SLC experiments

Definition

SLC experiments, or Superconducting Linear Collider experiments, are designed to probe the electroweak interactions by investigating the properties of the W and Z bosons, the mediators of the weak force. These experiments aimed to create high-energy collisions that could produce these bosons, thereby providing insights into the unification of electromagnetic and weak forces as described in electroweak theory.
