(SISSA Library, 1982)The role of multiple quark scattering subprocesses in large-Pt jet production from high-energy hadron-hadron collisions is discussed. In particular, the connection with multiconstituent distributions is emphasized.
-
(SISSA Library, 1982)Photons emitted by massive photinos (γ) formed in the hot big bang could ionise the intergalactic medium and galactic halos to the observed extent if mγ ~ 100 eV and the radiative lifetime τ ~ 1027 s. These photinos could ...

(SISSA Library, 1982)In this paper we derive in a completely rigorous way a family of inequalities holding for proper combinations of the squared norms of the states generated by the quantum evolution of a composed quantum system in the presence ...

(SISSA Library, 1982)It is shown that the s → 1,0 limit of the Potts gauge model describes plaquettes percolation as the analogous limit of the spin model describes the bond percolation. These results strengthen further the connection between ...
-
(SISSA Library, 1982)A relativistic quantum field theory is presented where point-like dyons describe closed spacetime trajectories and are coupled to e.m. field degrees of freedom, a path integral over trajectories and a functional integration ...

-
(SISSA Library, 1982)We present a model of a bi—excitonic molecule, consisting of two electrons and two holes bound together in a quasi—one—dimensional semiconductor. The problem is solved exactly in principle following the Hyperspheric Harmonic ...

-
(SISSA Library, 1982)We study the covariance properties of Murai’s, Dirac—Murai’s and Todorov’s spinor wave equations in the whole M2N,2 space with respect to SO(2N,2) group rotations. These rotations are in two—to—one correspondence with the ...
-
(SISSA Library, 1982)A non-perturbative treatment of the infrared problem in quantum electrodynamics is presented Starting from the local and covariant correlation functions of the Gupta-Bleuler formulation an explicit construction of the ...

-
(SISSA Library, 1982)I propose a method to relate perturbative to non perturbative QCD parameters using the available e+ e- data. The method reproduces "standard" results, but needs a rather large strange quark "mass" 11 H 250MeV assuming ...
-
(Società Italiana di Fisica, 1982)We study the curvature dependence of the quartic self-coupling constant in a λØ 4 theory in the background of e static closed Einstein universe. Contrary of what happens in flat space-time at finite temperature we find ...
-
(SISSA Library, 1982)It is proposed that the dark matter near the sun associated with the Oort limit be identified as belonging to a flattened rotating system of massive neutrinos or photinos. Further out this system may become the previously ...
-
(SISSA Library, 1982)The next-to-leading--logarithmic corrections to the helicity cross- sections for the Drell-Yan process are calculated. While it is well-known that these corrections are large, it is shown here that when considering the ...
-
(SISSA Library, 1982)We estimated that the ratio a/m between the specific angular momentum "a" and the total mass "m" (both the geometrized units) of the cores of massive main sequence stars exceeds the same ratio of neutron stars of about ...
