Splitting Regions and Shrinking Islands from Higher Point Constraints
Justin Berman, Henriette Elvang, Carolina Figueiredo
We study constraints from higher-point amplitudes on scattering in the context of effective field theory (EFT) using the perturbative numerical S-matrix bootstrap. Specif…
Correlator Polytopes
Carolina Figueiredo, Francisco Vazão
Recently, "cosmohedra" have been introduced as polytopes underlying the cosmological wavefunction for conformally coupled Tr() theory in FRW cosmologies, generalizing associah…
Open String Amplitudes: Singularities, Asymptotics, and New Representations
Nima Arkani-Hamed, Carolina Figueiredo, Grant N. Remmen
Open string amplitudes at tree level have been studied for over fifty years, but there is no known analytic form for general -point amplitudes, and their conventional representa…
Surface Kinematics and "The" Yang-Mills Integrand
Nima Arkani-Hamed, Qu Cao, Jin Dong +2
It has been a long-standing challenge to define a canonical loop integrand for non-supersymmetric gluon scattering amplitudes in the planar limit. Naive integrands are inflicted wi…
All-order splits and multi-soft limits for particle and string amplitudes
Nima Arkani-Hamed, Carolina Figueiredo
The most important aspects of scattering amplitudes have long been thought to be associated with their poles. But recently a very different sort of "split" factorizations for a wid…
Circles and Triangles, the NLSM and Tr()
Nima Arkani-Hamed, Carolina Figueiredo
A surprising connection has recently been made between the amplitudes for Tr() theory and the non-linear sigma model (NLSM). A simple shift of kinematic variables naturally su…
Tropical Amplitudes For Colored Lagrangians
Nima Arkani-Hamed, Carolina Figueiredo, Hadleigh Frost +1
Recently a new formulation for scattering amplitudes in Tr() theory has been given based on simple combinatorial ideas in the space of kinematic data. This allows all-loop int…
Scalar-Scaffolded Gluons and the Combinatorial Origins of Yang-Mills Theory
Nima Arkani-Hamed, Qu Cao, Jin Dong +2
We present a new formulation for Yang-Mills scattering amplitudes in any number of dimensions and at any loop order, based on the same combinatorial and binary-geometric ideas in k…
Hidden zeros for particle/string amplitudes and the unity of colored scalars, pions and gluons
Nima Arkani-Hamed, Qu Cao, Jin Dong +2
Recent years have seen the emergence of a new understanding of scattering amplitudes in the simplest theory of colored scalar particles - the Tr theory - based on combinator…
Multiparticle Factorization and the Rigidity of String Theory
Nima Arkani-Hamed, Clifford Cheung, Carolina Figueiredo +1
Is string theory uniquely determined by self-consistency? Causality and unitarity seemingly permit a multitude of putative deformations, at least at the level of two-to-two scatter…
