California Amplitudes Meeting
October 10-12, 2016
UCLA Physics & Astronomy Department
This is the second in a series for meetings for researchers in California interested in scattering amplitudes. The first was held at UC Davis.
The focus is on recent topic in scattering amplitudes, including mathematical aspects of positive Grassmannian and Amplituhedron, non-planar on-shell diagrams, ratio functions in N=4 SYM, symbols and the basis of hexagon functions, multi-loop integrated amplitude, the CHY formula, BCJ duality, double-copy relations and applications to effective field theories.
Organizers: Zvi Bern (UCLA), Clifford Cheung (Caltech), Lance Dixon (SLAC), Jaroslav Trnka (UC Davis).
Meeting schedule
Monday October 10 - Wednesday October 12, 2016
Coffee starts at 11 AM on Monday. No talks in the morning to give people extra time to arrive.

The Bhaumik Institute congratulates Professor Thomas Dumitrescu on his naming as a 2026 Laureate of the New Horizons in Physics Prize for his discovery and development of the theory of “generalized symmetries” in quantum field theory.
The International Congress of Basic Science recently awarded Zvi Bern and Mikhail Solon a 2026 Best Paper Frontiers of Science Award for their paper, together with their collaborators, "

Congratulations to Prof. Eric D'Hoker and former graduate student Justin Kaidi on the publication of their book, "Modular Forms and String Theory," by Cambridge University Press.
