Polarized inclusive leptoproduction, $ℓ N \to h X$ , and the hadron helicity density matrix, $ρ (h)$ : possible measurements and predictions

M. Anselmino, M. Boglione, J. Hansson +1

We discuss the production of hadrons in polarized lepton nucleon interactions and in the current jet fragmentation region; using the QCD hard scattering formalism we compute the he…

Glueball plus pion production in hadron collisions

Francesco Murgia, Paul Kessler, Joseph Parisi

Using a non--relativistic gluon bound--state model for glueballs (G), we compute the subprocess $q q ˉ \to G π$ , and we therefrom derive the yield of the overall reaction…

Intermediate Energy Solar Neutrinos

E. Calabresu, G. Fiorentini, M. Lissia +1

We extract information on the fluxes of Be and CNO neutrinos directly from solar neutrino experiments, with minimal assumptions about solar models. Next we compare these results wi…

The Dimensionally Reduced Effective Theory for Quarks in High Temperature QCD

Suzhou Huang, Marcello Lissia

We show that QCD undergoes dimensional reduction at high temperatures also in the quark sector. In the kinematic region relevant to screening physics, where the lowest Matsubara mo…

$χ_{c 2} \to ρρ$ and the $r h o$ polarization in massless perturbative QCD: how to test the distribution amplitudes

Mauro Anselmino, Francesco Murgia

We compute the helicity density matrix of $ρ$ vector mesons produced in the two-body decays of polarized $χ_{c 2}$ 's in the framework of massless perturbative QCD. The $χ_{c 2}$ 's ar…

Contrasting Real-time Dynamics with Screening Phenomena at Finite Temperature

Suzhou Huang, Marcello Lissia

We discuss the interpretation of Euclidean correlation functions at finite temperature ( $T$ ) and their relationship with the corresponding real-time Green's functions. The soluble…

Just So? Vacuum Oscillations and MSW: An Update

E. Calabresu, N. Ferrari, G. Fiorentini +1

We find that vacuum oscillations (VO), large-mixing-angle and small-mixing-angle MSW solutions to the solar neutrino problem (SNP) give all very good fits to the most recent result…

Single spin asymmetry for $p^{↑} p \to π X$ in perturbative QCD

M. Anselmino, M. Boglione, F. Murgia

Within the QCD-improved parton model and assuming the factorization theorem to hold in the helicity basis and for higher twist contributions, we show how non zero single spin asymm…
