By solving exactly the Faddeev equations for the bound-state problem of three mesons, we demonstrate that current theoretical predictions pointing to the existence of a deeply-bound doubly bottom axial vector tetraquark lead to the existence of a unique bound state of three B mesons.We find that the BB * B * − B * B * B * state with quantum numbers (I)J P = (1/2)2 − , T bbb , is about 90 MeV below any possible three B-meson threshold for the reported binding of the doubly bottom axial vector tetraquark, T bb .

“…The effect of the D term in Eqs. (10) and (11), for example, is strongly angle dependent-for R parallel or antiparallel to RЈ, the R range of T R2 is drastically reduced due to large D values, whereas for R Ќ RЈ this cutoff effect is absent. This angular dependence is schematically depicted in Fig.…”

“…We should mention however that there is another interesting possibility of coupling, for example, J =2,3 initial N N states to L = 0 intermediate N ⌬ , ⌬ N, or ⌬ ⌬ states, which then can decay into mesons by a short range annihilation mechanism. This approach was investigated for total annihilation cross sections in [10,11] but not pursued for differential cross sections.…”

Quark model intrinsic wave functions of highly energetic pions in the reaction p p → − + are subjected to a relativistic treatment. The annihilation is described in a constituent quark model with A2 and R2 flavor-flux topology, and the annihilated quark-antiquark pairs are in 3 P 0 and 3 S 1 states. We study the effects of pure Lorentz transformations on the antiquark and quark spatial wave functions and their respective spinors in the pion. The modified quark geometry of the pion has considerable impact on the angular dependence of the annihilation mechanisms.

“…The 3 P 0 model is fundamentally based on a flux tube picture of the quark confinement. Based on the flux tube picture of the quark confinement, the strong decay and pp annihilation processes are also well described in a 3 S 1 model [58][59][60][61].…”
