Description
Chiral Symmetry Breaking is one of the fundamental effects within the realm of strong interaction and it is responsible for the large mass of hadrons, in comparison to the light quark masses. From a theoretical point of view, there is a spontenous chiral symmetry breaking and explicit ones. The first effect provides the largest contribution to the hadron mass and is due to specific properties of the ground state of QCD. The second effect is due to the finite mass of the quarks. Experimentally, people look for a clear signature of chiral symmetry restoration, meaning an evidence that a transition from the broken symmetry to a partially restored symmetry can be obtained in the laboratory, if conditions of high temperature or baryonic densities are realized. These searches have been carried out for decades, since a detailed understadning of the mechanism responsible for the hadron masses is key in nuclear physics. The intro will introduce the topic and provide some examples of experimental searches. More details will be discussed in the discussions during the meeting.
