We report four narrow peaks in the Ξ_{b}^{0}K^{-} mass spectrum obtained using pp collisions at center-of-mass energies of 7, 8, and 13 TeV, corresponding to a total integrated luminosity of 9  fb^{-1} recorded by the LHCb experiment. Referring to these states by their mass, the mass values are m[Ω_{b}(6316)^{-}]=6315.64±0.31±0.07±0.50  MeV, m[Ω_{b}(6330)^{-}]=6330.30±0.28±0.07±0.50  MeV, m[Ω_{b}(6340)^{-}]=6339.71±0.26±0.05±0.50  MeV, m[Ω_{b}(6350)^{-}]=6349.88±0.35±0.05±0.50  MeV, where the uncertainties are statistical, systematic, and the last is due to the knowledge of the Ξ_{b}^{0} mass. The natural widths of the three lower mass states are consistent with zero, and the 90% confidence-level upper limits are determined to be Γ[Ω_{b}(6316)^{-}]<2.8  MeV, Γ[Ω_{b}(6330)^{-}]<3.1  MeV and Γ[Ω_{b}(6340)^{-}]<1.5  MeV. The natural width of the Ω_{b}(6350)^{-} peak is 1.4_{-0.8}^{+1.0}±0.1  MeV, which is 2.5σ from zero and corresponds to an upper limit of 2.8 MeV. The peaks have local significances ranging from 3.6σ to 7.2σ. After accounting for the look-elsewhere effect, the significances of the Ω_{b}(6316)^{-} and Ω_{b}(6330)^{-} peaks are reduced to 2.1σ and 2.6σ, respectively, while the two higher mass peaks exceed 5σ. The observed peaks are consistent with expectations for excited Ω_{b}^{-} resonances.


Search for the rare decay eta ' -> pi(0)pi(0)pi(0)pi(0) at BESIII

Physical Review D American Physical Society 101 (2020) 32001

M Ablikim, M Achasov, P Adlarson, M Albrecht, M Alekseev, A Amoroso, YB Anita, I Balossino, K Begzsuren, J Bennett, J Bloms, I Boyko, R Briere, H Cai, A Calcaterra, G Cao, N Cao, J Chai, W Chang, J Chen, M Chen, W Cheng, H Dai, A Dbeyssi

Using a sample of 1.31×109 J/ψ events collected with the BESIII detector, we perform a search for the rare decay η′→4π0 via J/ψ→γη′. No significant η′ signal is observed in the 4π0 invariant mass spectrum. With a Bayesian approach, the upper limit on the branching fraction is determined to be B(η′→4π0)<4.94×10-5 at the 90% confidence level, which is a factor of 6 smaller than the previous experimental limit.


Measurement of the 𝜂𝑐(1𝑆) production cross-section in 𝑝 𝑝 collisions at 𝑠√=13 TeV

European Physical Journal C Springer Nature 80 (2020) 191

R Aaij, C Beteta

Using a data sample corresponding to an integrated luminosity of 2.0 fb−1, collected by the LHCb experiment, the production of the 𝜂𝑐(1𝑆) state in proton–proton collisions at a centre-of-mass energy of 𝑠√=13 TeV is studied in the rapidity range 2.0<𝑦<4.5 and in the transverse momentum range 6.5<𝑝T<14.0GeV. The cross-section for prompt production of 𝜂𝑐(1𝑆) mesons relative to that of the 𝐽/𝜓 meson is measured using the 𝑝 𝑝⎯⎯⎯ decay mode and is found to be 𝜎𝜂𝑐(1𝑆)/𝜎𝐽/𝜓=1.69±0.15±0.10±0.18. The quoted uncertainties are, in order, statistical, systematic and due to uncertainties on the branching fractions of the 𝐽/𝜓→𝑝𝑝⎯⎯⎯ and 𝜂𝑐→𝑝𝑝⎯⎯⎯ decays. The prompt 𝜂𝑐(1𝑆) production cross-section is determined to be 𝜎𝜂𝑐(1𝑆)=1.26±0.11±0.08±0.14μb, where the last uncertainty includes that on the 𝐽/𝜓 meson cross-section. The ratio of the branching fractions of 𝑏-hadron decays to the 𝜂𝑐(1𝑆) and 𝐽/𝜓 states is measured to be 𝑏→𝜂𝑐𝑋/𝑏→𝐽/𝜓𝑋=0.48±0.03±0.03±0.05, where the last uncertainty is due to those on the branching fractions of the 𝐽/𝜓→𝑝𝑝⎯⎯⎯ and 𝜂𝑐→𝑝𝑝⎯⎯⎯ decays. The difference between the 𝐽/𝜓 and 𝜂𝑐(1𝑆) masses is also determined to be 113.0±0.7±0.1MeV, which is the most precise single measurement of this quantity to date.

Observation of the decays chi(cJ) -> phi phi eta

Using a data sample of (448.1±2.9)×106 ψ(3686) decays collected by the BESIII detector at the Beijing Electron Positron Collider (BEPCII), we observe the decays χcJ→φφη(J=0,1,2), where the χcJ are produced via the radiative processes ψ(3686)→γχcJ. The branching fractions are measured to be B(χc0→φφη)=(8.41±0.74±0.62)×10-4, B(χc1→φφη)=(2.96±0.43±0.22)×10-4, and B(χc2→φφη)=(5.33±0.52±0.39)×10-4, where the first uncertainties are statistical, and the second are systematic. We also search for intermediate states in the φφ or ηφ subsystems, but no significant structure is seen due to the limited statistics.

Using a sample of (448.1±2.9)×106 ψ(3686) events collected with the BESIII detector, we perform the first partial wave analysis of ψ(3686)→K+K-η. In addition to the well established states, φ(1020), φ(1680), and K3∗(1780), contributions from X(1750), ρ(2150), ρ3(2250), and K2∗(1980) are also observed. The X(1750) state is determined to be a 1-resonance. The simultaneous observation of the φ(1680) and X(1750) indicates that the X(1750), with previous observations in photoproduction, is distinct from the φ(1680). The masses, widths, branching fractions of ψ(3686)→K+K-η, and the intermediate resonances are also measured.

Observations are reported of different sources of CP violation from an amplitude analysis of B^{+}→π^{+}π^{+}π^{-} decays, based on a data sample corresponding to an integrated luminosity of 3  fb^{-1} of pp collisions recorded with the LHCb detector. A large CP asymmetry is observed in the decay amplitude involving the tensor f_{2}(1270) resonance, and in addition significant CP violation is found in the π^{+}π^{-}S wave at low invariant mass. The presence of CP violation related to interference between the π^{+}π^{-}S wave and the P wave B^{+}→ρ(770)^{0}π^{+} amplitude is also established; this causes large local asymmetries but cancels when integrated over the phase space of the decay. The results provide both qualitative and quantitative new insights into CP -violation effects in hadronic B decays.

A measurement of the Ξcc++ mass is performed using data collected by the LHCb experiment between 2016 and 2018 in pp collisions at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 5.6 fb−1. The Ξcc++ candidates are reconstructed via the decay modes Ξcc++→Λc+K−π+π+ and Ξcc++→Ξc+π+. The result, 3621.55 ± 0.23 (stat) ± 0.30 (syst) MeV/c2, is the most precise measurement of the Ξcc++ mass to date.

A four-body amplitude analysis of the B− → D*+π−π− decay is performed, where fractions and relative phases of the various resonances contributing to the decay are measured. Several quasi-model-independent analyses are performed aimed at searching for the presence of new states and establishing the quantum numbers of previously observed charmed meson resonances. In particular the resonance parameters and quantum numbers are determined for the D1(2420), D1(2430), D0(2550), D∗1(2600), D2(2740) and D∗3(2750) states. The mixing between the D1(2420) and D1(2430) resonances is studied and the mixing parameters are measured. The dataset corresponds to an integrated luminosity of 4.7fb−1, collected in proton-proton collisions at center-of-mass energies of 7, 8 and 13 TeV with the LHCb detector.

The cross-sections of ψ(2S) meson production in proton-proton collisions at √s = 13 TeV are measured with a data sample collected by the LHCb detector corresponding to an integrated luminosity of 275 pb−1. The production cross-sections for prompt ψ(2S) mesons and those for ψ(2S) mesons from b-hadron decays (ψ(2S)-from-b) are determined as functions of the transverse momentum, pT, and the rapidity, y, of the ψ(2S) meson in the kinematic range 2 < pT < 20 GeV/c and 2.0 < y < 4.5. The production cross-sections integrated over this kinematic region are σ (prompt ψ(2S), 13 TeV) = 1.430 ± 0.005 (stat) ± 0.099 (syst) µb, σ (ψ(2S)-from-b, 13 TeV) = 0.426 ± 0.002 (stat) ± 0.030 (syst) µb.<br/> A new measurement of ψ(2S) production cross-sections in pp collisions at √s = 7 TeV is also performed using data collected in 2011, corresponding to an integrated luminosity of 614 pb−1. The integrated production cross-sections in the kinematic range 3.5 < pT < 14 GeV/c and 2.0 < y < 4.5 are σ (prompt ψ(2S), 7 TeV) = 0.471 ± 0.001 (stat) ± 0.025 (syst) µb, σ (ψ(2S)-from-b, 7 TeV) = 0.126 ± 0.001 (stat) ± 0.008 (syst) µb.<br/> All results show reasonable agreement with theoretical calculations

Using a 2.93     fb − 1 data sample of electron-positron collisions taken with the BESIII detector at a center-of-mass energy of 3.773 GeV, which corresponds to ( 8296 ± 31 ± 64 ) × 10 3 D + D − pairs, we search for the baryon and lepton number violating decays D + → ¯ Λ ( ¯ Σ 0 ) e + and D + → Λ ( Σ 0 ) e + . No obvious signals are found with the current statistics and upper limits on the branching fractions of these four decays are set at the level of 10 − 6 at 90% confidence level.


Improved sensitivity to the CKM phase gamma through binning phase space in B- -> DK-, D -> K+pi(-)pi(-)pi(+) decays

PHYSICS LETTERS B 802 (2020) ARTN 135188

T Evans, J Libby, S Malde, G Wilkinson

&#xA9; 2019 The Author(s) A binning scheme is proposed for D&#x2192;K+&#x3C0;&#x2212;&#x3C0;&#x2212;&#x3C0;+ phase space that will improve the sensitivity of a B&#x2212;&#x2192;DK&#x2212; analysis to the angle &#x3B3; of the Cabibbo-Kobayashi-Maskawa Unitarity Triangle. The scheme makes use of amplitude models recently reported by the LHCb collaboration. Assuming that a four-bin scheme optimised on the models retains a similar sensitivity when applied in data, it is estimated that the statistical uncertainty on &#x3B3; from the B-meson sample so far collected by the LHCb experiment will be as low as 5 degrees. This will be one of the most precise results available for any single decay mode in a B&#x2212;&#x2192;DK&#x2212; measurement. Quantum-correlated DD&#xAF; data accumulated by the CLEO-c experiment are analysed to provide first constraints on the coherence factors and average strong-phase differences in the four bins, which are necessary inputs for the measurement. These constraints are compared with the predictions of the model, and consequences for the measurement of &#x3B3; are discussed.

Searches are performed for both promptlike and long-lived dark photons, A^{'}, produced in proton-proton collisions at a center-of-mass energy of 13 TeV. These searches look for A^{'}→μ^{+}μ^{-} decays using a data sample corresponding to an integrated luminosity of 5.5  fb^{-1} collected with the LHCb detector. Neither search finds evidence for a signal, and 90% confidence-level exclusion limits are placed on the γ-A^{'} kinetic mixing strength. The promptlike A^{'} search explores the mass region from near the dimuon threshold up to 70 GeV and places the most stringent constraints to date on dark photons with 214<m(A^{'})≲740  MeV and 10.6<m(A^{'})≲30  GeV. The search for long-lived A^{'}→μ^{+}μ^{-} decays places world-leading constraints on low-mass dark photons with lifetimes O(1)  ps.
