Nonrelativistic string theory and T-duality [PDF]

Journal of High Energy Physics, 2018
A bstractNonrelativistic string theory in flat spacetime is described by a two-dimensional quantum field theory with a nonrelativistic global symmetry acting on the worldsheet fields. Nonrelativistic string theory is unitary, ultraviolet complete and has

Tr(F 3) supersymmetric form factors and maximal transcendentality. Part II. 0 < N $$ \mathcal{N} $$ < 4 super Yang-Mills

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 ...

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.

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 ...

De Sitter vs Quintessence in String Theory [PDF]

Fortschritte der Physik, 2018
De Sitter solutions have been recently conjectured to be incompatible with quantum gravity. In this paper we critically assess the progress and challenges of different mechanisms to obtain de Sitter vacua in string compactifications and compare them to ...

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.

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.

SO(32) Spinors of Type I and Other Solitons on Brane-Antibrane Pair [PDF]

, 1998
We construct the SO(32) spinor state in weakly coupled type I string theory as a kink solution of the tachyon field on the D-string - anti-D-string pair and calculate its mass.

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.

Linear Dilatons, NS5-branes and Holography [PDF]

, 1998
We argue that vacua of string theory which asymptote at weak coupling to linear dilaton backgrounds are holographic. The full string theory in such vacua is ``dual'' to a theory without gravity in fewer dimensions.
