The Standard Model describes elementary particles and their behaviour. Even though it is currently the best description there is of the subatomic world, it does not explain the complete picture. For this reason, theoreticians have developed models beyond the Standard Model, which would complete it. In this context, the LHCb experiment searches for new physics by looking for the effects of possible new particles in rare decays of particles that contain a beauty quark (B particles).

Recently, LHCb physicists have been studying the angular distribution of the particles coming from one of these rare B particle decays (B → K*μμ), a parameter that is highly sensitive to the effects of new particles. The new results are certain to draw the attention of physicists worldwide, as theorists consider the many possible implications.
