Gravitational Waves meet Amplitudes in the Southern Hemisphere

August 14 – September 1, 2023

The central theme of the program will be the application of particle physics methods to the calculation of processes relevant to gravitational-wave phenomenology.

We intend to bring together both experts and younger theorists from three distinct communities:

– Classical General Relativity, including both analytic and numerical approaches;

– Effective Field Theories;

– Scattering Amplitudes.

We also want to bring theorists into contact with observers and analysis specialists from LIGO-Virgo-KAGRA.

We intend to have one talk a day, with lots of time available for informal discussions and collaboration. The building hosting the program is brand new with comfortable discussion areas, right next to the intended hotel in the tourist center of São Paulo. We hope to have fifteen to twenty people in residence each week.

This activity will be preceded by the School on Modern Amplitude Methods for Gauge and Gravity Theories. Selected students attending the school have the option of remaining as observers.

There is no registration fee.
