From Schwinger to Wightman: all conformal 3-point functions in momentum space
Marc Gillioz
All conformal correlation functions of 3 scalar primary operators are constructed in an axiomatic way, relying only on conformal symmetry and causality. The construction makes use…
Conformal partial waves in momentum space
Marc Gillioz
The decomposition of 4-point correlation functions into conformal partial waves is a central tool in the study of conformal field theory. We compute these partial waves for scalar…
A Scattering Amplitude in Conformal Field Theory
Marc Gillioz, Marco Meineri, Joao Penedones
We define form factors and scattering amplitudes in Conformal Field Theory as the coefficient of the singularity of the Fourier transform of time-ordered correlation functions, as…
Convergent Momentum-Space OPE and Bootstrap Equations in Conformal Field Theory
Marc Gillioz, Xiaochuan Lu, Markus A. Luty +1
General principles of quantum field theory imply that there exists an operator product expansion (OPE) for Wightman functions in Minkowski momentum space that converges for arbitra…
Conformal 3-point functions and the Lorentzian OPE in momentum space
Marc Gillioz
In conformal field theory in Minkowski momentum space, the 3-point correlation functions of local operators are completely fixed by symmetry. Using Ward identities together with th…
Momentum-space conformal blocks on the light cone
Marc Gillioz
We study the momentum-space 4-point correlation function of identical scalar operators in conformal field theory. Working specifically with null momenta, we show that its imaginary…
