Fusion reactions in plasmas as probe of the high-momentum tail of particle distributions
Massimo Coraddu, Marcello Lissia, Giuseppe Mezzorani +1
In fusion reactions, the Coulomb barrier selects particles from the high-momentum part of the distribution. Therefore, small variations of the high-momentum tail of the velocity di…
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…
Statistical descriptions of nonlinear systems at the onset of chaos
Massmimo Coraddu, Marcello Lissia, Roberto Tonelli
Ensemble of initial conditions for nonlinear maps can be described in terms of entropy. This ensemble entropy shows an asymptotic linear growth with rate K. The rate K matches the…
Sivers function: SIDIS data, fits and predictions
M. Anselmino, M. Boglione, U. D'Alesio +3
The most recent data on the weighted transverse single spin asymmetry A_{UT}^{\sin(ϕ_h-ϕ_S)} from HERMES and COMPASS collaborations are analysed within LO parton model; all transve…
Nuclear astrophysical plasmas: ion distribution functions and fusion rates
Marcello Lissia, Piero Quarati
This article illustrates how very small deviations from the Maxwellian exponential tail, while leaving unchanged bulk quantities, can yield dramatic effects on fusion reaction rate…
Statistical entropy of the Schwarzschild black hole
Mariano Cadoni
We derive the statistical entropy of the Schwarzschild black hole by considering the asymptotic symmetry algebra near the boundary of the spacetime at past null infin…
Comparing extractions of Sivers functions
M. Anselmino, M. Boglione, J. C. Collins +11
A comparison is given of the various recently published extractions of the Sivers functions from the HERMES and COMPASS data on single-transverse spin asymmetries in semi-inclusive…
Acoustic horizons for axially and spherically symmetric fluid flow
M. Cadoni, P. Pani
We investigate the formation of acoustic horizons for an inviscid fluid moving in a pipe in the case of stationary and axi-symmetric flow. We show that, differently from what is ge…
Nonextensive Interpretation Of Radiative Recombination In Electron Cooling
G. Maero, P. Quarati, F. Ferro
An interest for the low-energy range of the nonextensive distribution function arises from the study of radiative recombination in electron cooling devices in particle accelerators…
KamLAND results and the radiogenic terrestrial heat
Gianni Fiorentini, Marcello Lissia, Fabio Mantovani +1
We find that recent results from the KamLAND collaboration on geologically produced antineutrinos, N(U+Th) = 28+16-15 events, correspond to a radiogenic heat production from Uraniu…
Polaron Crossover and Bipolaronic Metal-Insulator Transition in the Holstein model at half-filling
M. Capone, P. Carta, S. Ciuchi
The evolution of the properties of a finite density electronic system as the electron-phonon coupling is increased are investigated in the Holstein model using the Dynamical Mean-F…
Convergence to the Critical Attractor at Infinite and Tangent Bifurcation Points
R. Tonelli
The dynamics of the convergence to the critical attractor for the logistic map is investigated. At the border of chaos, when the Liapunov exponent is zero, the use of the non-exten…
General partonic structure for hadronic spin asymmetries
M. Anselmino, M. Boglione, U. D'Alesio +3
The high energy and large p_T inclusive polarized process, (A, S_A) + (B, S_B) --> C + X, is considered under the assumption of a generalized QCD factorization scheme. For the firs…
Geo-neutrinos: a new probe of Earth's interior
Gianni Fiorentini, Marcello Lissia, Fabio Mantovani +1
In preparation to the experimental results which will be available in the future, we study geo-neutrino production for different models of mantle convection and composition. By usi…
A spacetime realization of kappa-Poincare algebra
S. Mignemi
We study a Hamiltonian realization of the phase space of kappa-Poincare algebra that yields a definition of velocity consistent with the deformed Lorentz symmetry. We are also able…
Extracting the Sivers function from polarized SIDIS data and making predictions
M. Anselmino, M. Boglione, U. D'Alesio +3
The most recent data on the weighted transverse single spin asymmetry from HERMES and COMPASS collaborations are analysed within LO parton model with unint…
Acoustic analogues of black hole singularities
Mariano Cadoni, Salvatore Mignemi
We search for acoustic analogues of a spherical symmetric black hole with a pointlike source. We show that the gravitational system has a dynamical counterpart in the constrained,…
Two-dimensional description of D-dimensional static black holes with pointlike sources
Mariano Cadoni, Salvatore Mignemi
We derive two-dimensional (2D) solutions of a generic dilaton gravity model coupled with matter, which describe D-dimensional static black holes with pointlike sources. The equalit…
Noncommutative QED corrections to e^+e^-\toγγγat linear collider energies
Alberto Devoto, Stefano Di Chiara, Wayne W. Repko
We compute the total cross section as well as angular and energy distributions for process with both unpolarized and polarized beams in the framework of noncommutati…
Hadron Spin Structure: Novel Effects from Transverse Single Spin Asymmetries
U. D'Alesio
Transverse single spin asymmetries can be a challenging tool in our understanding of the internal structure of hadrons. Some aspects and recent results are discussed.
Metastable and stable equilibrium states of stellar electron-nuclear plasmas
F. Ferro, A. Lavagno, P. Quarati
By minimizing free energy density, we show that the stellar core of a hydrogen burning star is not in a global thermodynamical equilibrium unless density, temperature, mass and com…
What entropy at the edge of chaos?
Marcello Lissia, Massimo Coraddu, Roberto Tonelli
Numerical experiments support the interesting conjecture that statistical methods be applicable not only to fully-chaotic systems, but also at the edge of chaos by using Tsallis' g…
The role of Cahn and Sivers effects in Deep Inelastic Scattering
M. Anselmino, M. Boglione, U. D'Alesio +3
The role of intrinsic $\bfk_\perp$ in inclusive and semi-inclusive Deep Inelastic Scattering processes () is studied with exact kinematics within QCD parton mo…
How much Uranium is in the Earth? Predictions for geo-neutrinos at KamLAND
Gianni Fiorentini, Marcello Lissia, Fabio Mantovani +1
Geo-neutrino detection can determine the amount of long-lived radioactive elements within our planet, thus providing a direct test of the Bulk Silicate Earth (BSE) model and fixing…
