Landau Discriminants
Sebastian Mizera, Simon Telen
Scattering amplitudes in quantum field theories have intricate analytic properties as functions of the energies and momenta of the scattered particles. In perturbation theory, thei…
Crossing Symmetry in the Planar Limit
Sebastian Mizera
Crossing symmetry asserts that particles are indistinguishable from anti-particles traveling back in time. In quantum field theory, this statement translates to the long-standing c…
Bounds on Crossing Symmetry
Sebastian Mizera
Proposed in 1954 by Gell-Mann, Goldberger, and Thirring, crossing symmetry postulates that particles are indistinguishable from anti-particles traveling back in time. Its elusive p…
Coaction and double-copy properties of configuration-space integrals at genus zero
Ruth Britto, Sebastian Mizera, Carlos Rodriguez +1
We investigate configuration-space integrals over punctured Riemann spheres from the viewpoint of the motivic Galois coaction and double-copy structures generalizing the Kawai-Lewe…
