On the potential role of the Collins effect in A_N in pp --> pion X

M. Anselmino, M. Boglione, U. D'Alesio +4

Transverse single spin asymmetries in pp --> pion X processes, while on a quite firm ground experimentally, are still a much debated phenomenological issue. We consider them in a t…

On the role of Collins effect in the single spin asymmetry A_N in p(transv. polarized) p --> h X processes

M. Anselmino, M. Boglione, U. D'Alesio +4

The much debated issue of the transverse single spin asymmetry A_N observed in the inclusive large P_T production of a single hadron in pp interactions, p(transv. polarized) p -->…

On the controversy concerning the definition of quark and gluon angular momentum

Elliot Leader

A major controversy has arisen in QCD as to how to split the total angular momentum into separate quark and gluon contributions, and as to whether the gluon angular momentum can it…

On the importance of Lorentz structure in the parton model: target mass corrections, transverse momentum dependence, positivity bounds

U. D'Alesio, E. Leader, F. Murgia

We show that respecting the underlying Lorentz structure in the parton model has very strong consequences. Failure to insist on the correct Lorentz covariance is responsible for th…

Sivers and Collins effects in polarized pp scattering processes

M. Anselmino, M. Boglione, U. D'Alesio +3

We summarize the present phenomenology of Sivers and Collins effects for transverse single spin asymmetries in polarized proton-proton collisions within the framework of the genera…

Helicity Formalism and Spin Asymmetries in Hadronic Processes

M. Anselmino, M. Boglione, U. D'Alesio +3

We present a generalized QCD factorization scheme for the high energy inclusive polarized process, (A, S_A) + (B, S_B) -> C + X, including all intrinsic partonic motions. This intr…

Can the Collins mechanism explain the large transverse single spin asymmetries observed in p(transv. polarized) p --> pion X?

M. Anselmino, M. Boglione, U. D'Alesio +2

We present a calculation of inclusive polarised and unpolarised cross sections within pQCD and the factorisation scheme, taking into account the parton intrinsic motion, k_T, in di…

The Gluon Sivers Distribution in D production at RHIC

M. Anselmino, M. Boglione, E. Leader +2

The single transverse spin asymmetry in D meson production at RHIC can provide a clean measure of the gluon Sivers distribution function. At intermediate rapidity, D production is…

Single spin asymmetries in DIS

M. Anselmino, E. Leader, F. Murgia

We consider possible mechanisms for single spin asymmetries in inclusive Deep Inelastic Scattering (DIS) processes with unpolarized leptons and transversely polarized nucleons. Tes…

An exact sum rule for transversely polarized DIS

A. V. Efremov, E. Leader, O. V. Teryaev

The Operator Product Expansion provides expressions for the moments of and in terms of hadronic matrix elements of local operators for odd integer.…
