Symmetry extension by condensation defects II: general dimensions and higher-groups
Matteo Bertolini, Lorenzo Di Pietro, Stefano C. Lanza +1
We discuss a class of symmetry structures in general spacetime dimension that arise when gauging symmetries in theories with a cubic 't Hooft anomaly. The anomaly mixes two Abelian…
Symmetry extension by condensation defects in five-dimensional gauge theories
Matteo Bertolini, Lorenzo Di Pietro, Stefano C. Lanza +2
We investigate the symmetry structure of five-dimensional Yang-Mills theories with gauge algebra. These theories feature intertwined 0-, 1-, and 2-form symmetrie…
Global symmetry-breaking and generalized theta-terms in Type IIB EFTs
Thomas W. Grimm, Stefano Lanza, Thomas van Vuren
A longstanding conjecture states that global symmetries should be absent in quantum gravity. By investigating large classes of Type IIB four-dimensional effective f…
Tameness, Strings, and the Distance Conjecture
Thomas W. Grimm, Stefano Lanza, Chongchuo Li
The Distance Conjecture states that an infinite tower of modes becomes exponentially light when approaching an infinite distance point in field space. We argue that the inherent pa…
Large Field Distances from EFT strings
Stefano Lanza, Fernando Marchesano, Luca Martucci +1
In any consistent effective field theory of quantum gravity limits of infinite field distance are expected to lead to the EFT breakdown due to the appearance of an infinite tower o…
Semiclassics of three-dimensional SCFTs from holography
Stefano Cremonesi, Stefano Lanza, Luca Martucci
We use holography to compute the large- effective field theory along the moduli space of vacua of an infinite class of three-dimensional SCFTs admitting a dual M…
The EFT stringy viewpoint on large distances
Stefano Lanza, Fernando Marchesano, Luca Martucci +1
We observe a direct relation between the existence of fundamental axionic strings, dubbed EFT strings, and infinite distance limits in 4d EFTs coupled to gravity. T…
de Sitter in non-supersymmetric string theories: no-go theorems and brane-worlds
Ivano Basile, Stefano Lanza
We study de Sitter configurations in ten-dimensional string models where supersymmetry is either absent or broken at the string scale. To this end, we derive expressions for the co…
Swampland Conjectures for Strings and Membranes
Stefano Lanza, Fernando Marchesano, Luca Martucci +1
Swampland criteria like the Weak Gravity Conjecture should not only apply to particles, but also to other lower-codimension charged objects in 4d EFTs like strings and membranes. H…
How , SYM domain walls look like
Igor Bandos, Stefano Lanza, Dmitri Sorokin
We review main features of the pure , SYM and its effective description by the Veneziano-Yankielowicz generalized sigma-model. We then indicate that the constru…
Exploring the Landscape of effective field theories
Stefano Lanza
In this thesis we provide new tools to determine and explore the Landscape of four-dimensional effective field theories originating from string and M-theory. The main aim is to int…
How many fluxes fit in an EFT?
Stefano Lanza, Fernando Marchesano, Luca Martucci +1
We extend the recent construction of 4d three-form Lagrangians by including the most general three-form multiplets necessary to reproduce any F-term potential in st…
Supermembranes and domain walls in , SYM
Igor Bandos, Stefano Lanza, Dmitri Sorokin
We construct a manifestly supersymmetric and kappa-symmetry invariant worldvolume action describing the coupling of a dynamical membrane to an , super-Y…
On the dynamical origin of parameters in Supersymmetry
Niccolò Cribiori, Stefano Lanza
We formulate global supersymmetric Lagrangians of self-interacting vector multiplets in terms of variant multiplets, whose non-propagating fields are replaced with…
Three-forms, dualities and membranes in four-dimensional supergravity
Igor Bandos, Fotis Farakos, Stefano Lanza +2
We consider four-dimensional supergravity models of a kind appearing in string flux compactifications. It has been recently shown that, by using double three-form m…
Three-forms, Supersymmetry and String Compactifications
Fotis Farakos, Stefano Lanza, Luca Martucci +1
We review a duality procedure that relates standard matter-coupled N=1 supergravity to dual formulations in which auxiliary fields are replaced by field-strengths of gauge three-fo…
Three-forms in Supergravity and Flux Compactifications
Fotis Farakos, Stefano Lanza, Luca Martucci +1
We present a duality procedure that relates conventional four-dimensional matter-coupled N=1 supergravities to dual formulations in which auxiliary fields are replaced by field-str…
