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 ...

TeV-Scale strings

, 2014
This article discusses the status of string physics where the string tension is around the TeV scale. The article covers model building basics for perturbative strings, based on D-brane configurations. The effective low energy physics description of such

Weak Scale Superstrings [PDF]

, 1996
Recent developments in string duality suggest that the string scale may not be irrevocably tied to the Planck scale. Two explicit but unrealistic examples are described where the ratio of the string scale to the Planck scale is arbitrarily small ...

A First Glimpse of String Theory in the Sky? [PDF]

, 2004
We propose a new method for identifying new physics imprints on present observational data in cosmology whereby signatures of string theory are clearly distinguished from imprints of possible features on the inflaton potential.

String Landscape and the Standard Model of Particle Physics

, 2007
In this paper we describe ideas about the string landscape, and how to relate it to the physics of the Standard Model of particle physics. First, we give a short status report about heterotic string compactifications. Then we focus on the statistics of D-

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 ...

Noncommutative Field Theories and (Super)String Field Theories

, 2001
In this lecture notes we explain and discuss some ideas concerning noncommutative geometry in general, as well as noncommutative field theories and string field theories.

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.

D3-brane loop amplitudes from M5-brane tree amplitudes

Journal of High Energy Physics, 2020
We study loop corrections to scattering amplitudes in the world-volume theory of a probe D3-brane, which is described by the supersymmetric Dirac-Born-Infeld theory.
