Structure of the decay _ B0s. J=.p_p- is studied using data corresponding to 3 fb- 1 of integrated luminosity from pp collisions produced by the LHC and collected by the LHCb detector. Five interfering p_p- states are required to describe the decay: F-0(980), F-0(1500), F-0(1790), F-2 (1270) and F-2(1525) An alternative model including these states and a nonresonant J=.p_p- component also provides a good description of the data. Based on the different transversity components measured for the spin- 2 intermediate states, the final state is found to be compatible with being entirely CP odd. The CP- even part is found to be < 2.3% at a 95% confidence level. The f 0d500_ state is not observed, allowing a limit to be set on the absolute value of the mixing angle with the f 0d980_ of < 7.7 at a 90% confidence level, consistent with a tetraquark interpretation of the f(0)(980) substructure

“…The three processes are Cabibbo allowed and the rates of production are big compared to those of theB 0 decays into J/ψ and one of these resonances, where necessarily one of the vertices, the V cb , is Cabibbo suppressed [19,20,21]. On the other hand, the a 0 (980) has not been reported inB 0 ,B 0 s decays.…”

“…The original appeal of this mode is that it was assumed to be predominantly an S-wave decay, and thus not in need of the complex multidimensional fit just described. The study of the Dalitz plot of B 0 s → J/ψπ + π − (Aaij et al, 2012a) revealed a more complex resonant structure. A combination of five resonant states are required to described the data (see (Aaij et al, 2014i)): f 0 (980), f 0 (1500), f 0 (1790), f 0 (1270), and f 2 (1525).…”

CP violation in the Bs0 system

We review experimental and theoretical studies of CP violation in the B 0 s system. Updated predictions for the mixing parameters of the B 0 s mesons expected in the Standard Model (SM) are given, namely the mass difference ∆M SM s = (18.3±2.7) ps −1 , the decay rate difference ∆Γ SM s = (0.085 ± 0.015) ps −1 , and the flavour specific CP asymmetry a s,SM fs = (2.22 ± 0.27) × 10 −5 and the equivalent quantities in the B 0 -sector. Current experimental values of ∆Ms and ∆Γs agree with remarkable precision with theoretical expectations. This agreement supports the applicability of theoretical tools such as the Heavy Quark Expansion (HQE) to these decays. CP violating studies in the B 0 s system provide essential information to test the SM expectations, and to unveil possible contribution of the new physics (NP). NP effects on ∆Ms of the order of 15% are still possible. The CP phase φs due to CP violation in interference of decays and mixing can accommodate effects of the order of O(100%). The semileptonic CP asymmetry a s sl due to CP violation in mixing could still be a factor of 130 larger than its robust SM expectation and thus provides a very clean observable for NP searches. Theoretical improvements that are necessary to make full use of the experimental precision are discussed.
