Asymmetric Colliders

Definition

Asymmetric colliders are particle accelerators designed to collide beams of particles with different energies or masses, creating unique conditions for studying fundamental interactions. This setup allows researchers to investigate phenomena that may not be observable in symmetric collisions, offering insights into B-physics and flavor-changing processes, particularly in the context of quark mixing and CP violation.
