R symmetry

R symmetry is a type of mathematical symmetry that involves rotating a system or object around a central point or axis, often by specific angles, so the system appears unchanged. In physics, particularly in particle physics, R symmetry refers to a property where certain particles and their interactions remain consistent when certain transformations are applied, often related to the conservation of a specific quantity called R-charge. Think of it as a rule that allows the system to look the same after a specific "twist," helping scientists understand fundamental behaviors and conservation laws within complex physical theories.
