A topological invariant in the context of the loop representation of the massive Kalb-Ramond-Klein-Gordon model
E. Iñiguez, M. Freire, L. Leal +1
We employ the Dirac procedure to quantize the self-dual massive Kalb-Ramond-Klein-Gordon model in dimensional spacetimes. The canonical fields are expressed in terms of -s…
A Gravitino Distance Conjecture
Alberto Castellano, Anamaría Font, Alvaro Herraez +1
We conjecture that in a consistent supergravity theory with non-vanishing gravitino mass, the limit is at infinite distance. In particular one can write $M_{…
Spinning solutions for the bosonic M2-brane with fluxes
Pedro D. Alvarez, Pedro García, Maria Pilar Garcia del Moral +2
In this work we obtain classical solutions of the bosonic sector of the supermembrane theory with two-form fluxes associated to a quantized constant background. This theo…
Exploring the landscape of CHL strings on T^d
Anamaria Font, Bernardo Fraiman, Mariana Graña +2
Compactifications of the heterotic string on special T^d/Z_2 orbifolds realize a landscape of string models with 16 supercharges and a gauge group on the left-moving sector of redu…
Solitons and instantons in vacuum stability: physical phenomena
J. A. Gonzalez, A Bellorin, L E Guerrero +3
In a previous paper [JCAP06, 033 (2018)] we have proved that it is possible to have a stable false vacuum in a potential that is unbounded from below. In this paper we discuss the…
Exploring the landscape of heterotic strings on T^d
Anamaría Font, Bernardo Fraiman, Mariana Graña +2
Compactifications of the heterotic string on T^d are the simplest, yet rich enough playgrounds to uncover swampland ideas: the U(1)^{d+16} left-moving gauge symmetry gets enhanced…
On scale separation in type II AdS flux vacua
Anamaría Font, Alvaro Herráez, Luis E. Ibáñez
We study the separation of AdS and Kaluza-Klein (KK) scales in type II 4d AdS orientifold vacua. We first address this problem in toroidal/orbifold type IIA vacua with metric fluxe…
The Swampland Distance Conjecture and Towers of Tensionless Branes
Anamaría Font, Alvaro Herráez, Luis E. Ibáñez
The Swampland Distance Conjecture states that at infinite distance in the scalar moduli space an infinite tower of particles become exponentially massless. We study this issue in t…
M2-branes on a constant flux background
M. P. Garcia del Moral, C. Las Heras, P. Leon +2
We describe a compactified Supermembrane, or M2-brane, with 2-form fluxes generated by constant three-forms that are turned on a 2-torus of the target space . We com…
Fate of the true-vacuum bubbles
J. A. González, A. Bellorín, Mónica A. García-Ñustes +4
We investigate the bounce solutions in vacuum decay problems. We show that it is possible to have a stable false vacuum in a potential that is unbounded from below.
Non-Geometric Vacua of the Heterotic String and Little String Theories
Anamaría Font, Christoph Mayrhofer
We study a class of 6d non-geometric vacua of the heterotic string which can be understood as fibrations of genus-two curves over…
On global aspects of duality invariant theories: M2-brane vs DFT
G. Abellan, C. Las Heras, M. P. Garcia del Moral +2
Supermembrane compactified on a target space is globally described by the inequivalent classes of torus bundles over torus. These torus bundles have monodromy in $S…
A monoidal representation for linearized gravity
Ernesto Contreras, Cayetano Di Bartolo, Lorenzo Leal
We propose an alternative representation for linear quantum gravity. It is based on the use of a structure that bears some resemblance to the Abelian loop representation used in el…
Heterotic T-fects, 6D SCFTs, and F-Theory
Anamaría Font, Iñaki García-Etxebarria, Dieter Lust +2
We study the six-dimensional SCFTs living on defects of non-geometric heterotic backgrounds (T-fects) preserving a subgroup of . These config…
The Flux-Scaling Scenario: De Sitter Uplift and Axion Inflation
Ralph Blumenhagen, Cesar Damian, Anamaria Font +2
Non-geometric flux-scaling vacua provide promising starting points to realize axion monodromy inflation via the F-term scalar potential. We show that these vacua can be uplifted to…
Aspects of the T-duality construction for the Supermembrane theory
M. P. Garcia del Moral, J. M. Pena, A. Restuccia
In this note we explicitly show how the generalization of the T-duality symmetry of the supermembrane theory compactified in M9xT2 can be reduced to a parabolic subgroup of SL(2,Z)…
Geometric Representation of Interacting Non-Relativistic Open Strings using Extended Objects
P. J. Arias, N. Bolivar, E. Fuenmayor +1
Non-relativistic charged open strings coupled with Abelian gauge fields are quantized in a geometric representation that generalizes the Loop Representation. The model consists of…
Up-type quark masses in SU(5) F-theory models
Anamaría Font, Fernando Marchesano, Diego Regalado +1
F-theory SU(5) unification has been proposed as a scenario where the mass of the top quark is naturally large, as opposed to type II SU(5) models. We analyze this claim from the vi…
A Comment on Continuous Spin Representations of the Poincaré Group and Perturbative String Theory
Anamaria Font, Fernando Quevedo, Stefan Theisen
We make a simple observation that the massless continuous spin representations of the Poincaré group are not present in perturbative string theory constructions. This represents on…
T-duality Invariance of the Supermembrane
M. P. Garcia del Moral, J. M. Pena, A. Restuccia
We show that the supermembrane theory compactified on a torus is invariant under T-duality. There are two different topological sectors of the compactified supermembrane (M2) class…
Non-perturbative effects and Yukawa hierarchies in F-theory SU(5) Unification
Anamaría Font, Luis E. Ibáñez, Fernando Marchesano +1
Local SU(5) F-theory models lead naturally to Yukawa couplings for the third generation of quarks and leptons, but inducing Yukawas for the lighter generations has proven elusive.…
Mimetic discretization of the Abelian Chern-Simons theory and link invariants
Cayetano Di Bartolo, Javier Grau, Lorenzo Leal
A mimetic discretization of the Abelian Chern-Simons theory is presented. The study relies on the formulation of a theory of differential forms in the lattice, including a consiste…
Supermembrane origin of type II gauged supergravities in 9D
M. P. Garcia del Moral, J. M. Pena, A. Restuccia
The M-theory origin of the IIB gauged supergravities in nine dimensions, classified according to the inequivalent classes of monodromy, is shown to exactly corresponds to the globa…
Master actions for linearized massive gravity models in 3-D
Pio J. Arias, Adel Khoudeir, J. Stephany
We present a unified analysis of the self-dual, second order, topologically massive and the recently introduced fourth order models of massive gravity in 3D. We show that there is…
