Scientists are widely expected to present evidence on Tuesday that the most coveted prize in particle physics - the Higgs boson - has been glimpsed.
While the Higgs is crucial to our understanding of the Universe, it has never been observed by experiments.
At a seminar here in Geneva, teams will present a progress report in their hunt for the tiny particle at the Large Hadron Collider (LHC).
But the LHC has not recorded enough data to claim a formal discovery.
Finding the Higgs was a key goal for the $10bn (£6bn) particle smasher. The collider hosts two experiments - Atlas and CMS - that are searching for the particle independently.
There is intense excitement among physicists working at Cern, the Geneva-based organisation which operates the collider, over hints that the hunters have cornered their quarry.
"It is a fantastic time at the moment, you can feel people are enthusiastic," Dr Christoph Rembser, a senior scientist on the Atlas experiment, told BBC News. "It is really very lively."
