Topology and Wilson lines: global aspects of the double copy
Journal of High Energy Physics, 2020 The Kerr-Schild double copy relates exact solutions of gauge and gravity theories. In all previous examples, the gravity solution is associated with an abelian-like gauge theory object, which linearises the Yang-Mills equations.

String Backgrounds in String Geometry [PDF]
Int.J.Mod.Phys.A 35 (2020) 27, 2050176, 2020 String geometry theory is a candidate of the non-perturbative formulation of string theory. In order to determine the string vacuum, we need to clarify how string backgrounds are described in string geometry theory. In this paper, we show that the string backgrounds are embedded in configurations of the fields of a string geometry model. Especially, we

Dual conformal invariance for form factors
Journal of High Energy Physics, 2019 Form factors of the stress-tensor multiplet operator in N = 4 $$ \mathcal{N}=4 $$ supersymmetric Yang-Mills reveal surprisingly simple structures similar to those appearing in scattering amplitudes.

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 ...

Fermionic pole-skipping in holography
Journal of High Energy Physics, 2020 We examine thermal Green’s functions of fermionic operators in quantum field theories with gravity duals. The calculations are performed on the gravity side using ingoing Eddington-Finkelstein coordinates.

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

Advances in String Theory in Curved Backgrounds: A Synthesis Report [PDF]
Int.J.Mod.Phys.A18:2011-2024,2003, 2003 A synthetic report of the advances in the study of classical and quantum string dynamics in curved backgrounds is provided, namely: the new feature of multistring solutions; the effect of a cosmological constant and of spacial curvature on classical and quantum strings; classical splitting of fundamental strings;the general string evolution in constant

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

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.

Exactly Soluble Dynamics of (p,q) String Near Macroscopic Fundamental Strings [PDF]
JHEP0412:008,2004, 2004 We study dynamics of Type IIB bound-state of a Dirichlet string and n fundamental strings in the background of N fundamental strings. Because of supergravity potential, the bound-state string is pulled to the background fundamental strings, whose motion is described by open string rolling radion field.
