“…In fact, as noted in Ref. [31], all current theoretical results have such similar situation, even The CP asymmetry parameters (in units of 10 −2 ) ofB 0 s → K ± K * ∓ , π ± ρ ∓ , and K 0K * 0 (K 0 K * 0 ) decays. The unavailable results are not listed.…”

Motivated by the recent LHCb measurements onB s → π − K * + andB s → K ± K * ∓ decay modes, we revisit the B s → P V decays within QCD factorization framework. The effects of hard-spectator scattering and annihilation corrections are studied in detail. After performing a χ 2 -fit on the end-it is found that although some possible mismatches exist, the universalities of X i,f A and X H in B s and B u,d systems are still allowed within theoretical uncertainties and experimental errors. With the end-point parameters gotten from B u,d → P V decays, the numerical results and detailed analyses for the observables of B s → πK * , ρK, πρ, πφ and Kφ decay modes are presented. In addition, we have identified a few useful observables, especially the ones ofB s → π 0 φ decay for instance, for probing hard-spectator scattering and annihilation contributions.

Two types of average neutron-proton interaction formulas are compared: In the first type, neutronproton interactions for even-even and odd-A nuclei extracted from experimental binding energies show a smooth behavior as a function of mass number A and are dominated by the contribution from the symmetry energy. Whereas in the second type large systematic staggering is seen between even-A and odd-A nuclei. This deviation is understood in term of the additional neutron-proton interaction in odd-odd nuclei relative to the neighboring even-even and odd-A systems. We explore three possible ways to extract this additional interaction from the binding energy difference of neighboring nuclei. The extracted interactions are positive in nearly all cases and show weak dependence on the mass number. The empirical interactions are also compared with theoretical values extracted from recent nuclear mass models where large unexpected fluctuations are seen in certain nuclei. The reproduction of the residual neutron-proton interaction and the correction of those irregular fluctuations can be a good criterion for the refinement of those mass models.

“…δV 2p−2n can be generalized to δV ip− jn between the last i proton(s) and the last j neutron(s) [10][11][12][13][14]. As for nuclear charge radii R ch (Z, N), similar difference formula exist.…”

Abstract. The masses and sizes of nuclear ground states constitute two of the most precise and extensive arrays of experimental information. These data make a model-independent view of microscopic nuclear structure possible. Relevant differential observables of nuclear mass and charge radius can be highly sensitive to nuclear shape transitions. In this contribution, we examine the correlation of these two bulk properties to nuclear shape transitions. By combining different observables, it is even possible to isolate shape transitions from nuclear shell closures.
