About the speaker:
Henriette Elwang is Arthur F. Thurnau Professor and Oskar Klein Collegiate Professor of Physics at University of Michigan. Her research interests are in scattering amplitudes in connection with particle physics, general relativity and string theory. She has received her PhD from University of California Santa Barbara and has held postdoctoral appointments at MIT and IAS Princeton. She has also co-authored a popular textbook on scattering amplitudes called "Scattering Amplitudes in Gauge Theories and Gravity".
Abstract:
I will describe the constraints of maximal supersymmetry on super Yang-Mills EFT tree amplitudes and show how a simple parity constraint implies that the 6-point SUSY Ward identities can only be
solved when the Wilson coefficients in the 4-point amplitude obey novel non-linear constraints. When these are combined with positivity, the allowed values of the 4-point Wilson coefficients are restricted
to lie in a small region shrinking (as more constraints are included) around the values for the Veneziano amplitude.
The UNIVERSE+ Online Seminar Series is designed to foster dialogue and collaboration among project partners and those interested in positive geometry.
