Howard Haber

Howard Haber Howard Haber is an American theoretical physicist known for contributions to particle physics, especially studies of the Higgs boson, supersymmetry, and beyond-Standard-Model phenomenology. He has held faculty and research positions at major institutions and collaborated with experimental programs at facilities such as CERN, Fermilab, and SLAC National Accelerator Laboratory. Haber's work bridges theoretical model building, collider phenomenology, and interpretation of results from the Large Hadron Collider and predecessor experiments.

Early life and education

Haber was educated in the United States and completed undergraduate and graduate work in physics at institutions including University of California, Berkeley and University of California, Santa Cruz, where he studied under advisors tied to research programs associated with Stanford Linear Accelerator Center and the Lawrence Berkeley National Laboratory. During his doctoral and postdoctoral training he engaged with theoretical groups focused on electroweak symmetry breaking, supersymmetric models, and phenomenology relevant to experiments at CERN and Fermilab, interacting with researchers from Harvard University, Massachusetts Institute of Technology, and California Institute of Technology.

Academic career and positions

Haber has served on the faculty at University of California, Santa Cruz and held visiting or collaborative appointments at national laboratories and international centers including SLAC National Accelerator Laboratory, CERN, and Fermilab. He has participated in advisory roles for collaborations at the Large Hadron Collider, worked with detector and analysis teams from ATLAS and CMS, and contributed to theoretical working groups connected to the Particle Data Group and the American Physical Society. Haber has supervised graduate students and postdoctoral researchers who have gone on to positions at institutions such as Princeton University, University of Chicago, Columbia University, and Imperial College London.

Research contributions and notable work

Haber's research focuses on theoretical frameworks for electroweak-scale physics, including studies of the Higgs boson sector, extended Higgs models, and supersymmetry phenomenology. He has authored influential analyses of the Minimal Supersymmetric Standard Model, radiative corrections to Higgs masses, and strategies for Higgs and superpartner searches at colliders like the Large Hadron Collider and the Tevatron. His collaborations produced widely cited reviews and papers addressing CP violation in extended Higgs sectors, the decoupling limit in two-Higgs-doublet models, and collider signatures relevant to experiments at ATLAS, CMS, and future facilities such as the International Linear Collider and proposed Future Circular Collider. Haber has contributed to precision studies connecting theoretical models to observables measured by the Particle Data Group, DESY, KEK, and experiment-driven theory efforts at SLAC. He has coauthored computational tools and analytic results used by phenomenologists and experimentalists at CERN and national laboratories.

Awards and honors

Haber's work has been recognized by professional societies and research institutions; he has received honors and invitations to lead topical workshops and summer schools sponsored by organizations such as the American Physical Society, Institute of Physics, and national laboratories including SLAC National Accelerator Laboratory and Fermilab. He has been invited to deliver plenary and invited talks at conferences including the International Conference on High Energy Physics, the Rencontres de Moriond, and meetings organized by the European Physical Society.
