SYM Description of PP-wave String Interactions: Singlet Sector and Arbitrary Impurities [PDF]

, 2003
We study string interactions among string states with arbitrary impurities in the Type IIB plane wave background using string field theory. We reproduce all string amplitudes from gauge theory by computing matrix elements of the dilatation operator in a ...

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.

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.

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.

Tr(F 3) supersymmetric form factors and maximal transcendentality. Part I. N $$ \mathcal{N} $$ = 4 super Yang-Mills

Journal of High Energy Physics, 2018
In the large top-mass limit, Higgs plus multi-gluon amplitudes in QCD can be computed using an effective field theory. This approach turns the computation of such amplitudes into that of form factors of operators of increasing classical dimension.

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.

Minimal String Theory [PDF]

, 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 ...

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

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.
