    On the Beta Function in Supersymmetric Gauge Theories

    No full text
    We re-examine perturbative and nonperturbative aspects of the beta function in N=1 and N=2 supersymmetric gauge theories, make comments on the recent literature on the subject and discuss the exactness of several known results such as the NSVZ beta function

    Il disegno della cupola del San Carlino alle Quattro Fontane di Borromini: ovale canonico?

    No full text
    The oval that characterizes the dome of the church of San Carlino, designed by Francesco Castelli, called Borromini, is a subject that has always attracted the interest of many scholars. Many design drawings describe a geometric trace of a polycentric curve, or an oval, with a complex plot of lines, some needed to geometrical construction and correspondence with architectural drawing, others of uncertain interpretation. This study aims to investigate the actual role which has the oval shape in the project of San Carlino by comparing the design drawings and the detailed study of the model derived from the survey. In particular this study analyze the sections of the elements where the shape of the oval is present: the tiburium, the coffered dome, the lantern

    Quark number fractionalization in N=2 supersymmetric SU(2)xU(1)(Nf) gauge theories

    No full text
    Physical quark-number charges of dyons are determined, via a formula which generalizes that of Witten for the electric charge, in N = 2 supersymmetric theories with SU(2) x U(1)(Nf) gauge group. The quark numbers of the massless monopole at a nondegenerate singularity of the space of vacua turn out to vanish in all cases. A puzzle related to CP invariant cases is solved. Generalization of our results to SU(N-c) x U(1)(Nf) gauge theories is straightforward

    Dynamical symmetry breaking in supersymmetric SU(n(c)) and USp(2n(c)) gauge theories RID A-4286-2011

    No full text
    We find the phase and flavor symmetry breaking pattern of each N = 1 supersymmetric vacuum of SU(n(C)) and USp(2n(C)) gauge theories, constructed from the exactly solvable N = 2 theories by perturbing them with small adjoint and generic bare hypermultiplet (quark) masses. In SU(n(C)) theories with nf less than or equal to n(C) the vacua are labelled by an integer r, in which the flavor U(nf) symmetry is dynamically broken to U(r) x U(nf - r) in the limit of vanishing bare hyperquark masses. In the I = I vacua the dynamical symmetry breaking is caused by the condensation of magnetic monopoles in the nf representation: For general r, however, the monopoles in the.IC, representation, whose condensation could explain the flavor symmetry breaking but would produce too-many Nambu-Goldstone multiplets, actually "break up" into "magnetic quarks'': the latter with nonabelian interactions condense and induce confinement and dynamical symmetry breaking. In USp(2n(C)) theories with n f less than or equal to n(C) the flavor SO(2nS) symmetry is dynamically broken to U(nf), but with no description in terms of a weakly coupled local field theory. In both SU(n(C)) and USp(2n(C)) theories, with larger numbers of quark flavors, besides the vacua with these properties, there exist also vacua in free magnetic phase, with unbroken global symmetry.

    Una “democrazia su misura”. Riflessioni sulla Repubblica Centrafricana a partire dalla sentenza n. 09/CC/22 della Corte costituzionale

    Il lavoro esamina i recenti avvenimenti costituzionali della Repubblica centrafricana. Dopo aver ricostruito brevemente il contesto storico e politico del Paese, analizza una sentenza del 2022 con la quale la Corte costituzionale ha dichiarato illegittimo il progetto per l’elaborazione di una nuova Costituzione avanzato dal Presidente della Repubblica, per poi soffermarsi sul mancato seguito della decisione da parte dell’esecutivo.Title: A “democracy made to measure”. Reflections on the Central African Republic from Judgment No. 09/CC/22 of the Constitutional Court. Abstract [En]: The work examines recent constitutional events in the Central African Republic. After briefly reconstructing the historical and political context of the Country, it analyses a ruling of 2022 in which the Constitutional Court declared illegitimate the project for the implementation of a new Constitution put forward by the President of the Republic, and then focuses on the executive's failure to follow up on the decision
