Meet CERNs New Particle A DoubleCharm Baryon

The video explores the discovery of a new particle at CERN, made of two charm quarks and one up quark, and its implications for studying the strong force. It also discusses the evolution of life from microscopic to larger forms, focusing on rangeomorphs and their growth influenced by ocean chemistry changes.

What is the composition of the newly discovered particle Psi CC++?

• Two up quarks and one down quark

• Two charm quarks and one up quark

• Two strange quarks and one top quark

• Two bottom quarks and one charm quark

Which force is primarily studied using the new particle Psi CC++?

• Strong nuclear force

• Gravitational force

• Electromagnetic force

• Weak nuclear force

What was a key difference between the new CERN particle and the one found by Fermi Lab in 2002?

• The CERN particle is lighter

• The Fermi Lab particle decayed faster

• The CERN particle has a different charge

• The Fermi Lab particle was made of three up quarks

What are rangeomorphs believed to be?

• Modern fish

• Single-celled organisms

• Primitive animals

• A type of plant

How did changes in ocean chemistry affect rangeomorphs?

• They grew taller and thinner

• They started living on land

• They developed mouths and guts

• They became extinct
