Two scientists who predicted the existence of the Higgs boson — the mysterious particle that explains why elementary matter has mass — are Thomson Reuters' top tips to win this year's Nobel Prize in physics.

Recognition for a discovery that made headlines worldwide will come as no surprise, but deciding who deserves the glory is a tricky matter for the prize committee, which will announce its winner or winners on Oct. 8.

The will of Alfred Nobel limits the prize to a maximum of three people. Yet, six scientists published relevant papers in 1964, and thousands more have worked to detect the Higgs at the CERN research center's giant particle-smasher near Geneva.
