[en] It is shown how to incorporate multiplets with central charges in superconformal gravity. The linear and scalar N = 2 multiplets are presented, and the full superconformal action of scalar multiplets with gauged central charge is given. (orig.)

[en] We give a formulation of the N=2 supersymmetric massive scalar multiplet for which the N=2 supersymmetry algebra closes off shell. The action is given in terms of the fields of the N=2 tensor multiplet. These fields have the unexpected property of vanishing central charge: They correspond to neutral bilinears in the usual physical fields. (orig.)

[en] In this the authors study the automorphisms and derivations of real composition algebras with a view to its physical interpretations. They obtain canonical forms with a special stress in the four and eight dimensional cases. Also, using this description, they work with two mathematical models which describe some particles with certain observables in a surprising way. A first model, split g2, describes two observables for three quarks, their antiquarks, and eight mesons combining the quarks involved. A second one, so(4,4) circle-plus so(2,2), describes all the observables for all quarks (u, d, s, c, b and t)

[en] In this talk current efforts are presented to improve the predicted particle spectra of non-minimal supersymmetric models such as the NMSSM, USSM, CE6SSM etc. A general spectrum generator framework for non-minimal supersymmetric models is put forward, which is based partly on SARAH and SOFTSUSY.

[en] We consider dihadron fragmentation functions, describing the fragmentation of a parton in two unpolarized hadrons, and in particular extended dihadron fragmentation functions, explicitly dependent on the invariant mass, Mh, of the hadron pair. We first rederive the known results on Mh-integrated functions using jet calculus techniques, and then we present the evolution equations for extended dihadron fragmentation functions. Our results are relevant for the analysis of experimental measurements of two-particle-inclusive processes at different energies

[en] An alternative mixing pattern of 2++ mesons f, f', θ leads to the conclusion that θ(1690) can be understood as a particle containing about 90% of glueball state. 18 refs. (author)

[en] A possible connection between the existence of three quark-lepton generations and the triality property of the SO(8) group (the equality between 8-dimensional vectors and spinors) is investigated. 22 refs., 5 figs
