Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
First evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)

Alonopsis aureolata Doolittle 1912
Alonopsis aureolata Doolittle, 1912 Doolittle, 1912: 561–565, Pls. 42–43; Kubersky, 1977: 656–663, figs 3–20 (americana). Type locality. Lake Sunapee, Sullivan County, New Hampshire, USA. Holotype: immature female on a slide, U. S. National Museum (cat. 4 # 44366), from Lake Sunapee, Sullivan County, New Hampshire, USA collected 22.04. 1910. Material. 37 parthenogenetic females from Sebago Lake, Maine, USA, 0 9.07. 1966, coll. D. G. Frey, National Museum of Natural History (Washington DC, USA), Frey’s collection sample 1912. Description. Parthenogenetic female. Body (Fig. 6 A, C, E–F) height-length ratio about 0.59–0.63. Valves (Fig. 6 G–H) and head as for genus. Head shield (Fig. 7 A) with very short, broadly rounded rostrum. Head pores as for genus (Fig. 7 B), IP/PP ratio about 1.5–2 in adult. Labrum as for genus (Fig. 7 C–D). Thorax, abdomen and postabdomen (Fig. 6 B, D, I–J) as for genus, same as in the previous species. Antennule (Fig. 7 F), antenna (Fig. 7 D) and limb I (Fig 7 G–H) same as in the previous species. Limb II (Fig. 7 I) with scrapers 7 and 8 of similar size and shape, armed with 12–15 long, thick denticles. Limbs III (Fig. 7 J–L) and limb IV (Fig. 8 A–C) same as in the previous species. Limb V (Fig. 8 D) as for genus, incursion between exopodite lobes as obtuse angle. Limb VI (Fig. 8 E) with clusters of marginal setules in studied specimens of different proportions compared to the previous species. Male. According to description of Kubersky (1977), body shape is similar to that of the previous species. Postabdomen (Fig. 8 F) narrowing distally, but curved, with irregularly curved ventral margin and concave postanal margin, postanal angle defined, obtuse. Position of sperm ducts, armament of postabdomen, postabdominal claws similar to the previous species. Descriptions and drawings of antennule and limb I in description of Kubersky (1977) are somewhat vague. These structures appear to be similar to these of the previous species, but some differences possibly remain overlooked. Size. In studied material, length of female of juvenile instar I— 0.41–0.46 mm; juvenile instar II— 0.50–0.57 mm; adult female— 0.62–0.89 mm.Published as part of Sinev, Artem Y. & Atroschenko, Margarita M., 2011, Revision of the genus Alonopsis Sars, 1862 and its position within Aloninae (Cladocera: Anomopoda: Chydoridae), pp. 1-17 in Zootaxa 2800 on pages 13-14, DOI: 10.5281/zenodo.20359
Measurement of the time-dependent CP asymmetry in B0 -> J/ψ KS0 decays
This Letter reports a measurement of the CP violation observables SJ/ψK0S and CJ/ψK0S in the decay channel B0→J/ψK0S performed with 1.0 fb−1 of pp collisions at s√=7 TeV collected by the LHCb experiment. The fit to the data yields SJ/ψK0S=0.73±0.07(stat)±0.04(syst) and CJ/ψK0S=0.03±0.09(stat)±0.01(syst). Both values are consistent with the current world averages and within
expectations from the Standard Model
