Supercurrents in N = 1 Minimal Supergravity in the Superconformal Formalism
We discuss the Einstein tensor, the supercurrent and their conservation laws of old and new minimal formulations of supergravity in the superconformal approach. The variation of the action with respect to the ...

Open AccessPatient-Reported Outcomes in an Observational Cohort of HIV-1-Infected Adults on Darunavir/Cobicistat-Based Regimens: Beyond Viral Suppression
This prospective, multicenter, non-interventional cohort study enrolling human immunodeficiency virus (HIV)-1-infected, virally suppressed adult outpatients in Italy aimed to describe results obtained from pat...

Open AccessBimetric, conformal supergravity and its superstring embedding
We discuss the connection between Weyl2 supergravity and superstrings and further discuss holography between 4-dimensional, ...

Open AccessSpin-four \( \mathcal{N}=7 \) W-supergravity: S-fold and double copy construction
In the present investigation we consider the possibility of having new massive, higher spin W-supergravity theories, which do not exist as four-dimensional perturbative models. These theories are based on a do...

Open AccessThe supercurrent and Einstein equations in the superconformal formulation
We give a new expression for the supercurrent and its conservation in curved N ...

Open AccessLinear versus non-linear supersymmetry, in general
We study superconformal and supergravity models with constrained superfields. The underlying version of such models with all unconstrained superfields and linearly realized supersymmetry is presented here, in ...

Article
Open Accessℛ2 supergravity
We formulate R2 pure supergravity as a scale invariant theory built only in terms of superfields describing the geometry of curved superspace. The standard supergravity duals are obtained in both “old” and “new” ...

A genotype–phenotype correlation in Sicilian patients with GJB2 biallelic mutations
The aim of this work was to study the genotype distribution of Sicilian patients with biallelic GJB2 mutations; to correlate genotype classes and/or specific mutations of GJB2 gene (35delG–non-35delG) with audiol...

Article
Open AccessCosmology with nilpotent superfields
We discuss N=1 supergravity inflationary models based on two chiral multi-plets, the inflaton and the goldstino superfield. Using superconformal methods for these models, we propose to replace the unconstraine...

Open AccessParietal subdural empyema as complication of acute odontogenic sinusitis: a case report
To date intracranial complication caused by tooth extractions are extremely rare. In particular parietal subdural empyema of odontogenic origin has not been described. A literature review is presented here to ...

Open AccessOn the topology of the inflaton field in minimal supergravity models
We consider global issues in minimal supergravity models where a single field inflaton potential emerges. In a particular case we reproduce the Starobinsky model and its description dual to a certain formulati...

Open AccessOn the supersymmetric completion of R + R 2 gravity and cosmology
We revisit and clarify the supersymmetric versions of R + R 2 gravity, in view of the renewed interest to these models in cosmology. We emphasize that the content of the dual standard supe...

Open AccessDualities near the horizon
In 4-dimensional supergravity theories, covariant under symplectic electricmagnetic duality rotations, a significant role is played by the symplectic matrix ...

Open AccessMulti-centered first order formalism
We propose a first order formalism for multi-centered black holes with flat three-dimensional base-space, within the stu model of N = 2, D = 4 ungauged MaxwellEinstein supergravity. This provides a unified descri...

Open AccessConstitutive relations and Schrödinger’s formulation of nonlinear electromagnetic theories
We present a systematic study of nonlinear and higher derivatives extensions of electromagnetism. We clarify when action functionals S[F] can be explicitly obtained from arbitrary (not necessarily self-dual) nonl...

Open Accessd-geometries revisited
We analyze some properties of the four dimensional supergravity theories which originate from five dimensions upon reduction. They generalize to N > 2 extended supersymmetries the d-geometries with cubic prepoten...

Open AccessSuper-Ehlers in any dimension
We classify the enhanced helicity symmetry of the Ehlers group to extended supergravity theories in any dimension. The vanishing character of the pseudo-Riemannian cosets occurring in this analysis is explaine...

Open AccessDegeneration of groups of type E 7 and minimal coupling in supergravity
We study properties of D = 4 \( \mathcal{N} \geqslant {2} \) extended supergravities (and related compactifications of superstr...
