Accurate bootstrap bounds from optimal interpolation
Cyuan-Han Chang, Vasiliy Dommes, Petr Kravchuk +2
We develop new methods for approximating conformal blocks as positive functions times polynomials, with applications to the numerical bootstrap. We argue that to obtain accurate bo…
Seeing through the confinement screen: DGLAP/BFKL mixing and light-ray matching in QCD
Cyuan-Han Chang, Hao Chen, David Simmons-Duffin +1
We argue that collider observables such as hadron number flux can be matched onto a linear combination of detectors/light-ray operators in perturbative QCD. The spectrum of detecto…
Properties of scalar partition functions of 2d CFTs
Nathan Benjamin, Cyuan-Han Chang, A. Liam Fitzpatrick +1
We study the spectrum of scalar primary operators in any two-dimensional conformal field theory. We show that the scalars alone obey a nontrivial crossing equation. This extends pr…
Graviton loops and negativity
Cyuan-Han Chang, Julio Parra-Martinez
We revisit dispersive bounds on Wilson coefficients of scalar effective field theories (EFT) coupled to gravity in various spacetime dimensions, by computing the contributions from…
