Michigan Interdisciplinary Meeting on Amplitudes: Bridges between Physics & Mathematics

24 Oct 2025, 09:20 → 26 Oct 2025, 15:00 US/Eastern

University of Michigan, Ann Arbor

October 24, 25, & 26, 2025

Description

This interdisciplinary conference will bring together theoretical physicists and mathematicians to explore recent interdisciplinary advancements in research on scattering amplitudes. Participants from both the physics and mathematics communities will bring a diverse range of perspectives to the field of amplitudes.

The conference is funded jointly by the Leinweber Institute for Theoretical Physics (LITP) and the Michigan Center for Applied and Interdisciplinary Mathematics (MCAIM).

Students from both the physics and mathematics communities are welcome to register and participate. Junior researchers are invited to participate in a "gong show" session of 5 minute talks on Saturday 10/25. 

There is no registration fee. Coffee and light refreshments will be provided.

Registration is now closed.
