Rolf is drawing the conclusions. He just asked the audience:

"I think we have it. Do you agree ?" And a roar of consensus fills the auditorium.

The slide says "The observation of a new particle consistent with a Higgs boson".

It is a historic milestone, but only the beginning.

A standing ovation follows. Then a connection with Melbourne, with the other auditorium applauding. Now questions in the CERN site ensuing.

Theorists take the stage, Higgs saying it is an extraordinary achievement for the lab, and that he is glad that it happened in his lifetime.

A very moving finale !
At CERN, the European Particle Physics Laboratory, the ATLAS and CMS experiments presented their latest results in the search for the Higgs particle. Both experiments see strong indications for the presence of a new particle in the mass region around 125-126 GeV and a 4.9-5 sigma signal.

When the results from the two experiments are combined, they should show a 5-sigma signal and be a discovery. If this is indeed a new particle, then it must be a boson and it would be the heaviest such particle ever found.

The Higgs boson has been discovered last year. There is no news today. It is merely the significance level that is a little higher now, but even a level of so called “five sigma” (don’t worry if you do not understand it, it is arbitrary anyway) does not prove anything.
The long and complicated journey to detect the Higgs boson might finally have reached its goal, said experimental physicists at the European Laboratory for Particle Physics, CERN, near Geneva - and they said it with a telltale bump on a slide.

The Higgs boson is the final building block that has been missing from the "Standard Model," which describes the structure of matter in the universe. The Higgs boson combines two forces of nature and shows that they are, in fact, different aspects of a more fundamental force. The particle is also responsible for the existence of mass in the elementary particles.

This is the second post of a series of blogs that I am writing this morning, July 4th, to describe the ongoing happenings at CERN, where at 9AM the Higgs boson Observation will be announced by the ATLAS and CMS collaborations.
