Parton intrinsic motion: unpolarized cross sections and the Sivers effect in inclusive particle production
U. D'Alesio, F. Murgia
We present a detailed study, performed in the framework of LO perturbative QCD with the inclusion of spin and k_T effects, of unpolarized cross sections for the Drell-Yan process a…

The role of intrinsic in semi-inclusive Deep Inelastic Scattering (SIDIS) processes () is studied within QCD parton model at leading order. The resul…

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…

U. D'Alesio, S. Melis, F. Murgia
We present a calculation of single and double spin asymmetries for inclusive hadron production in hadronic collisions. Our approach is based on Leading Order (LO) perturbative QCD…
QCD instantons in high energy diffractive scattering: Instanton model of Pomeron
A. E. Dorokhov, I. O Cherednikov
The role of the QCD vacuum effects in high energy diffractive quark-quark and quark-antiquark scattering is studied with the Instanton Liquid Model. The special attention is given…
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…
Entropy production and Pesin-like identity at the onset of chaos
Roberto Tonelli, Giuseppe Mezzorani, Franco Meloni +2
Asymptotically entropy of chaotic systems increases linearly and the sensitivity to initial conditions is exponential with time: these two behaviors are related. Such relationship…
Study of instanton effects in electromagnetic quark form factor at high energy
A. E. Dorokhov, I. O. Cherednikov
The detailed analysis of nonperturbative contributions to the electromagnetic quark form factor is performed within the framework of the instanton liquid model (ILM) of the QCD vac…
Measurement of the Radiative Ke3 Branching Ratio
NA48 collaboration
We present a measurement of the relative branching ratio of the decay KL -> pi e nu gamma (Ke3gamma) with respect to KL-> pi e nu (gamma) (Ke3+Ke3gamma) decay. The result is based…
Acoustic analogs of two-dimensional black holes
Mariano Cadoni
We present a general method for constructing acoustic analogs of the black hole solutions of two-dimensional (2D) dilaton gravity. Because by dimensional reduction every sphericall…

E. N. Antonov, L. N. Lipatov, E. A. Kuraev +1
Starting from the gauge invariant effective action in the quasi-multi-Regge kinematics (QMRK), we obtain the effective reggeized gluon (R) -- particle (P) vertices of the following…
Two-dimensional static black holes with pointlike sources
M. Melis, S. Mignemi
We study the static black hole solutions of generalized two-dimensional dilaton-gravity theories generated by pointlike mass sources, in the hypothesis that the matter is conformal…

The semileptonic decay of the neutral K meson, KL -> pi e nu (Ke3), was used to study the strangeness-changing weak interaction of hadrons. A sample of 5.6 million reconstructed ev…

U. Bottigli, P. Cerello, S. Cheran +14
The GPCALMA (Grid Platform for Computer Assisted Library for MAmmography) collaboration involves several departments of physics, INFN sections, and italian hospitals. The aim of th…
Single-spin asymmetries: the Trento conventions
Alessandro Bacchetta, Umberto D'Alesio, Markus Diehl +1
During the workshop "Transversity: New Developments in Nucleon Spin Structure" (ECT*, Trento, Italy, 14-18 June 2004), a series of recommendations was put forward by the participan…
First-principles generation of Stereographic Maps for high-field magnetoresistance in normal metals: an application to Au and Ag
Roberto De Leo
About thirty high-field magnetoresistance Stereographic Maps have been measured for metals between Fifties and Seventies but no way was known till now to compare these complex expe…
Two-parameter deformations of logarithm, exponential, and entropy: A consistent framework for generalized statistical mechanics
G. Kaniadakis, M. Lissia, A. M. Scarfone
A consistent generalization of statistical mechanics is obtained by applying the maximum entropy principle to a trace-form entropy and by requiring that physically motivated mathem…
