000001587 520__ $$aWe have studied the event shape variable R2 represented by the ratio of the second and zeroth Fox-Wolfram moment. The variable R2 is a good indicator to understand if the collision data of the SuperKEKB are occurring at the Y(4S) resonance. The study on the shape variable R2 is used to derive the total number of produced BB pairs.
