The Capra meeting is an annual workshop on the topic of radiation reaction in general relativity. The primary focus of these workshops is the development of self-force techniques to model extreme mass ratio inspirals and further our understanding of the two-body problem in General Relativity. This is done in synergy with other well known modeling techniques such as post-Newtonian theory and numerical relativity. The canonical example of an extreme mass-ratio Inspiral (EMRI) is the inspiral of a stellar-mass compact object into a supermassive black hole. Gravitational waves from these systems are a promising target for the future space-based detector LISA, which is currently scheduled to launch in 2032 by the European Space Agency with NASA. The study of radiation reaction and self force is not limited to EMRIs, and a range of topics and applications to other areas of gravitational physics have been discussed at past Capra meetings; an example is the scattering of massive particles, which is currently of active interest. The format of the meeting will be an amalgamation of short contributed talks, (organized) discussion sessions and a daily invited review talk. Given the current pandemic, the conference will take place online. Following the Capra tradition, there will be no registration fee.

An approximate schedule for the meeting is as follows:

At Capra, we provide equal opportunities regardless of gender, age, race, disability, ethnic origin, religion, sexual orientation, socio-economic status, civil status, or family status.  We urge all those with an interest in research on self-force and extreme mass-ratio inspirals to register for this meeting and submit an abstract for a presentation. Past and current attendees should encourage a broad spectrum of their colleagues to apply.



Territorial Land Acknowledgement

Perimeter Institute acknowledges that it is situated on the traditional territory of the Anishinaabe, Haudenosaunee, and Neutral peoples.

Perimeter Institute is located on the Haldimand Tract. After the American Revolution, the tract was granted by the British to the Six Nations of the Grand River and the Mississaugas of the Credit First Nation as compensation for their role in the war and for the loss of their traditional lands in upstate New York. Of the 950,000 acres granted to the Haudenosaunee, less than 5 percent remains Six Nations land. Only 6,100 acres remain Mississaugas of the Credit land.

We thank the Anishinaabe, Haudenosaunee, and Neutral peoples for hosting us on their land.
