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…

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…

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…

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…
