, 2004 We summarize recent progress in the understanding of minimal string theory, focusing on the worldsheet description of physical operators and D-branes. We review how a geometric interpretation of minimal string theory emerges naturally from the study of ...

Form factor recursion relations at loop level
Journal of High Energy Physics, 2019 We introduce a prescription to define form factor integrands at loop level in planar N = 4 $$ \mathcal{N}=4 $$ supersymmetric Yang-Mills theory. This relies on a periodic kinematic configuration that has been instrumental to describe form factors at ...

Semiclassical Quantization of Effective String Theory and Regge Trajectories [PDF]
, 2002 We begin with an effective string theory for long distance QCD, and evaluate the semiclassical expansion of this theory about a classical rotating string solution, taking into account the the dynamics of the boundary of the string.

Standard Model EFTs via on-shell methods
Journal of High Energy Physics, 2021 We present the Standard Model Effective Field Theories (SMEFT) from purely on-shell arguments. Starting from few basics assumptions such as Poincaré invariance and locality, we classify all the renormalisable and non-renormalisable interactions at lowest

Twisted compactifications of 6D field theories from maximal 7D gauged supergravity
European Physical Journal C: Particles and Fields, 2020 We study supersymmetric $$AdS_n\times \Sigma ^{7-n}$$ AdSn×Σ7-n , $$n=2,3,4,5$$ n=2,3,4,5 solutions in seven-dimensional maximal gauged supergravity with $$CSO(p,q,5-p-q)$$ CSO(p,q,5-p-q) and $$CSO(p,q,4-p-q)$$ CSO(p,q,4-p-q) gauge groups.

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

Oriented Open-Closed String Theory Revisited [PDF]
, 1997 String theory on D-brane backgrounds is open-closed string theory. Given the relevance of this fact, we give details and elaborate upon our earlier construction of oriented open-closed string field theory.

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 ...

Matrix string interactions [PDF]
, 1998 String configurations have been identified in compactified Matrix theory at vanishing string coupling. We show how the interactions of these strings are determined by the Yang-Mills gauge field on the worldsheet.

Quasinormal modes of stringy black holes [PDF]
, 2001 String theory is a promising candidate for a fundamental quantum theory of all interactions including Einstein gravity. Some solutions in string theory can be interpreted as black holes. Using the semi-analytic method and WKB method,the quasinormal modes(
