The Very Nearly Right Theory of Flavor
Nima Arkani-Hamed, Carolina Figueiredo, Lawrence J. Hall +1
The paper proposes a simple class of Yukawa matrix textures with nine non‑zero entries that naturally link the observed CKM unitarity‑triangle angles to multiples of π/8, offering…
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 Matryo…
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…
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 associa…
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…
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…
