The motions of plasmas may be notoriously difficult to model, but they can be better understood by analysing what happens when protons are scattered by atoms of hydrogen. In itself, this property is ...

Inside high-energy proton collisions, quarks and gluons briefly form a dense, boiling state before cooling into ordinary particles. Researchers expected this transition to change how disordered the ...

A new study uses new techniques to calculate the cross sections of atoms which have been excited to higher energy levels. Researchers analyzed the behavior over a wide range of impact energies. The ...
