TORSION — Tests Of Relativity with Spin InteractiONs
The Instituto de Ciencias Nucleares (UNAM) will host this workshop in Mexico City on May 18–20, 2026.
Workshop Focus
This workshop aims to bring together theorists working on non-Riemannian extensions of General Relativity, particularly those working on models that incorporate spacetime torsion, and experimentalists with the capabilities to probe spin-dependent interactions. These two communities do not usually interact, and as a result gravitational effects that are sensitive to spin have remained largely untested.
The program will feature in-person talks on recent developments and future prospects, with ample time for discussion.
Organization
This workshop is jointly organized by the National Autonomous University of Mexico (UNAM) and the Indiana University Center for Spacetime Symmetries (IUCSS) through the Indiana University Gateway at UNAM.
Topics
- Torsion-related phenomenology
- Experimental searches for spin-dependent interactions
- Gravitational theories with torsion and exact solutions
