Two-dimensional SCFTs from matter-coupled $$7D~N=2$$ 7DN=2 gauged supergravity
European Physical Journal C: Particles and Fields, 2019 We study supersymmetric $$AdS_3\times M^4$$ AdS3×M4 solutions of $$N=2$$ N=2 gauged supergravity in seven dimensions coupled to three vector multiplets with $$SO(4)\sim SO(3)\times SO(3)$$ SO(4)∼SO(3)×SO(3) gauge group and $$M^4$$ M4 being a four ...

, 1996 Recent developments in string duality suggest that the string scale may not be irrevocably tied to the Planck scale. Two explicit but unrealistic examples are described where the ratio of the string scale to the Planck scale is arbitrarily small ...

Supersymmetric domain walls in 7D maximal gauged supergravity
European Physical Journal C: Particles and Fields, 2019 We give a large class of supersymmetric domain walls in maximal seven-dimensional gauged supergravity with various types of gauge groups. Gaugings are described by components of the embedding tensor transforming in representations $$\mathbf {15}$$ 15 and

Reductions of exceptional field theories
Journal of High Energy Physics, 2020 Double Field Theory (DFT) and Exceptional Field Theory (EFT), collectively called ExFTs, have proven to be a remarkably powerful new framework for string and M-theory.

Quarter-BPS states, multi-symmetric functions and set partitions
Journal of High Energy Physics, 2021 We give a construction of general holomorphic quarter BPS operators in N $$ \mathcal{N} $$ = 4 SYM at weak coupling with U(N) gauge group at finite N. The construction employs the Möbius inversion formula for set partitions, applied to multi-symmetric ...

Zero-norm states and stringy symmetries
, 2005 We identify spacetime symmetry charges of 26D open bosonic string theory from an infinite number of zero-norm states (ZNS) with arbitrary high spin in the old covariant first quantized string spectrum.

String Landscape and the Standard Model of Particle Physics
, 2007 In this paper we describe ideas about the string landscape, and how to relate it to the physics of the Standard Model of particle physics. First, we give a short status report about heterotic string compactifications. Then we focus on the statistics of D-

Supersymmetric RG flows and Janus from type II orbifold compactification
European Physical Journal C: Particles and Fields, 2017 We study holographic RG flow solutions within four-dimensional $$N=4$$ N = 4 gauged supergravity obtained from type IIA and IIB string theories compactified on $$T^6/\mathbb {Z}_2\times \mathbb {Z}_2$$ T 6 / Z 2 × Z 2 orbifold with gauge, geometric and ...

A First Glimpse of String Theory in the Sky? [PDF]
, 2004 We propose a new method for identifying new physics imprints on present observational data in cosmology whereby signatures of string theory are clearly distinguished from imprints of possible features on the inflaton potential.
