Description

The proton’s tensor charge, connected to internal quark transverse spin, is one of its fundamental properties. This quantity has garnered interest from various communities, being relevant for QCD phenomenology, ab initio studies (e.g., lattice QCD, Dyson-Schwinger), and low-energy beyond the Standard Model searches. In this talk I will review the current status of extractions of the proton’s tensor charge within QCD global analyses of transverse-spin sensitive data from various processes. I will also discuss agreements and tensions that exist between different approaches and outline future work that may help us to converge on the value of this critical quantity.
