CERN July 4 Seminar

Summary from CMS by Joe Incandela:

We have observed a new boson with a mass of 125.3 ± 0.6 GeV at 4.9 σ significance !

Summary (excerpt) from ATLAS by Fabiola Gianotti:

We observe an excess of events at m_H ~ 126.5 GeV with local significance  5.0 sigma

Remarks from the CERN Director General Rolf Heuer:

“As a laymen I would now say I think we have it. Do you agree?”

Global effort -> Global success

Results today only possible do to extraordinary performance of accelerators – experiments –  Grid computing

Observation of a new particle consistent with a Higgs boson (but which one… ?)

Historic Milestone but only the beginning

Global implications for the future

Michel Spiro (President of CERN Council):

“If I may say so it is another giant leap for mankind.”

Chris Llewellyn Smith (former DG):

“I really am amazed that we can use these luminosities.”

Francois Englert:

“I am extraordinary impressed by what you have done.”

Peter Higgs:

“it is an incredible thing that it has happened in my lifetime.”

Gerald Guralnik:

“It is wonderful to be at a physics event where there is applause like there is at at football game.”

Rolf Heuer:

“Everybody that was involved in the project can be proud of this day. Enjoy it.”

  • This is great! Well, Detective “Higgsy Callahan”, AKA “Dirty Higgsy”, has been on the trail of this perpicle for years and had a few things to say about the search:

    Making sure the perpicles couldn’t get away:

    Higgsy: We’re not just going to let you walk out of here.
    Particles: Who’s “we”, sucker?
    Higgsy: ATLAS, CMS and me.

    As the trail got warmer, he thought it was chancy:

    “I know what you’re thinking: “Did we find five sigma, or only four?” Well, to tell you the truth, in all this excitement, I’ve kinda lost track myself. But being this is the LHC, the most powerful collider in the world, and would blow your mind clean off, you’ve got to ask yourself one question: “Do I feel lucky?” Well do ya, punk?”

    And as he closed in for the “arrest”, Dirty Higgsy said:

    “Go ahead, make my day!”

    Well, it did – today is the day! Congratulations!
