Detectors in Nonrelativistic Conformal Field Theories
Cyuan-Han Chang, Subham Dutta Chowdhury, Ian Moult +1
Correlations in asymptotic fluxes provide one of the primary experimental means of studying physical systems. In the context of relativistic QFT, the formalization of such experime…
Nonrelativistic Conformal Collider Physics of Multiparticle Point Production
Cyuan-Han Chang, Subham Dutta Chowdhury, Ian Moult +1
We define detector operators in the nonrelativistic conformal field theory describing fermions at unitarity. We reduce the problem of computing the momentum distribution and correl…
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…
Bootstrapping the 3d Ising Stress Tensor
Cyuan-Han Chang, Vasiliy Dommes, Rajeev S. Erramilli +6
We compute observables of the critical 3d Ising model to high precision by applying the numerical conformal bootstrap to mixed correlators of the leading scalar operators and $…
Spinning dispersive CFT sum rules and bulk scattering
Cyuan-Han Chang, Yakov Landau, David Simmons-Duffin
We use commutativity of null-integrated operators on the same null plane to construct dispersive CFT sum rules for spinning operators. The contribution of heavy blocks to these sum…
Scalar Modular Bootstrap and Zeros of the Riemann Zeta Function
Nathan Benjamin, Cyuan-Han Chang
Using the technology of harmonic analysis, we derive a crossing equation that acts only on the scalar primary operators of any two-dimensional conformal field theory with …
Three-point energy correlators and the celestial block expansion
Cyuan-Han Chang, David Simmons-Duffin
We study the three-point energy correlator (EEEC), defined as a matrix element of a product of three energy detectors at different locations on the celestial sphere. Lorentz symmet…
Transverse spin in the light-ray OPE
Cyuan-Han Chang, Murat Kologlu, Petr Kravchuk +2
We study a product of null-integrated local operators and on the same null plane in a CFT. Such null-integrated operators transform like primaries i…
A Subleading Power Operator Basis for the Scalar Quark Current
Cyuan-Han Chang, Iain W. Stewart, Gherardo Vita
Factorization theorems play a crucial role in our understanding of the strong interaction. For collider processes they are typically formulated at leading power and much less is kn…
