Description

The Circum-Pan-Pacific Symposium on High Energy Spin Physics (PacificSPIN) series was originally established to promote research in hadronic spin physics, with a particular focus on the partonic spin structure of the nucleon. Over the years, its scientific scope has expanded to encompass intriguing topics of spin polarization phenomena in heavy-ion collisions. Symposia in this series were held in Hefei(2024), Miyazaki(2019), Taipei(2015), Ji'nan(2013), Cairns(2011), Yamagata(2009), Vancouver(2007), Tokyo(2005), Washington(2003), Beijing(2001), Wako(1999), and Kobe (1996). The symposium also serves as a platform to strengthen collaboration and communication among physicists from the Circum-Pan-Pacific region and beyond, while providing valuable opportunities for young researchers to present their work.

We are pleased to announce that the next symposium, PacificSpin 2026, will be hosted by the Institute of Physics, Academia Sinica, in Taipei, from October 27 to 30, 2026 (Tuesday–Friday).

Scientific programs:

  • Transverse and longitudinal spin structure of the nucleon
  • Polarized parton distribution functions and fragmentation functions
  • Transverse momentum dependent distributions
  • Generalized parton distributions and form factors
  • Spin polarization in heavy ion collisions
  • Spin structure of the nucleon in Lattice QCD and effective QCD models
  • Future facilities and experiments

Important deadlines:

  • Registration / Abstract submission open: March 1
  • Abstract deadline: June 15
  • Notification for contributed talks: June 19
  • Visa and travel permit application: July 20
  • Registration deadline: October 15
