Journal of High Energy Physics, 2018 The study of form factors has many phenomenologically interesting applications, one of which is Higgs plus gluon amplitudes in QCD. Through effective field theory techniques these are related to form factors of various operators of increasing classical ...

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 ...

Double field theory and geometric quantisation
Journal of High Energy Physics, 2021 We examine various properties of double field theory and the doubled string sigma model in the context of geometric quantisation. In particular we look at T-duality as the symplectic transformation related to an alternative choice of polarisation in the ...

Temporal-gauge String Field with Open Strings [PDF]
Phys.Lett. B351 (1995) 439-444, 1994 A string field theory including open string fields is constructed in the temporal gauge. It consists of string interaction vertices similar to the light-cone gauge string field theory. A slight modification of the definition of the time coordinate is needed because of the existence of the open string end points.

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 ...

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 ...

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.

JHEP 0609:082,2006, 2005 We classify potential cosmic strings according to the topological charge measurable outside the string core. We conjecture that in string theory it is this charge that governs the stability of long strings. This would imply that the SO(32) heterotic string can have endpoints, but not the E_8 x E_8 heterotic string.

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

Cosmological Quantum String Vacua and String-String Duality [PDF]
Nucl.Phys.Proc.Suppl. 52A (1997) 344-346, 1996 Implications of string-string dualities to cosmological string vacua are discussed. Cosmological vacua of classical string theories comprise of disjoint classses mapped one another by scale-factor T-duality. Each classes are, however, afflicted with initial/final cosmological singularities.
