Thermal distributions in stellar plasmas, nuclear reactions and solar neutrinos

M. Coraddu, G. Kaniadakis, A. Lavagno +3

The physics of nuclear reactions in stellar plasma is reviewed with special emphasis on the importance of the velocity distribution of ions. Then the properties (density and temper…

Entropy of 2D black holes from counting microstates

Mariano Cadoni, Salvatore Mignemi

We present a microscopical derivation of the entropy of the black hole solutions of the Jackiw-Teitelboim theory. We show that the asymptotic symmetry of two-dimensional (2D) Anti-…

Single spin asymmetries in transversely polarized proton(antiproton) - proton inclusive processes

Mauro Anselmino, Francesco Murgia

We consider several single spin asymmetries in inclusive, transversely polarized proton(antiproton) - proton processes as higher twist QCD contributions, taking into account spin a…

High energy photon-neutrino interactions

Ali Abbasabadi, Alberto Devoto, Duane A. Dicus +1

A general decomposition of the amplitudes for the processes and is obtained using gauge invariance and Bose symmetry. The restrictions implied by t…

Helioseismic tests of diffusion theory

G. Fiorentini, M. Lissia, B. Ricci

We present a quantitative estimate of the accuracy of the calculated diffusion coefficients, by comparing predictions of solar models with observational data provided by helioseism…

Off-diagonal helicity density matrix elements for heavy vector mesons inclusively produced in N-N, gamma-N, l-N interactions

M. Anselmino, M. Bertini, F. Murgia +1

Final state interactions in quark fragmentation may give origin to non zero values of the off-diagonal element rho_(1,-1) of the helicity density matrix of vector mesons V produced…

Neutrino self-energy and dispersion in a medium with magnetic field

A. Erdas, C. W. Kim, T. H. Lee

We calculate the one-loop thermal self-energy of a neutrino in a constant and homogeneous magnetic field to all orders in the magnetic field strength using Schwinger's proper time…

2D Extremal Black Holes as Solitons

M. Cadoni

We discuss the relationship between two-dimensional (2D) dilaton gravity models and sine-Gordon-like field theories. We show that there is a one-to-one correspondence between the s…

The dynamical structure of four-dimensional Chamseddine's gauge theory of gravity

S. Mignemi

We perform the Dirac hamiltonian analysis of a four-dimensional gauge theory of gravity with an action of topological type, which generalizes some well-known two-dimensional models…

Mean-field behavior of the sandpile model below the upper critical dimension

Alessandro Chessa, Enzo Marinari, Alessandro Vespignani +1

We present results of large scale numerical simulations of the Bak, Tang and Wiesenfeld sandpile model. We analyze the critical behavior of the model in Euclidean dimensions $2\leq…
