A Brief History and Outlook of Hadronic Physics in Indonesia

Hadronic physics has gradually emerged as one of the growing research frontiers in Indonesia, driven by efforts to better understand the properties of the strong interaction and the internal structure of hadrons from the fundamental principles of Quantum Chromodynamics. In the last few decades, Indonesian researchers have made significant contributions to developing various theoretical and phenomenological aspects of hadrons. In addition, on the experimental side, Indonesian scientists have participated in hadron experiment facilities overseas, such as the ALICE collaboration at CERN, which has strengthened the scientific activities and networks and has supported the training of young Indonesian researchers. In the present paper, we review Indonesian scientists’ contributions to hadronic physics, highlight ongoing research directions in both experimental and theoretical, and outline strategies for future development toward integration into the international hadronic physics community.

💡 Research Summary

The paper provides a comprehensive historical review of hadronic physics in Indonesia, tracing its evolution from a handful of pioneering individuals in the 1970s to a mature, internationally connected research community today. The authors first outline the “Pioneering Stage” (1970‑2000), highlighting early contributors such as M. Barmawi and Tjia May On, who introduced Regge‑theory and quark‑model studies after training at institutions like the University of Chicago and ICTP. Although many of these early scholars later shifted to material physics, their work laid the conceptual groundwork for later Indonesian efforts.

The next period, “Early Millennium” (2000‑2010), saw the establishment of the first substantial hadronic physics group at Universitas Indonesia (UI) under the mentorship of Darmadi Kusno, his student Yohanes Surya, and Terry Mart. This generation produced a unitary relativistic resonance model for πN scattering, explored electromagnetic kaon production on nucleons, and investigated non‑relativistic and relativistic mean‑field descriptions of super‑heavy nuclei and neutron stars. Their training was heavily supported by German DAAD scholarships, ICTP fellowships, and collaborations with European laboratories (Mainz, Frankfurt).

Experimental participation entered a new phase when former UI students such as Suhary Sumowidagdo and Alvin Kiswandhi joined LHC experiments (CMS, ALICE) and contributed to quark‑gluon plasma (QGP) studies, heavy‑ion collisions, and hadron spectroscopy. This marked Indonesia’s first sustained involvement in large‑scale high‑energy physics collaborations.

In the “Recent Developments” (2010‑present) the community embraced cutting‑edge theoretical tools: holographic QCD, AdS/CFT correspondence, and multi‑gluon scattering calculations. Notable works include Zain ul Abidin’s holographic computation of nucleon gravitational form factors, Ardian N. Atmadja’s AdS/CFT analysis of QGP transport, and Parada T.P. Hutauruk’s studies of in‑medium meson modifications relevant for neutrino interactions in neutron stars. Researchers now hold positions at the Asia‑Pacific Center for Theoretical Physics (APCTP), RIKEN, and the newly formed BRIN (formerly LIPI), fostering cross‑institutional projects that blend theory and experiment.

Institutionally, the paper documents the transition from LIPI to the National Research and Innovation Agency (BRIN), the formalization of a Ph.D. program in theoretical physics at UI (first graduate in 2019), and the expansion of hadronic groups at ITB, UGM, and IPB. International networks—ALICE, PHENIX, STAR, J‑PARC, BESIII—are emphasized as essential for training, data sharing, and joint publications.

Looking forward, the authors propose several strategic actions: (1) integrate Indonesian groups into upcoming facilities such as the Electron‑Ion Collider (EIC) and FAIR to study medium‑energy hadron structure; (2) develop high‑performance computing clusters for lattice QCD and machine‑learning‑driven data analysis; (3) broaden experimental collaborations beyond ALICE to include STAR, BESIII, and future heavy‑ion programs; (4) strengthen domestic university‑research institute linkages, promote gender and youth participation, and establish joint graduate programs with overseas universities.

In summary, Indonesian hadronic physics has progressed from isolated theoretical efforts to a vibrant, multi‑institutional field that actively contributes to global QCD research through both sophisticated theoretical modeling and participation in world‑leading experiments. The paper concludes that with continued investment in infrastructure, international partnerships, and human‑resource development, Indonesia is well positioned to become a significant player in the worldwide hadronic physics community.
