The Future of String Theory [PDF]
Unification of Fundamental Interactions, 1987 Prophesy is just for fun. The more useful purpose of the exercise is to identify important issues and to stimulate thought about where they stand and how they might be resolved. The subject areas that are fair game include all of particle physics and cosmology.

Theory Assessment and Final Theory Claim in String Theory [PDF]
, 2011 String theory has by now maintained a highly influential position in high energy physics for more than a quarter of a century. The present article analyses the reasons for the considerable trust exponents of string theory have in their theory even though

Holographic RG flows in $$N=4$$ N=4 SCFTs from half-maximal gauged supergravity
European Physical Journal C: Particles and Fields, 2018 We study four-dimensional $$N=4$$ N=4 gauged supergravity coupled to six vector multiplets with semisimple gauge groups $$SO(4)\times SO(4)$$ SO(4)×SO(4) , $$SO(3,1)\times SO(3,1)$$ SO(3,1)×SO(3,1) and $$SO(4)\times SO(3,1)$$ SO(4)×SO(3,1) . All of these

Counting dyons in N=4 string theory [PDF]
, 1996 We present a microscopic index formula for the degeneracy of dyons in four-dimensional N=4 string theory. This counting formula is manifestly symmetric under the duality group, and its asymptotic growth reproduces the macroscopic Bekenstein-Hawking ...

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 ...

Sequestering in string theory [PDF]
Journal of High Energy Physics, 2007 We study sequestering, a prerequisite for flavor-blind supersymmetry breaking in several high-scale mediation mechanisms, in compactifications of type IIB string theory. We find that although sequestering is typically absent in unwarped backgrounds, strongly warped compactifications do readily sequester.

Forty Years of String Theory: Reflecting on the Foundations [PDF]
, 2013 The history of string theory started around 1970 when Nambu, Nielsen, and Susskind realized that Veneziano’s 1968 dual model, devised to explain the particle spectrum of the strong interactions, actually describes the properties of quantum mechanical ...

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

Supersymmetrical string theories
Physics Letters B, 1982 A supersymmetrical light-cone-gauge string action is presented. It provides a basis for understanding the previously-studied supersymmetrical dual string theory as well as two new closed-string theories that have extended supersymmetry in ten dimensions, corresponding to N = 8 supersymmetry in four dimensions.

String theory and string Newton–Cartan geometry* [PDF]
Journal of Physics A: Mathematical and Theoretical, 2019 Abstract Nonrelativistic string theory is described by a sigma model with a relativistic worldsheet and a nonrelativistic target spacetime geometry, that is called string Newton–Cartan geometry. In this paper we obtain string Newton–Cartan geometry as a limit of the Riemannian geometry of general relativity with a fluxless two-form ...
