Scrutinizing supergravity models through neutrino telescopes. [PDF]
Physical Review D, Particles and fields, 1993 Galactic halo neutralinos ([chi]) captured by the Sun or Earth produce high-energy neutrinos as end products of various annihilation modes. These neutrinos can travel from the Sun or Earth cores to the neighborhood of underground detectors ( neutrino ...

General F-theory models with tuned (SU(3) × SU(2) × U(1))/ℤ6 symmetry
Journal of High Energy Physics, 2020 We construct a general form for an F-theory Weierstrass model over a general base giving a 6D or 4D supergravity theory with gauge group (SU(3) × SU(2) × U(1))/ℤ6 and generic associated matter, which includes the matter content of the standard model. The

Non-Lorentzian IIB supergravity from a polynomial realization of SL(2, ℝ)
Journal of High Energy Physics, 2023 We derive the action and symmetries of the bosonic sector of non-Lorentzian IIB supergravity by taking the non-relativistic string limit. We find that the bosonic field content is extended by a Lagrange multiplier that implements a restriction on the ...

Supergravity, AdS/CFT Correspondence and Matrix Models [PDF]
, 1999 The recent developments towards the possible non-perturbative formulation of string/M theory using supersymmetric Yang-Mills matrix models (SYMs) are discussed.

New constraints on supergravity models from b-->s gamma. [PDF]
Physical Review D, Particles and fields, 1994 We perform a detailed study of the constraints from [ital b][r arrow][ital s][gamma] on a large class of supergravity models, including generic four-parameter supergravity models, the minimal SU(5) supergravity model, and SU(5)[times]U(1) supergravity ...

Holomorphic field theories and higher algebra
Bulletin of the London Mathematical Society, Volume 57, Issue 10, Page 2903-2974, October 2025.Abstract Aimed at complex geometers and representation theorists, this survey explores higher dimensional analogs of the rich interplay between Riemann surfaces, Virasoro and Kac‐Moody Lie algebras, and conformal blocks. We introduce a panoply of examples from physics — field theories that are holomorphic in nature, such as holomorphic Chern‐Simons ...

Probing supergravity models with indirect experimental signatures [PDF]
Physical Review D, 1995 We explore the one-loop electroweak radiative corrections in the context of the traditional minimal $SU(5)$ and the string-inspired $SU(5)\times U(1)$ supergravity models by calculating explicitly vacuum-polarization and vertex-correction contributions to the $ _1$ and $ _b$ parameters.

De sitter magnetic black hole dipole with a supersymmetric horizon
Journal of High Energy Physics, 2021 We find a new non BPS solution in N = 2 D = 4 gauged supergravity coupled to U(1) gauge fields and matter. It consists in a closed universe with two extremal black holes of equal size, surrounding two singularities.

Higher Curvature Supergravity, Supersymmetry Breaking and Inflation
, 2014 In these lectures, after a short introduction to cosmology, we discuss the supergravity embedding of higher curvature models of inflation. The supergravity description of such models is presented for the two different formulations of minimal supergravity.
