   Missing mass spectroscopy with the (e,e′K+) reaction was performed at Jefferson Laboratory's Hall C for the neutron rich Λ hypernucleus 9ΛLi. The ground state energy was obtained to be Bg.s.Λ=8.84±0.17stat.±0.15sys. MeV by using shell model calculations of a cross section ratio and an energy separation of the spin doublet states (3/2+1 and 5/2+1). In addition, peaks that are considered to be states of [8Li(3+)⊗sΛ=3/2+2,1/2+] and [8Li(1+)⊗sΛ=5/2+2,7/2+] were observed at EΛ(no. 2)=1.74±0.27stat.±0.11sys. MeV and EΛ(no. 3)=3.30±0.24stat.±0.11sys. MeV, respectively. The EΛ(no. 3) is larger than shell model predictions by a few hundred keV, and the difference would indicate that a 5He+t structure is more developed for the 3+ state than those for the 2+ and 1+ states in a core nucleus 8Li as a cluster model calculation suggests.

   A<sc>bstract</sc> An angular analysis ofB⁰→ K^*0e⁺e⁻decays is presented using proton-proton collision data collected by the LHCb experiment at centre-of-mass energies of 7, 8 and 13 TeV, corresponding to an integrated luminosity of 9 fb⁻¹. The analysis is performed in the region of the dilepton invariant mass squared of 1.1–6.0 GeV²/c⁴. In addition, a test of lepton flavour universality is performed by comparing the obtained angular observables with those measured inB⁰→ K^*0μ⁺μ⁻decays. In general, the angular observables are found to be consistent with the Standard Model expectations as well as with global analyses of otherb → sℓ⁺ℓ⁻processes, whereℓis either a muon or an electron. No sign of lepton-flavour-violating effects is observed.
