Physicist Carl Hagen, one of the original scientists to develop the theories on the Higgs mechanism and Higgs boson, applauded the apparent success of CERN scientists in finding evidence of the elusive subatomic particle. Hagen was in attendance at CERN’s research facilities near Geneva, Switzerland, on
July 4, when researchers announced the discovery of a new particle that is “consistent with the Higgs boson.”
The announcement was based on the findings of two separate experiments—CMS and Atlas—being conducted at CERN’s Large Hadron Collider (LHC).
“The work is very impressive and is a truly remarkable achievement,” said Hagen. “Yet that is not to say that it is the long-sought boson. Its spin has yet to be determined, for example.”
The Higgs boson, which makes it possible for particles to have mass, is the only particle predicted by the Standard Model of particle physics that has not yet been observed.
His 1964 article, “Global Conservation Laws and Massless Particles,” cowritten by Gerald Guralnik and Thomas Kibble, was named one of the milestone papers in the history of Physical Review Letters.
Hagen traveled to Switzerland for the historic announcement. He described the presentation at CERN as unusual and extraordinary, with the talks “interspersed with bouts of prolonged applause.”
The Higgs boson is believed to be responsible for other particles having mass. It is the only particle predicted by the Standard Model of particle physics that has not yet been observed.
