Nonlinear realizations describing the spontaneous breakown of supersymme-try and R symmetry are constructed using the Goldstino and R axion fields. The associated R current, supersymmetry current and energy-momentum ten-sor are shown to be related under the nonlinear supersymmetry transformations. Nonlinear realizations of the superconformal algebra carried by these degrees of freedom are also ...

Abstract: The transition of molecular crystals into a polar state is modeled by a one-dimensional Ising Hamiltonian in multipole expansion and a suitable order parameter. Two symmetry breakings are necessary for the transition: the translational and the spin flip invariance—the former being broken by geometric constraints, the latter by the interaction of the first non-zero multipole with the n...

The mixings of d(R) quarks, hidden from view in the standard model (SM), are naturally the largest if one has an Abelian flavor symmetry. With supersymmetry (SUSY) their effects can surface via d(R) squark loops. Squark and gluino masses are at TeV scale, but they can still induce effects comparable to SM in B(d) (or B(s)) mixings, while D0 mixing could be close to recent hints from data. In ge...

In this paper we propose a class of efficient Generalized Method-of-Moments (GMM) algorithms for computing parameters of the Plackett-Luce model, where the data consists of full rankings over alternatives. Our technique is based on breaking the full rankings into pairwise comparisons, and then computing parameters that satisfy a set of generalized moment conditions. We identify conditions for t...

We discuss the model robustness of infinite two-dimensional square grid with respect to symmetry breakings due presence defects, that is, lacks finitely or infinitely many edges. Precisely, we study how these topological perturbations affect so-called dimensional crossover identified in [Adami et al. 2019]. Such a phenomenon has two evidences: coexistence one and Sobolev inequalities appearence...
