A Large Ion Collider Experiment

is the dedicated experiment to study collisions of heavy nuclei



ALICE will study collisions of heavy nuclei, like Pb.

WHY?

The collisions between Lead nuclei create little fireballs with temperatures 100 000 hotter than the centre of sun

•At this temperature, the protons and neutrons of the Lead nuclei

melt into their elementary components, the quarks and gluons

creating a state of matter called Quark Gluon Plasma for a very

brief instant of time. •Such state of matter must have existed at the extreme

temperatures of the early Universe a few microseconds after the

Big Bang
