The Very Nearly Right Theory of Flavor

Nima Arkani-Hamed, Carolina Figueiredo, Lawrence J. Hall +1

A striking empirical observation about the CKM matrix is that the angles of the unitarity triangle are very close to , simple fractions of that…

Combinatorics of the Cosmohedron

Federico Ardila-Mantilla, Nima Arkani-Hamed, Carolina Figueiredo +1

The cosmohedron was recently proposed as a polytope underlying the cosmological wavefunction for theory. Its faces were conjectured to be in bijection with Matryos…

Generating the fermion mass hierarchy at the TeV scale

Nima Arkani-Hamed, Carolina Figueiredo, Lawrence J. Hall +1

We propose a class of theories to generate quark and lepton mass matrices where the scale of new physics is at the TeV scale, without inducing the large flavor and CP violating pro…

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…
