Sentences with phrase «proton collisions»
"Proton collisions" refers to the interaction and collision between two protons, which are particles found in the nucleus of an atom. It is a term commonly used in particle physics to describe experiments or observations where protons collide with each other to study their properties and understand the fundamental nature of matter.
