Transversity and Collins Fragmentation Functions: Towards a New Global Analysis
M. Anselmino, M. Boglione, U. D'Alesio +5
A new, preliminary global analysis of the experimental data on azimuthal asymmetries in SIDIS from HERMES and COMPASS collaborations, and in e+e- --> h_1 h_2 X processes from the B…
Semi-Inclusive Deep Inelastic Scattering processes from small to large P_T
M. Anselmino, M. Boglione, A. Prokudin +1
We consider the azimuthal and dependence of hadrons produced in unpolarized Semi-Inclusive Deep Inelastic Scattering (SIDIS) processes, within the factorized QCD parton model…
The Sivers Function from SIDIS Data
M. Anselmino, M. Boglione, U. D'Alesio +5
We study the Sivers effect in transverse single spin asymmetries (SSA) for pion and kaon production in Semi-Inclusive Deep Inelastic Scattering (SIDIS) processes. We perform a fit…
Transversity and Collins Functions: from e+ e- --> h1 h2 X to SIDIS Processes
M. Anselmino, M. Boglione, U. D'Alesio +4
We present [1] the first simultaneous extraction of the transversity distribution and the Collins fragmentation function, obtained through a combined analysis of experimental data…
Collins Effect from Polarized SIDIS and Data
A. Prokudin, C. Turk
The recent data on the transverse single spin asymmetry from HERMES and COMPASS Collaborations are analysed within LO parton model with unintegrated part…
Critique of an Experiment Regarding Quantum States in a Gravitational Field and Possible Geometrical Explanations
D. Olevik, C. Turk, H. Wiklund +1
We discuss an experiment conducted by Nesvizhevsky et al. As it is the first experiment claimed to have observed gravitational quantum states, it is imperative to investigate all a…
Transversity and Collins functions from SIDIS and e+e- data
M. Anselmino, M. Boglione, U. D'Alesio +4
A global analysis of the experimental data on azimuthal asymmetries in semi-inclusive deep inelastic scattering (SIDIS), from the HERMES and COMPASS Collaborations, and in e+e- -->…

M. Anselmino, M. Boglione, U. D'Alesio +5
We study the Sivers effect in the transverse single spin asymmetries (SSA) for pion and kaon production in semi-inclusive deep inelastic scattering (SIDIS) processes. We perform a…
