François Englert (1932 – 2026)
CERN announces the passing of Nobel laureate François Englert, a pivotal figure behind the Higgs mechanism, who theorized how fundamental particles acquire mass. His groundbreaking work, alongside Robert Brout and Peter Higgs, laid the foundation for the Standard Model of particle physics. This news highlights the enduring legacy of a giant in theoretical physics and the profound impact of his contributions on our understanding of the universe.
The Lowdown
CERN has announced the passing of theoretical physicist François Englert, a Nobel laureate celebrated for his seminal contributions to the understanding of how elementary particles acquire mass. Englert, who passed away on June 18th at the age of 93, revolutionized particle physics with his theoretical work, which was eventually confirmed by experimental discoveries at CERN.
- Englert, collaborating with Robert Brout, demonstrated that fundamental particles could acquire mass through interaction with a ubiquitous fundamental field.
- Independently, British physicist Peter Higgs proposed the same mechanism, adding the concept of an associated particle, later known as the Higgs boson.
- Their theories, building on Yoichiro Nambu's work and adapting spontaneous symmetry breaking into quantum field theory, resolved a major problem in electroweak theory where vector bosons were predicted to be massless.
- The existence of the Brout-Englert-Higgs field was experimentally proven in 2012 with the discovery of the Higgs boson by the ATLAS and CMS experiments at the Large Hadron Collider (LHC).
- For their groundbreaking work, François Englert and Peter Higgs were jointly awarded the Nobel Prize in Physics in 2013.
- Englert had a distinguished career at the Université libre de Bruxelles (ULB), where he co-founded a research group that explored diverse areas, including strong interactions, general relativity, and cosmology, and remained engaged with theoretical physics as a professor emeritus.
Englert's profound insights not only earned him the highest accolades but also continue to shape the frontier of particle physics, inspiring ongoing research into the universe's most fundamental mysteries and paving the way for potential discoveries beyond the Standard Model.
