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…
