Half-ladder partial waves for all with applications to string theory

Jeffrey V. Backus

Given any four-point scattering amplitude, the partial wave expansion resolves its residues into contributions from individual spin- internal particles, where each coefficient i…

New Recursions for the Canonical Scalar-Scaffolded Yang-Mills Amplitude

Jeffrey V. Backus

The recently-developed "scalar-scaffolding" formulation of gluon amplitudes casts the Yang-Mills (YM) amplitude as a well-defined Laurent series expansion in scalar variables, vali…

Surface Gauge Invariance, Soft Limits and the Transmutation of Gluons into Scalars

Jeffrey V. Backus, Carolina Figueiredo

Over the past year, the "scalar-scaffolding" formalism has revealed a number of new features of gluon amplitudes. In this paper, we leverage these developments to study two distinc…

Emergence of Unitarity and Locality from Hidden Zeros at One-Loop Order

Jeffrey V. Backus, Laurentiu Rodina

Recent investigations into the geometric structure of scattering amplitudes have revealed the surprising existence of "hidden zeros": secret kinematic loci where tree-level amplitu…

Toward extracting from without binning

Jeffrey V. Backus, Marat Freytsis, Yuval Grossman +2

transitions are known to provide theoretically clean information about the CKM angle , with the most precise available methods exploiting the cascade decay of…
