Benvenuti nell'Anagrafe della Ricerca d'Ateneo
La valutazione delle attività di ricerca che si svolgono nelle università ha assunto un'importanza rilevante sia per l'intero sistema universitario sia all'interno di ogni singolo ateneo. Roma Tre si è quindi dotata di idonei strumenti informativi in grado di supportare al meglio le azioni di monitoraggio e di valutazione delle attività di ricerca svolte nei propri dipartimentied ha realizzato una Anagrafe della Ricerca di Ateneo.
EnglishA novel analysis of the electroweak radiative corrections to e+ + e- --> f + fBAR, carried out in three different schemes, is presented. The first parametrizes the corrections in terms of G-mu, m(Z) and sin2-theta-W = 1 - m(W)2/m(Z)2 and employs recently proposed renormalized self-energies satisfying simple renormalization conditions. The second is parametrized in terms of m(Z) and the MSBAR couplings e2(m(Z)) and sin2-theta-W(m(Z)). The third introduces an effective gauge-invariant angle sin2-theta-W(eff). Compact formulae to evaluate the differential cross sections, partial widths and asymmetries are given. A numerical comparison is made of various predictions obtained on the basis of the first two schemes as well as on Hollik's formulation.

The first parametrizes the corrections in terms of G-mu, m(Z) and sin2-theta-W = 1 - m(W)2/m(Z)2 and employs recently proposed renormalized self-energies satisfying simple renormalization conditions. The second is parametrized in terms of m(Z) and the MSBAR couplings e2(m(Z)) and sin2-theta-W(m(Z)). The third introduces an effective gauge-invariant angle sin2-theta-W(eff). Compact formulae to evaluate the differential cross sections, partial widths and asymmetries are given.
