1. The problem statement, all variables and given/known data I'm doing a dissertation on heavy ion collisions and one of the things they look for in the collisions is chiral symmetry resolution - what is it? 2. Relevant equations 3. The attempt at a solution I understand that it is a type of symmetry that is usually broken but QCD predicts that it shouldn't break at high energies (like in a heavy ion collision) just not sure what sort of symmetry it is - Is it that you can't tell the difference between our universe and a mirror image of our universe or something?
