QCD analysis of first b cross section data at 1.96 TeV

M. Cacciari, S. Frixione, M. L. Mangano +2

The first data on bottom quark production in p-pbar collisions at 1.96 TeV have recently been obtained by the CDF collaboration. These data probe the region of pt~0, providing a ne…

A rigorous bound on quark distributions in the nucleon

E. Di Salvo

I deduce an inequality between the helicity and the transversity distribution of a quark in a nucleon, at small energy scales. Then I establish, thanks to the positivity constraint…

Spectroscopy of pentaquark states

R. Bijker, M. M. Giannini, E. Santopinto

We construct a complete classification of pentaquark states in terms of the spin-flavour SU(6) representations. We find that only some definite SU(3) representations are allowed, s…

Jet and Di-Jet production in Photon-Photon collisions

L. Bertora

We present next-to-leading order QCD predictions for single-inclusive and di-jet observables, relevant to the collisions of two on-shell photons, obtained with a recently completed…

New extraction of alpha_s(MZ) from proton DIS data

S. Simula, M. Osipenko

An exploratory study for a new determination of the strong coupling constant alpha_s(MZ) from existing world data on the proton structure function F2p in the Q**2-range from ~ 5 to…

Matching NLO QCD and parton showers in heavy flavour production

S. Frixione, P. Nason, B. R. Webber

We apply the MC@NLO approach to the process of heavy flavour hadroproduction. MC@NLO is a method for matching next-to-leading order (NLO) QCD calculations and parton shower Monte C…

The t-tbar cross-section at 1.8 and 1.96 TeV: a study of the systematics due to parton densities and scale dependence

M. Cacciari, S. Frixione, M. L. Mangano +2

We update the theoretical predictions for the t-tbar production cross-section at the Tevatron, taking into account the most recent determinations of systematic uncertainties in the…

Possible evidence of extended objects inside the proton

R. Petronzio, S. Simula, G. Ricco

Recent experimental determinations of the Nachtmann moments of the inelastic structure function of the proton F2p(x, Q**2), obtained at Jefferson Lab, are analyzed for values of th…

A Kinematically Complete Measurement of the Proton Structure Function F2 in the Resonance Region and Evaluation of Its Moments

M. Osipenko, G. Ricco, M. Taiuti +3

We measured the inclusive electron-proton cross section in the nucleon resonance region (W < 2.5 GeV) at momentum transfers Q**2 below 4.5 (GeV/c)**2 with the CLAS detector. The la…
