CERN to resume search for "Big Bang" secrets - Comments

Here's something I don't understand: Wasn't the LHC supposed to test the Higgs Boson hypothesis? I thought the question of the Higgs was supposed to be answered right away, so why does it still say everywhere that we don't know? Or are they doing the experiments about dark matter first?

Oh yeah, does anybody knows what happened with the experiments on Higgs Boson hypothesis?

No one can predict with certainty whether the boson exists, let alone the energy required to find it.
The collider is currently running at half its power and it won't go on-line at full power before the end of 2012 after certain upgrades are carried out.

The boson might be revealed earlier or even as we speak; after all, the current energy level constitutes a gargantuan novelty in itself.
That doesn't mean that the data are analysed in real time. Billions of collisions will have to be checked. I'm not familiar with the process and I don't know how long it will take, but it's certainly not instantaneous.

It will be a while before the HB is found. They are planning to shut down again next year to upgrade the magnet joints before the ramp up to a 7 TeV beam.

With 7 TeV collisions, and assuming that:

1. The LHC stays up for the entire planned time before the shutdown for the 14 TeV upgrade

2. The Higgs exists and is relatively light (~120 GeV), as expected

we should have enough luminosity integrated over time to see some signal from the Higgs. However, it probably won't be enough (5 standard deviations) to claim discovery. Also, if supersymmetry exists and the super particles are light, we should see some suggestive signals -- but nowhere near enough for discovery.

All this will change with 14 TeV collisions. We wouldn't need much luck to see the Higgs, becaues if it's heavy we would still see it. And, the super particle production rate will be ten times higher, so we should almost certainly see something if supersymmetry is real.

Thanks for the illuminating explanations. I should read up on this stuff ...

Hurry up already. We're not getting any younger here. This LHC first started to be hyped last century as a 'Deep Thought' that will be provide answers to the universe. Still another three years to go.

The entire Apollo program, from go-to-whoa, took less time.
