Goran Senjanović was a Croatian theoretical physicist known for seminal work in particle physics, neutrino mass, and left–right symmetry in extensions of the Standard Model. He made influential contributions to grand unified theory, seesaw mechanism, and baryogenesis research, and held positions at major institutions including CERN, Brookhaven National Laboratory, and the University of Zagreb. His work engaged with topics central to experiments at facilities such as the Large Hadron Collider, the Super-Kamiokande detector, and neutrino oscillation observatories.
Born in Zagreb in 1936, Senjanović studied physics in the former Kingdom of Yugoslavia and later in Socialist Federal Republic of Yugoslavia institutions, completing degrees at the University of Zagreb and graduate work connected with the University of Belgrade. During his formative years he interacted with physicists associated with the CERN and the postwar European revival of theoretical physics communities influenced by figures from Princeton University, Institute for Advanced Study, and the Fermi National Accelerator Laboratory. His education coincided with developments such as the formulation of the Standard Model, the rise of quantum field theory, and discussions on parity violation following the Wu experiment.
Senjanović held academic posts at the University of Zagreb and research appointments at international laboratories including CERN, Brookhaven National Laboratory, and collaborations with groups at Fermilab and the Max Planck Institute for Physics. He served as a senior scientist at the Institute of Physics, Zagreb and participated in joint projects with teams from the University of Milan, University of Oxford, Harvard University, and MIT. His visiting positions allowed close collaboration with theorists linked to SLAC National Accelerator Laboratory, Caltech, and the University of California, Berkeley while contributing to conferences organized by International Centre for Theoretical Physics and the European Physical Society.
Senjanović is best known for advancing the seesaw mechanism for neutrino mass generation in the context of left–right symmetric model frameworks, building on ideas connected to Yukawa coupling structures and Majorana fermion formulations. He worked on combinations of left–right symmetry, parity restoration, and implications for neutrinoless double beta decay experiments such as GERDA and EXO. His papers influenced theoretical proposals for probing lepton number violation at colliders like the Large Hadron Collider and in precision probes at Super-Kamiokande and SNO. Senjanović also contributed to discussions on grand unified theory scenarios tied to SO(10) and SU(5), and to mechanisms for baryogenesis via leptogenesis with colleagues working on connections to CP violation and electroweak symmetry breaking. He collaborated and exchanged ideas with notable physicists associated with Steven Weinberg, Abdus Salam, Sheldon Glashow, and Murray Gell-Mann school lines, and his work was cited in contexts involving theoretical analyses used by experimental collaborations at CERN experiments ATLAS and CMS. His legacy includes influential review articles and mentorship of researchers who joined faculties at institutions like the University of Chicago, Princeton University, and École Normale Supérieure.
Throughout his career Senjanović received recognition from national and international bodies including Croatian scientific academies and physics societies linked to the European Physical Society and the American Physical Society. He was honored by his home institutions such as the University of Zagreb and the Institute of Physics, Zagreb and acknowledged in symposiums alongside laureates of the Nobel Prize in Physics, recipients of the Dirac Medal, and awardees of the Wolf Prize in Physics. His work was highlighted at conferences organized by the International Union of Pure and Applied Physics and in commemorative volumes alongside contributors to neutrino physics and particle theory.
Senjanović lived primarily in Zagreb and maintained scientific ties across Europe and North America, fostering collaborations with researchers from Croatia, Serbia, Italy, France, United States, and United Kingdom. He passed away in 2017 in Zagreb, leaving a body of work that continues to influence ongoing experimental programs at CERN, Super-Kamiokande, and neutrino observatories worldwide.
