Perspectives for Direct CP Violation Tests in Hyperon Decays

M. Conte, E. Di Salvo, A. Penzo +1

We discuss the perspectives of measuring direct CP violation parameters in hyperon decays by measurements with proton and/or antiproton beams, to be carried out at various faciliti…

Resonant states channels of Charmonium

E. Di Salvo, M. Pallavicini, E. Robutti

We employ QCD sum rules, implemented with two numerical algorithms already tested in two different channels of Charmonium, in order to predict masses of resonances just above the g…

Problems in the resummation of soft-gluon effects in the transverse-momentum distributions of massive vector bosons in hadronic collisions

S. Frixione, P. Nason, G. Ridolfi

We consider the resummation of soft-gluon emission in the transverse-momentum distribution of vector mesons in hadronic collisions. We find that the resummed expression in the impa…

Are Parton Distributions Positive?

Stefano Forte, Guido Altarelli, Giovanni Ridolfi

We show that the naive positivity conditions on polarized parton distributions which follow from their probabilistic interpretation in the naive parton model are reproduced in pert…

On positivity of parton distributions

Guido Altarelli, Stefano Forte, Giovanni Ridolfi

We discuss the bounds on polarized parton distributions which follow from their definition in terms of cross section asymmetries. We spell out how the bounds obtained in the naive…

Theoretical Analysis of Polarized Structure Functions

G. Altarelli, R. D. Ball, S. Forte +1

We review the analysis of polarized structure function data using perturbative QCD at next-to-leading order. We use the most recent experimental data to obtain updated results for…
