Physicists have Found what looks like an entire family of latest particles in the LHC

Physicists working with the huge Hadron Collider loveliness experiment (LHCb) have discovered what appears to be an entire family of latest particles that our current physics models can’t give details.
The existence of these latest forms of matter, known as tetraquarks, challenges our present sympathetic of the role they play inside the protons and neutrons that create up atoms - the fundamental building blocks of everything we recognize and love in the Universe.
We looked at each known particle and process to make sure these four structure couldn’t be explain by any pre-existing physics," one of the group, Thomas Britton from Syracuse University, told Sarah Charley at Symmetry. "It was like boiling a six-dimensional cake with 98 ingredientsand no recipe - presently a picture of a cake."
So 1st off, what’s a tetraquark? In their simplest form, quarks are minuscule particles that build up inside the protons and neutrons inside atoms, smashing about and annihilate every other at near-light speed.
As this video by Physics Girl explain, according to the current standard model of physics, quarks can come in six dissimilar types, or 'flavours': up, down, top, bottom, bizarre and charm. They’re all held together by still smaller particles called gluons, and depending on their mass, are secret as heavy or light.

Until recently, it was thought that quarks just come in groups of two or 3, but in 2014, physicists at the LHCb - one of seven particle physics detector experiments at the great Hadron Collider accelerator at CERN in Switzerland - confirmed the survival of a four-quark particle called a tetraquark.
Then last year, they one-upped this detection by confirming the existence of one more type of quark - a five-quark particle, or pentaquark.
None of this was easy, as knowledgeable by a separate team of researchers from the Fermilab subdivision physics facility close to Chicago, who announced that they too had exposed a new tetraquark previous this year, only to be met with a whole group of scepticism.
But currently the Syracuse team at the LHCb - which offer far more discovery sensitivity than the Fermilab particle accelerator - has identified four latest types of tetraquarks that appear to go to the same exotic family.
"What we have exposed is a unique system," says one of the team, Tomasz Skwarnicki. "We have four foreign particles of the same type; it’s the first time we have seen this and this detection is already helping us distinguish flanked by the theoretical models."

The latest particles have been named X(4140), X(4274), X(4500), and X(4700) following their respective masses, and each one has been establish to contain a unique mixture of two charm quarks and two strange quarks. This make them the first four-quark particles found to be collected entirely of heavy quarks, Symmetry reports.
By 'exciting' the person quarks inside their new tetraquark particles, the researchers were able to observe their single internal structure, mass, and quantum information. In doing so, they exposed something that doesn’t fit with present physics models that work with so-called normal particles, such as composite hadrons built from also a quark and an anti-quark, or three divide quarks, CERN reports.
Physics are now annoying to come up with new models to give details their results.
The team is pregnant one of two possibilities to be confirmed with additional research: theoretical psycists are either going to have to explain the survival of this new family of particles, or they could be idenfified as the result of strange 'ripple effects' emanating from never-before-seen behaviours of obtainable particles.
"The molecular clarification does not fit with the data," Skwarnicki told Charley at Symmetry.
"But I personally would not end that these are absolutely tightly bound states of four quarks. It could be likely that these are not even particles. The effect could show the complex interplays of recognized particle pairs frivolously changing their identity."
