"Non-anomalous global sym" refers to a type of symmetry present in the mathematical framework of the Standard Model of particle physics. It is a type of symmetry that is not broken, meaning it is present at all energy scales and remains unchanged.
Unlike other types of symmetries in the Standard Model, "Non-anomalous global sym" is not affected by quantum anomalies, which are deviations from classical symmetries that arise in certain quantum field theories. This allows it to be a more fundamental and stable symmetry in the model.
"Non-anomalous global sym" affects all particles in the Standard Model, including fermions (such as quarks and leptons) and bosons (such as photons and W and Z bosons). It is a fundamental property of the model and is necessary for the consistency of the theory.
"Non-anomalous global sym" is a symmetry that dictates the interactions and properties of particles in the Standard Model. It helps to determine the strength and type of forces between particles and plays a crucial role in the predictions and calculations of particle behavior.
Currently, there are no known violations of "Non-anomalous global sym" in the Standard Model. However, some theories beyond the Standard Model, such as supersymmetry, predict the breaking of this symmetry at very high energies. Further research and experiments are needed to test these predictions and fully understand the role of this symmetry in particle physics.
