    I think its something to do with the Higgs being a field that breaks down and gives mass to other particles as it decays.

    I think the Higgis (or whatever particle they've found) decays very easily/quickly (as it's massive) it interacts with other particles to give them mass.
    I must be right, heyyo agrees :)

    Mass energy equivalence.

    e=mc^2 and all that. The GeV is unit of energy and hence is a standard measured of mass in particle physics. IIRC 1eV is 1.6*10^-19 Joules or something like that - so not very much.

    There ya go - wiki has it.
    http://en.wikipedia.org/wiki/Electronvolt
    So apparently I weigh 4.2 x 10^28 GeV, which is 3 x 10^26 Higgs bosons.

    I am fucking massive.

    So when do we learn to manipulate these higgs fields and create anti grav cars?

    We should at least have hoverboards in time for 2015.

    This is the best "forum level" explanation I've seen so far.

    The Official t-shirt to commemorate the finding of the Higgs boson by our very own spindizzy.

    Order now to avoid disappointment, they're selling fast.

    Ha ha ha! Excellent!

    I'm slowly recovering and catching up on emails and stuff, but I'll try to read the thread at some point... I am a very, very happy man right now, the utter exhaustion not-withstanding.

    Edit: And just as I write that I find I need to go back to work to fix something for another presentation. Obviously it's urgent and obviously it must be done tonight. Argh! :-(

    Maybe I won't be too responsive until tomorrow. Sorry!

    Good link that, cheers

    I think, in light of views that it's not where they expected to find it, and it's not entirely what they were expecting, it should be officially named "The Higgsish Boson".
  • Deleted user 5 July 2012 18:56:51
    Or maybe "The Bosony Boson" would be much more accurate.
    Given that it's a Boson.

    ? It's at the lower mass end, which was considered more likely and has (from what we can tell at this early stage) exactly the couplings (properties, if you like) predicted for the Standard Model Higgs (except the gamma gamma channel is a bit enhanced).

    Not sure exactly what you mean by blips, but the data used is from a couple of weeks ago. There's nothing more recent, and the stuff we see now builds on the first hints we saw last year.

    Did you guys see how few Higgs we saw? It's something like (for ATLAS) 13 collisions out of a trillion. 13. CMS is at a similar level, so it's ~25 Higgs for a couple of trillion collisions.

    I don't get it? Why is it a blow for Atheists?

    Also, does this mean we can time travel yet? Got some shit to rectify a few years back.

    I had gamma gamma chanel once. A strong course of anti biotics saw it off in the end. Hang in there spindizzy.
  • Deleted user 5 July 2012 19:39:50
    Oh sorry - I thought they expected it to be heavier.

    Some bloke on the radio early said 'gamma gamma something something' or 'something something gamma gamma' (or was it 'gabba gabba hey'?). I have no idea what it was, but it sounded important!

    Some other boffin on the radio yesterday said something about it having slightly unexpected properties, but didn't say exactly what was unexpected.
  • Deleted user 5 July 2012 19:42:51
    Oh! Spindizzy said "Higgs"! It's the real deal confirmed!

    Uh, so the Higgs Boson is just some mahoosive (meaning mass, rather than size) particle that interacts strongly with the higgs field just like other particles interact with the higgs field. Suddenly I'm less impressed they found it.

    Read this was being compared to the moon landing, still have no idea what the hell it is all about though :/

    The moon is like a tiny planet that orbits us. Managing to set foot on an alien surface was a major step for humanity.

    What do you mean you dont know what it's about.

    It helps confirm our theory of the Universe (or, some of it) as we have now actually seen something that was predicted to exist.
  • Deleted user 6 July 2012 07:00:19
    Oh well, thanks for clearing that up then... :/

    I would've thought the particle responsible for making things massive would have been of more interest to mowgli.

    I just mean you dont have to be into physics or mathematics (oh which im awful at)
    to at least think understanding the universe is kinda cool. I dont know the science behind it, but im not sure I really need to.

    It's more that finding it (which, ignoring super-cautious scientist-speak, we have) proves that the extremely elegant, beautiful theory that predicted it, is correct. It's a massive, massive (ho ho!) deal. The question now is - is there just one? If we find more, then maybe super symmetry is also correct, which might help us understand Dark Matter.

    I love my job.

    In terms of science, I think this is much bigger (up there with observing the bending of starlight around the sun, which confirmed Einstein's Relativity). In terms of technical achievement, I guess they're comparable (building the LHC is a colossal achievement - I'm still staggered we did it).

    I still love my job.
