Pavel Fileviez Perez is a theoretical physicist known for work on extensions of the Standard Model, baryon number violation, and predictions for proton decay within Grand Unified Theories. His research bridges model building, phenomenology, and connections to experimental searches at facilities such as the Large Hadron Collider, Super-Kamiokande, and proposed detectors like DUNE (experiment). He has held positions in academic institutions and contributed to collaborations spanning CERN, Fermilab, and national funding agencies.

Early life and education

Born in Paraguay, he completed early studies that led to doctoral work in particle physics. He received his Ph.D. under the supervision of advisors connected to research groups active at IFIC, CERN, and Latin American physics communities. His formative training involved graduate research addressing topics related to Grand Unified Theory, Supersymmetry, and symmetry breaking patterns studied in contexts like SO(10) and SU(5) model building. During his graduate and postdoctoral years he interacted with researchers affiliated with Harvard University, Massachusetts Institute of Technology, University of California, Berkeley, and regional centers such as Instituto Balseiro.

Academic career and positions

He has held postdoctoral and faculty appointments at institutions with strong particle physics programs, including research visits to CERN, collaborations with groups at Fermilab and SLAC National Accelerator Laboratory, and faculty roles at universities engaged in theoretical and experimental outreach. His teaching and mentoring have linked students to projects at KEK, TRIUMF, and national laboratories in Europe and the Americas. He has participated in committees of organizations such as the American Physical Society, the European Organization for Nuclear Research, and regional consortia that coordinate efforts in high-energy physics and astroparticle searches.

Research contributions and notable results

His research contributions focus on baryon number violation, model-building for neutrino masses, and collider signatures of new gauge bosons and scalar sectors. He proposed mechanisms in which gauge symmetries embedded in SO(10), SU(5), or left–right symmetric frameworks lead to distinctive signals for proton decay searchable by Super-Kamiokande, Hyper-Kamiokande, and SNO+. He analyzed connections between baryon number violation and leptogenesis scenarios linked to seesaw mechanism realizations, making predictions testable at LHC, ILC, and future colliders like FCC. His work explored the phenomenology of new gauge bosons (Z' models) and scalar fields that can produce resonant production at ATLAS (detector), CMS experiment, and low-energy experiments such as NA62 experiment.

Notable results include quantitative estimates of proton lifetime in variants of SU(5) and SO(10) that revise expectations for decay channels like p → π0 e+ and p → K+ ν̄, influencing target sensitivities for Super-Kamiokande and DUNE (experiment), and proposing experimental strategies to disentangle competing decay modes. He also developed models tying gauge coupling unification to intermediate scales that could produce observable signals in flavor experiments such as Belle II and LHCb. His papers often connect cosmological constraints from Big Bang nucleosynthesis and Cosmic Microwave Background studies by teams like Planck Collaboration to particle model parameters.

Awards and honors

He has received recognitions from national and international bodies for contributions to theoretical particle physics and for building scientific collaborations between Latin America and Europe. His honors include invitations to present at conferences organized by ICTP, SUSY Conference, and workshops of the Particle Data Group. He has been awarded fellowships and grants from national science agencies collaborating with institutions such as CONICET, FAPESP, and research programs supported by the European Research Council.
