Nonextensive statistics in stellar plasma and solar neutrinos

A. Lavagno, P. Quarati

Nonextensive and quantum uncertainty effects (related to the quasiparticles composing the stellar core) have strong influence on the nuclear rates and, of course, affect solar neut…

Reply Comment on "Entropy of 2D black holes from counting microstates"

Mariano Cadoni, Salvatore Mignemi

We show that the arguments proposed by Park and Yee against our recent derivation of the statistical entropy of 2D black holes do not apply to the case under consideration

Off-Equilibrium Dynamics at Very Low Temperatures in 3d Spin Glasses

E. Marinari, G. Parisi, F. Ricci-Tersenghi +1

We present a high statistic systematic study of the overlap correlation function well below the critical temperature in the three dimensional Gaussian spin glass. The off-equilibri…

Primary scalar hair in dilatonic theories with modulus fields

S. Mignemi

We study the general spherical symmetric solutions of dilaton-modulus gravity non-minimally coupled to a Maxwell field, using methods from the theory of dynamical systems. We show…

A new measurement of direct CP violation in two pion decays of the neutral kaon

The NA48 Collaboration, V. Fanti

The NA48 experiment at CERN has performed a new measurement of direct CP violation, based on data taken in 1997 by simultaneously collecting K_L and K_S decays into pi0pi0 and pi+p…

Predictions for single spin asymmetries in lepton + p(transv. polarized) -> pion + X and gamma^* + p(transv. polarized) -> pion + X

M. Anselmino, M. Boglione, J. Hansson +1

Predictions for the single transverse spin asymmetry A_N in semi-inclusive DIS processes are given; non negligible values of A_N may arise from spin effects in the fragmentation of…

Single transverse spin asymmetries in inclusive hadron production

M. Anselmino, M. Boglione, F. Murgia

A consistent phenomenological approach to the computation of transverse single spin asymmetries in inclusive hadron production is presented, based on the assumed generalization of…

Helioseismology and Beryllium neutrino

B. Ricci, F. L. Villante, M. Lissia

We derive a lower limit on the Beryllium neutrino flux on earth, , in the absence of oscillations, by using helioseismic data, the B-neutr…

Dimensional reduction of 4d heterotic string black holes

Mariano Cadoni

We perform the spherical symmetric dimensional reduction of heterotic string theory. We find a class of two-dimensional (2d) dilaton gravity models that gives a general d…

Vacuum oscillations and excess of high energy solar neutrino events observed in Superkamiokande

V. Berezinsky, G. Fiorentini, M. Lissia

The excess of solar-neutrino events above 13 MeV that has been recently observed by Superkamiokande can be explained by the vacuum oscillation solution to the Solar Neutrino Proble…

Off-diagonal helicity density matrix elements for vector mesons produced in polarized e+e- processes

M. Anselmino, M. Bertini, F. Caruso +2

Final state quark-antiquark interactions give origin to non zero values of the off-diagonal element rho_{1,-1} of the helicity density matrix of vector mesons produced in e+e- anni…

Numerical Simulations of the 4D Edwards-Anderson Spin Glass with Binary Couplings

E. Marinari, F. Zuliani

We present numerical results that allow a precise determination of the transition point and of the critical exponents of the 4D Edwards-Anderson Spin Glass with binary quenched ran…

Asymptotic symmetries of AdS_2 and conformal group in d=1

Mariano Cadoni, Salvatore Mignemi

We present a detailed discussion of the asymptotic symmetries of Anti-de Sitter space in two dimensions and their relationship with the conformal group in one dimension. We use thi…

Solar neutrino fluxes with arbitrary He3 mixing

V. Berezinsky, G. Fiorentini, M. Lissia

The He3 abundance is not constrained by helioseismic data. Mixing of He3 inside the solar core by processes not included in the solar standard model (SSM) has been recently propose…

Phenomenology of single spin asymmetries in p(transv. polarized)-p -> pion + X

Mauro Anselmino, Maria Boglione, Francesco Murgia

A phenomenological description of single transverse spin effects in hadron-hadron inclusive processes is proposed, assuming a generalized factorization scheme and pQCD hard interac…
