Scientists at CERN have confirmed the existence of a new 'exotic' particle
International team used the Large Hadron Collider beauty (LHCb) detector
The particle was first detected in 2007 but it has only now been confirmed
Dubbed Z(4430), the discovery challenges existing models of physics
It may also indicate that a new type of neutron star, a quark star, exists
In the early 1930s, scientists were fairly confident they understood subatomic physics.
That was until dozens of new elementary particles were discovered in the 1950s, forcing scientists to rewrite their models.
Now a new particle, first detected in 2007 but not confirmed until now, could send them back to the drawing board as they try to figure out whats going on at a subatomic level.
This particular discovery delves into a particularly complex branch of physics.
It was made by physicists at the Large Hadron Collider beauty (LHCb) Collaboration at Cern in Geneva, Switzerland.
LHCb is a multinational experiment designed to identify new forces and particles in the universe....

In the early 1930s, scientists were fairly confident (meaning there was consensus) they understood subatomic physics.
The vague term ‘fairly confident’ needed definition in today’s modern language.
Considering that both big and small have no finite limits, there is no limit to the discoveries yet to be made.
If I had the bus fare I’d go down there and explain it to them. It is so simple.
Read as "it was settled science."
See the old movie
The science is settled.
I cannot imagine particles writing anything. Only humans write.
Z(4430) causes global warming. >:->
What size Planck were you using as your cutting board?
That’s what makes it all so much fun. Matter is an emergent property of consciousness and consists of chosen observations in an infinite sea of potential. So the more we ‘know’ the more we ‘see’. But all we’re really doing is playing with the illusion while imagining we’re ‘discovering’ the things we’re making up.
I hate those fudge factors.
Anti-quarks are just SO annoying.
I suppose humans are made out of particles :-)
Sheldon.......... Sheldon Cooper....... is that YOU?
That is very true but not many people see that.
Planck’s Constant times something, IIRC
This is qualitative, though -- discovery of a new way in which building block particles can be combined. You can't have limitless permutations and combinations of quarks because most would violate quantum chromodynamics and other field theory.
They had a working understanding of nuclear physics, and this has stood up. The further forays deeper into the subatomic realm, or realms, has been ongoing through the 60's, 70's and later. I remember the excitement over the J/psi particle, back in the day. It too, was a "resonance", i.e. a "bump" in a curve of reaction cross section versus energy.
I note the Upsilon Meson was discovered about the same time. Here's a very quaint figure from the paper announcing it:
Now we have detectors the size of battle ships with INSANE computing power ( based on 1930's concepts of solid state physics, however finally honed, ) and we get tetraquarks.
Oh, fine, then--get all technical about it.
More every day.
