Q: Exact duplicate(closed) questions and automatic link insertion

ArgusThe current procedure for a closed as exact duplicate automatically insert the link to the question in duplicate. This link is denoted as "Possible Duplicate" should this say "Exact Duplicate" as the question was peer reviewed and the decision to close was reached.

@experimentX Yeah, you missed it by a couple hours
 
So basically, the announcement will be of the form "a particle exists with high conficence at 125 GeV"?
 
Yeah. In fact we actually already know that such a particle exists with some confidence, as of last December; the confidence should be higher now.
 
I mean, no indication that its the Higgs?
 
@Manishearth We can't be sure it's the Higgs yet.
The way they will be checking this is examining the relative decay rates into various types of particles, and checking whether those agree with standard model predictions
As of December, they mostly agreed, but not quite... but the confidence of that result wasn't very high
But now we should have better information
I wrote a blog post about this earlier today which has some of this information
 
6:46 AM
Ah, thanks for the link :)
 
7:04 AM
@DavidZaslavsky Started :D
Damn, too laggy :(
Meh, I'll just hope for them to post a final video of the presentation. WHenever it pauses due to lag, it doesn't start off from where it stopped :\
 
:(
Well, most of it is not new stuff anyway
 
Yep.
 
Right now they're just going over how CMS works
 
7:19 AM
Yeah, I figured...
 
7:33 AM
OK, so CMS is seeing a just over 4σ significance in the γγ channel
...and 3.2σ in the ZZ channel
which combine to 5.0σ (commence clapping :-P)
 
Great!
 
7:49 AM
OK, so this is interesting.. they found basically nothing in the H→ττ channel. That could lean in favor of this not being the standard model Higgs...
overall significance is 4.9σ from CMS alone
 
8:01 AM
The Higgs decays into everything with mass, amirite?
 
8:18 AM
@Manishearth Yeah, but most of the branching ratios are negligible
 
Kk.. By H-->tautau, do you mean higgs decaying into two taus? How is that possible? (I can understand H-->tauantitau)
Or is that just a label for something?
 
It is tau + antitau, but you can't really type a bar over the τ in most fonts so we just write ττ
 
8:40 AM
ATLAS has found 5σ independently as well
 
9:36 AM
Great :)
PARTAY!
 
@Manishearth I'd never say no to a party :-)
except now, because I have to eat dinner (!!!) and go to sleep
I do have another blog post up about the results from the conference, in case anyone is interested

Q: "Develop method by which to see electronic display in sun-light", help me to make this engineering question into physics

hhhI would like to be able to see a display such as computer screen or mobile phone display in sunlight. This question is more about engineering so have to refine this somehow. It consists of novel ideas such as: [?] get a display that I can use in sun -light [optics, mechanics, other?] develop g...

@DavidZaslavsky That's what you get for not using LaTeX for everything like God an Don Knuth intended.
 
The really interesting thing from the announcements is that both experiments are notably over the expectations in the gamma--gamma channel. There is still plenty of room for that to be statistics, but it looks very interesting right now. We could have an almost-but-not-quite Standard Model Higgs, which would be a lot of fun.
But in generally the collider guys tend to ignore the matterness of particles when convenient because at those energies there is no functional difference.

@DavidZaslavsky I appreciate you collecting the data in one place like a blog for me to read.
 
11:46 PM
@Kortuk Thanks, good to know it was useful :-)
 
@DavidZaslavsky I really need to take more physics and get myself up to speed.
@DavidZaslavsky But most everything you said was logical to me, I unlike my wife, have never taken a class where something like a Feynman diagram was used.
 
Well, it was 5 AM and I was too tired to put in anything technical
too technical, anyway
