Impostor Higgs?

I recently came across this article, published in the respectable European Physical Journal A. (Apparently, there isn't any corresponding arXiv article for this, so I'm sorry if everyone isn't able to ...

Why can't we measure branching ratios of the Higgs at LHC?

There are theoretical predictions for SM Higgs decay branching ratios. What about the experimental results on BRs? All that I found was measurements of signal-strengths $\mu = \frac{(\sigma \cdot ...

Predicting the mass of the Higgs particle

Physicists in Europe said that only after combining data collected at a laboratory in Switzerland with data collected at a laboratory in the U.S, were they finally able to announce the discovery of a ...

Why is the Higgs boson created so infrequently at the CERN collider?

Although each collision at CERN has the available energy to create a Higgs boson each time, the vast majority of the time it does not create one. I suspect that part of the reason for this is that ...

Some very basic questions on the Higgs Boson

What exactly is a boson? Is the Higgs boson the cause of gravity or a result of it? Does the collision of particles at the LHC create a gravity field or waves or somehow interact with the gravity ...

What if the 126 GeV particle found at LHC that LOOKS like the Higgs is actually not the Higgs Boson?

I am suspicious of the Higgs announcement. Press mania aside, the scientists seem careful to say only that "we've found something which looks like the Higgs Boson". The difference between ...

Which collision energy at LHC is better for hunting 125 GeV Higgs, 7 TeV, 8 TeV or 14 TeV?

Increasing collision energy in hadron collders doesn't always improve the abiilty to hunt down the Higgs. I know that if the Higgs mass is just above LEP exclusion, then even 7 TeV is too high to be ...

Why search for theoretical particle? [closed]

Just out of curiosity, is there any special purpose in human life, the search for some theoretical particle for its uncertain benefit, to prove theory of everything which doesn't serve any advancement ...

How should one combine the uncertainties from the ATLAS and CMS measurements?

First off, a naive theorist question - How are measurements divided between the different detectors at the LHC? I would imagine that for a short run time, say, the CMS detector is active and all the ...

What's the Standard Model width of a 125 GeV Higgs?

There's a fairly broad mass spread in the new results out of Atlas and CMS. I'm curious how this fits with the expected SM width.

Are there any models for two light Higgs?

The LHC results today seem to have two possible Higgs peaks, one at 119 GeV and the other at 125-126 GeV. All the multi-Higgs supersymmetry models I've seen that have multiple Higgs have only one ...

Might the LHC see nothing new at all?

There's no guarantee that supersymmetry (or more exotic new physics) will be seen at the LHC. Meanwhile, it's standard lore that a Higgsless standard model becomes nonunitary somewhere in the vicinity ...
