“…The great efforts have been extensively contributed to the exclusive B → P P, P V, and V V decays at both theoretical and experimental aspects in the past decades, for example, see Refs. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18], where P and V denote the S-wave pseudoscalar and vector states, respectively. However, the known "puzzles", for example, the large observed B 0 → π 0 π 0 , B 0 → ρ 0 π 0 , and B → Kη ′ decay rates, the experimental inequality of the direct CP asymmetries between B ± → K ± π 0 and B 0 → K ± π ∓ modes, the unknown mechanism of the polarization in the penguin-dominated B → V V processes etc., are still not elegantly resolved [17][18][19].…”
