which is relevant for the Mueller-Navelet jets production in hadronic collisions and for the forward jet cross section in lepton-h…
Perturbative QCD Odderon and Diffractive eta_c Production
G. P. Vacca
The Odderon state in perturbative QCD is briefly reviewed. Recent calculations devoted to estimate the diffrative eta_c production at high energies from the leading known Odderon s…
The hard QCD Pomeron: some aspects of its phenomenology and interactions
G. P. Vacca
The Regge limit in perturbative QCD for processes as DIS (low x) and photon or onia-particles scattering is considered. In the first part a phenomenological approach for the inclus…
