With this, my heart is beating even faster.
So please everybody get ready
for the next 15 minutes.
[laughter]
Hope it is exciting and enjoyable.
OK, now it is very exciting.
This is the limit for the 2011 (dataset).
But the next one is the limit for the 2012.
[laughter]
Off-camera: "Everybody quiet, now."
[laughter]
Everybody quiet? OK.
OK, this is true unblinding.
OK, 1, 2, 3, we are going to look at it, OK?
OK, so this is what we see in the 2012 cut-based analysis.
I don't list the numbers here, you can see this by eye.
And this is the combined limit
for the 2011 and the 2012 (datasets).
And I'm going to show you the p-value
in the next slide.
OK, so this is the significance of the 2012 (dataset).
The black is the combined significance.
The red is for the tight di-jet category.
And the rest, which is very difficult to see by eye,
is for different categories.
And the truly unblinding is on the next slide
which is the combined result of the 2011
and the 2012 (datasets).
OK, so this is the p-value of 2011 and 2012.
This black one, OK, is the combined.
You can see it is beyond which line? 1, 2, 3, and 4.
[laughter]
The green is for the 7 TeV
and the magenta is for the 8 TeV.
[applause]
Christoph Paus: The plot shows fundamentally
that we have consistent 2011 and 2012 data
which both show an excess of about 3 standard deviations
at about 127... (1)25, sorry...
and what it shows once we combine is that
it goes to over 4 standard deviations.
All of these values are local p-values.
We got 40% more 8 TeV data
so now we are at 5.3 inverse femtobarn
and we've gone through all of the needed steps
in order to reopen the box.
This means that we've resynchronized among
the different frameworks.
we've recalculated all the efficiencies,
data-to-Monte-Carlo correction factors
and we've rederived the energy-scale and
resolution corrections from the data.
We've also re-run the algorithm that chooses the
background model for the fits in the mass distribution
and we've gone through the full unblinding procedure
actually, just some 16 hours ago.
I think we would all like to thank everybody who takes part in
data taking, data certification,
Monte Carlo sample production, etc. etc.
It's thanks to all of you, it's thanks to all of us
that we can have 5.35 inverse femtobarn
used in this particular analysis.
We still, from this top-up, gain
at least 10% on the expected limit
on the combination of 7 and 8 TeV limits.
Of course, if we think only about 8 TeV limits
it's of course a much larger, uh, gain.
These are the combined limits for 7 and 8 TeV.
You have on the left the cut-based analysis result
and on the right the mass-factorized analysis result.
And then if we move to the p-values
on the left is the result of the cut-based
both of these plots are broken down into
7 and 8 TeV and the combination.
And you see in the mass-factorized
something like 4.1 sigma local p-value.
Thanks to the effort of all of us, all of you
we've been able to top-up with 5.35 inverse femtobarn,
we observe a 4.1 sigma excess at 125 GeV
and this is across three different analyses
performed in two independent frameworks.
So, I personally think that this begs for interpretation.
Thank you.
[applause]
I will give the status of the CMS Higgs search.
This is a very, very preliminary result
but we think it's very strong, it's very solid.
Otherwise we wouldn't present it.
I wanna really dedicate this to the CMS Collaboration.
It's a fantastic collaboration. This is 
a picture we took last week. We had a party.
This is only four or five hundred people.
Remember there are 4000 people in the experiment.
Um, this is not the real CMS detector.
That's down underground,
this is the spare that we keep upstairs.
[laughter]
So for the low-mass searches which I'll
concentrate on today,
we look for b-bbar, tautau,
WW, ZZ and two photons.
And we get very good mass resolution in these two channels.
What you see here is now the p-values.
This is the probability that the background could fluctuate
to this extent and you see
combining the two years' (data) we're beyond 4 sigma.
About 4.1 standard deviations.
If you look at the p-values
well, our expected significance for the Standard Model Higgs
at 125.5 is 3.8 sigma
and what we're seeing is 3.2.
If we combine the ZZ and gamma-gamma.
this is what we get. They line up extremely well
and in the region of 125 GeV
they combine to give us
a combined significance of five standard deviations.
[applause]
These are the two high-sensitivity channels.
This is adding the W. Now if we add the other two channels
we fall below 5 sigma, to 4.9 sigma.
And we conclude by saying that we have observed
a new boson with a mass of 125.3 plus-or-minus .6 GeV
at 4.9 standard deviations.
I would like to thank the Member States
of CERN. I can say this. I'm not from a Member State
but I think it's extraordinary that they've opened CERN up
and these projects to all countries in the world
and, uh, that's a magnificent thing because
these results are now global and shared
by all of mankind I think.
So I thank you for that.
[applause]
