Higgs Boson

Yesterday was a  big day for physics. A new particle was discovered, a boson, at the energy 126GeV, with every indication it is probably the much sought after Higgs, one of the last pieces of the widely experimentally confirmed Standard Model of Particle physics yet to be observed.

Here’s a video offering a decent explanation why this matters:


And here’s a collection of tweets from live-blogging physicists, all of whom I recommend you follow.

    another suggestion from the particle physicists–let’s drive around honking horns, waving flags #eurocup #lhccup

    Okay, the sleepy felis Klein says it’s time for me to go back to bed. ‘But *which* Higgs?’ questions are for later. http://pic.twitter.com/wJTGqyQq

    Peter Higgs looking totally overwhelmed, elated and emotional. #LHC

    Higgs decaying to 2 photons 🙂 Looks very good… #CERN

    Making an exit: MT @tomscott At end of #higgs announcement, one of CERN team will nonchalantly say “oh, one more thing”, then teleport away.

    a weighted Higgs to gamma-gamma plot. Very nice bump over a lot of background as expected.I would call this a money plot.

    #ICHEP2012 #Higgs seminar @CERN: It’s impressive how billions of events can be distilled into a handful. Lot’s of smart sieving.

    “It was the last month of running that did it!” 5 sigma and applause. #Higgs

    Wed, Jul 04 2012 00:38:49
  12. ProfBrianCox
    And combined – 5 sigma. Round of applause. That’s a discovery of a Higgs – like particle at CMS. They thank LHC for the data!

    Nice – slide of the day. RT @astroengine Incandela says: “that’s pretty significant.” Bump screenshot: http://twitpic.com/a3pblc

    Last week’s “let’s pretend we’re constitutional scholars” on Twitter was fun, but tomorrow’s stab at “quantum theoretician” will be awesome.

    5 sigma is the usual particle physics threshold for discovery. It roughly means that you’re 99.9999% sure

    Beautiful collision images with two photons in the CMS detector: https://cdsweb.cern.ch/record/1459459/ #Higgs #ICHEP2012 Check these out!

    On a side note – when was your twitter stream this loaded with science, let alone particle physics? WIN!

    Wed, Jul 04 2012 00:44:51
  18. TaraShears
    To remind you – we need to test all these channels to see if we’re seeing a Standard Model Higgs or not.

  19. BadAstronomer
    When they combine all the results, they get a 4.9 sigma (~99.9999% certainty) that a decay energy seen at 125 GeV is real. #Higgs

    Wed, Jul 04 2012 00:49:20

    CMS final slide: we observe a boson at 125 GeV. Very nice. Very conservative statement. <3 science.

  21. TaraShears
    And wow. The first 7 twitter trending items are higgs-related…

    These colours really make this hard for me to look at… but yay, ATLAS time! #ICHEP2012 http://pic.twitter.com/YyFmfv2K

    #Higgs On reflection, I think I’d have been disappointed if Fabiola Gianotti hadn’t used comic sans.

    Still thinking about the CMS signal. You know, this is just the start. We are starting to unfold the universe that little bit more.

    CERN ATLAS & CMS combined press release: “new particle, at the level of 5 sigma, in the mass region around 126 GeV” http://press.web.cern.ch/press/PressReleases/Releases2012/PR17.12E.html

    Joe shows some properties of the new object. A new boson! Compatible with Higgs so far. Can’t wait to hear the next talk! @CMSexperiment

    Big question: Will the CERN press conference set for July 4 announce discovery of the Higgs particle or just give more tentative evidence?

    Sun, Jul 01 2012 07:26:15
  30. bgreene
    The five living physicists who discovered the Higgs idea have been invited to the CERN announcement, suggesting Wednesday’s news may be big.
