Anticipation is building in the run-up to presentations of the best-yet evidence for - or against - the existence of the Higgs boson.
The famed particle is a missing link in current theories of physics, used to explain how everything gains its mass.
Rumours have been swirling about the findings for weeks, ahead of the announcement on Tuesday afternoon.
It is likely to yield only tantalising hints, as the teams do not have enough data to claim a formal discovery.
However, most physicists concede that not finding the Higgs boson is as exciting a prospect as finding it in the place where existing theory predicts it should be.
"If we wouldn't find it it would be even - in a way - more exciting, but you know, both ways, it's a win-win situation," said Stefan Soldner-Rembold, a particle physicist from the University of Manchester
