“…The B → f 0 (980)K reaction is also studied in [35], again parametrizing the amplitude and discussing about the f 0 (980) nature as a qq or a tetraquark state.…”

$${\bar{B}}^0$$ B ¯ 0 , $$B^{-}$$ B - and $${\bar{B}}^0_s$$ B ¯ s 0 decays into $$J/\psi $$ J / ψ and $$K {\bar{K}}$$ K K ¯ or $$\pi \eta $$ π η

“…These findings have generated excitement in the a e-mail: liangwh@mailbox.gxnu.edu.cn b e-mail: xiejujun@impcas.ac.cn c e-mail: oset@ific.uv.es hadron community. Studies of weak B and D decays into two final mesons had got some attention [9][10][11][12][13][14] in recent years. The order of magnitude of the f 0 (980) production was predicted in Ref.…”

Consistent scenario forB→PSdecays

“…In a similar way one can argue that in order to extract signals of possible new physics, the contribution of low lying conventional physics has to be known in detail, including the contributions of the scalar mesons [16]. We believe that the understanding of the physical origin of the hierarchy of scales appearing in the B → P S decays can shed some light on the nature of the scalars [17,18]. Complementary information on the nature of the scalars may be obtained from D → P S physics [19]: in the first case through the decay constants,f s while in the latter through the F DS form factors.…”
