The LHC is back again with a new sensation.
For the first time ever, there is proof of
the decay of the famous Higgs-Boson into two
Bottom-Quarks.
What?
Are you serious?
What does this mean for the future and why
is this such a great sensation?

So, this is what they look like, the data
tapes of CERN, the Large Hadron Collider,
short: LHC.
There are 600.000 proton collisions on it
that were close to the speed of light.
30 minutes of running time on the LHC.
The data is recorded among others here at
the ATLAS detector.
And in June of 2012 the Higgs-Boson was first
discovered in this data.
An absolutely crazy particle.
Through this particle, the existence of the
Higgs Field has been proven.
It provides everything with mass.
The attribute of matter, which leads to the
space-time curvature and therefore pulls us
to the earth for example.
Although Gravitation is not a force, it is
the curvature of space-time.
And the attribute of the matter, mass, which
leads to the curvature is provided by the
Higgs-Boson.
This all happened at the LHC, one of the biggest
and most expensive machines of mankind.
It cost about 4,75 billion dollars, a ring
with a length of approximately 27 kilometers,
equipped with strong detectors, in which protons
or lead ions collide at a speed close to the
speed of light.
During these collisions, the particles decay
into their components, and if everything goes
well, those are tracked down by the huge detectors.
Over several decades, a standard model of
the elementary particle physics was created.
Using the LHC and its precursors, this model
was proven over and over again with its quarks,
leptons and bosons.
But, proving the breakdown of the higgs-boson
into two bottom-quarks, with the standard
model was tricky because these particles also
result in other processes of decay.
And that even though, higgs-bosons usually
decay into those two particles.
According to the standard model, higgs-bosons
break down into these two quarks 60 percent
of the time.
But Kerstin Tackman from the ATLAS-detector
at CERN had this to say about the matter:
„LHC-collisions generate great amounts of
Bottom-Quark-Pairs.
This makes it really difficult, to filter
out those, that are actually from the decay
of the higgs-boson.“
So how can we identify the decay of the higgs-boson?
Artificial intelligence, meaning algorithms
that can adapt would be the solution.
They were looking for decays in the data,
in which a Z-Boson or a W-Boson appears.
And this has now worked.
„This proof is a milestone in the research
of the higgs-boson.
We have now observed all couplings of the
higgs-boson with the heavy quarks and leptons
of the third generation and also the different
important kinds of how these particles are
created.“
is what Karl Jakobs said, who is a speaker
at ATLAS.
This has again shown, that the standard model
of the elementary particle physics is true.
And also the Yukawa-Coupling, which means
the exact coupling of the higgs-field with
the loaded elementary particles, like quarks
and leptons, which gives them their mass.
Wow.
We have come a little closer to one of the
biggest mysteries, again.
„Thanks to our experiments, we are getting
closer and closer to the nature of the higgs-particle
- the particle which counts as a portal to
a new kind of physics“ said Eckhard Elsen,
CERN-director of research and computing.
Slowly, the research-teams at CERN are advancing
to an area, where a new kind of physics could
be hiding.
Wow!
