The video discusses the discovery of an exotic particle at CERN using the Large Hadron Collider. This particle, composed of two charm quarks and two charm anti-quarks, was identified by filtering out ordinary collisions. The video explores whether the particle is a weakly bonded pair or a strongly bonded tetra quark. It highlights the significance of this discovery, as particles with four heavy quarks of the same type have not been observed before.

What is the composition of the exotic particle discovered at CERN?

• Four charm quarks

• Two up quarks and two down quarks

• Three charm quarks and one charm anti-quark

• Two charm quarks and two charm anti-quarks

What role do superconductors play in the Large Hadron Collider?

• They filter out background noise

• They detect exotic particles

• They accelerate protons to near light speeds

• They cool down the collider

How do scientists identify the exotic particle among other collisions?

• By using a special camera

• By increasing the collider's temperature

• By filtering out ordinary background collisions

• By slowing down the protons

What makes quarks unique as elementary particles?

• They are the building blocks of all matter

• They are the heaviest particles

• They are only found in exotic particles

• They can exist independently

What is uncertain about the nature of the discovered exotic particle?

• Whether it can be used in everyday technology

• Whether it is made of three quarks

• Whether it is a weakly bonded pair or a strongly bonded tetraquark

• Whether it is a new type of proton
