Constraining Spectral Functions at Finite Temperature and Chemical Potential with Exact Sum Rules in Asymptotically Free Theories
Suzhou HUANG, Marcello LISSIA
Within the framework of the operator product expansion (OPE) and the renormalization group equation (RGE), we show that the temperature and chemical potential dependence of the zer…
Mass corrections in decay and the role of distribution amplitudes
Francesco Murgia, Maurizio Melis
We consider mass correction effects on the polar angular distribution of a baryon--antibaryon pair created in the chain decay process , generalizing a pr…
Black holes in generalized dilaton gravity in two dimensions
S. Mignemi
We consider two-dimensional dilaton-gravity theories with a generic exponential potential for the dilaton, and obtain the most general black hole solutions in the Schwarzshild form…
The Relevant Scale Parameter in the High Temperature Phase of QCD
Suzhou Huang, Marcello Lissia
We introduce the running coupling constant of QCD in the high temperature phase, , through a renormalization scheme where the dimensional reduction is optimal at th…
Single Spin Asymmetry in Inclusive Pion Production
Mauro Anselmino, M. E. Boglione, F. Murgia
It is shown how the single spin asymmetry observed in inclusive pion production is related, in the helicity basis, to the imaginary part of the product of two different distributio…
Non-singular four-dimensional black holes and the Jackiw-Teitelboim theory
M. Cadoni, S. Mignemi
A four-dimensional dilaton-gravity action whose spherical reduction to two dimensions leads to the Jackiw-Teitelboim theory is presented. A nonsingular black hole solution of the t…
Where are the beryllium neutrinos?
S. Degl'Innocenti, G. Fiorentini, M. Lissia
We show that present experiments imply that neutrinos are nonstandard at the 87\% C.L., independently of solar or nuclear physics. Moreover, if neutrinos are standard, the Be f…
The MSW solution to the solar neutrino problem for non-standard solar models
V. Berezinsky, G. Fiorentini, M. Lissia
The difficulties for non-standard solar models (NSSM) in resolving the solar neutrino problem are discussed stressing the incompatibility of the gallium--Kamiokande data, and of th…
Cosmological and Wormhole Solutions in Low-Energy Effective String Theory
Mariano Cadoni, Marco Cavaglia
We derive and study a class of cosmological and wormhole solutions of low-energy effective string field theory. We consider a general four-dimensional string effective action where…
Neutrinos from the Sun: experimental results confronted with solar models
Vittorio Castellani, Scilla Degl'innocenti, Gianni Fiorentini +2
For standard neutrinos, recent solar neutrino results together with the assumption of a nuclearly powered Sun imply severe constraints on the individual components of the total neu…
Duality of Lorentzian and Euclidean black holes in two-dimensional string-generated models
M. Cadoni, S. Mignemi
We discuss the properties of lorentzian and euclidean black hole solutions of a generalized 2-dim dilaton-gravity action containing a modulus field, which arises from the compactif…
An Interesting Charmonium State Formation and Decay :
M. Anselmino, F. Caruso, F. Murgia +1
Massless perturbative QCD forbids, at leading order, the exclusive annihilation of proton-antiproton into some charmonium states, which, however, have been observed in the $p\bar p…
Classical and Semiclassical Properties of Extremal Black Holes with Dilaton and Modulus Fields
M. Cadoni, S. Mignemi
We discuss both classical and semiclassical properties of extremal black holes in theories where the dilaton and a modulus field are present. We find that the corresponding 2-dim g…
