Has the Higgs Boson Particle Been Discovered at Cern?

[mfb]

Searches for SUSY (=supersymmetry) particles are a big part of the physics analyses done with the ATLAS and CMS detectors.
So far, none were found. We'll see what happens in 2015 with the increased energy.

We hear people talking about the "party model" of the Higgs boson, but what made that particle so popular in the first place? In a technical question:What makes matter interact with the higgs in the first place?

We hear people talking about the "party model" of the Higgs boson, but what made that particle so popular in the first place?

According to Boston Globe:

The celebrity analogy, for instance, was first concocted in 1993 by David Miller, a physicist at University College London. Miller submitted it as one of the winning entries to a challenge posed by UK Science Minister William Waldegrave: On one sheet of paper, explain what the Higgs boson is and why it’s important to find it.

In a technical question:What makes matter interact with the higgs in the first place?

There is no known deeper reason why things interact. We just observe those interactione and can describe them with formulas.

Additionally to mfb's P#183 and why the matter interacts with Higgs:
They interact because they are allowed by the current symmetries... If some interaction terms are allowed by your theory's symmetries, then you have to take them into account. If these interactions happen not to exist, one can postulate additional symmetries to set the coupling constants to zero (so that you won't have naturalness problems - coupling constants extremely small). And although the general symmetry allows those terms, the extra one is going to kill them.

Higgs may still be controversial..

Here are the graphs which showed the Higgs discovery from CMS and ATLAS. It's the graphs which made those two organizations to publish the papers in which they claimed to have found a new particle. From an experimental point of view, these results only need better statistical corrections which will be available by the time LHC starts operating again. It is a common knowledge however, and after further studies, that the new particle is indeed the Higgs and we only need time to pile up more data to get better sigmas.

This article is from 2012, one week after the discovery of the particle got announced. It is completely outdated.

It is uncontroversial that ATLAS and CMS found "a" Higgs boson. There might be more (but nothing else has been found so far), but the new particle is clearly a Higgs boson.

New results indicate that new particle is a Higgs boson (March 2013)
The birth of a Higgs boson (May 2013 - it is simply called "Higgs boson" since then).

 

[ChrisVer]

additionally again, it's a Standard Model Higgs (un)fortunately...without making clear whether there is any more extra physics beyond it or not... leaving us only with the chance of finding a 2nd one or not to make sure. Am I the only one who finds this irritating? Out of so much free region, for it to go and "stand" right between the MSSM and SM limits...

There is a thread like this every week, just see one of the other 100 duplicates, damn. seriously someone give me a week we went without a "higgs particle found?" In the high energy and nuclear physics section. Not a rhetorical question.

The last post in this thread was in July 2014.

 

[Superposed_Cat]

was in front page, many apologies. Must have been made a sticky for that reason.

 

[mfb]

It is sticky for exactly that reason.
