Evidence for a New Structure in the J/ψp and J/ψ(anti-)p Systems in B0s→J/ψp(anti-)p Decays

2022 · ARTICLE · en

An amplitude analysis of flavor-untagged B0s→J/ψp(anti-)p decays is performed using a sample of 797±31 decays reconstructed with the LHCb detector. The data, collected in proton-proton collisions between 2011 and 2018, correspond to an integrated luminosity of 9 fb−1. Evidence for a new structure in the J/ψp and J/ψ(anti-)p systems with a mass of 4337+7−4 +2−2 MeV and a width of 29+26−12 +14−14 MeV is found, where the first uncertainty is statistical and the second systematic, with a significance in the range of 3.1 to 3.7σ, depending on the assigned JP hypothesis.

J/ψ photoproduction in Pb-Pb peripheral collisions at √s = 5TeV

2022 · ARTICLE · en

The photo-production of J/ψ mesons at low transverse momentum is studied in peripheral lead-lead collisions collected by the LHCb experiment at a centre-of-mass energy per nucleon pair of 5 TeV, corresponding to an integrated luminosity of 210 μb−1. The J/ψ candidates are reconstructed through the prompt decay into two muons of opposite charge in the rapidity region of 2.0

Measurement of the Nuclear Modification Factor and Prompt Charged Particle Production in p-Pb and pp Collisions at √sNN=5 TeV

2022 · ARTICLE · en

The production of prompt charged particles in proton-lead collisions and in proton-proton collisions at the nucleon-nucleon centre-of-mass energy √s=5TeV is studied at LHCb as a function of pseudorapidity (η) and transverse momentum (pT) with respect to the proton beam direction. The nuclear modification factor for charged particles is determined as a function of η between −4.8

Observation of the doubly charmed baryon decay Ξ++ → Ξ′+π+

2022 · ARTICLE · en

The Ξ++ → Ξ′+π+ decay is observed using proton-proton collisions collected by the LHCb experiment at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 5.4fb−1. The Ξ++ → Ξ′+π+ decay is reconstructed partially, where the photon from the Ξ′+ → Ξ+γ decay is not reconstructed and the pK−π+ final state of the Ξ+ baryon is employed. The Ξ++ → Ξ′+π+ branching fraction relative to that of the Ξ++ → Ξ+π+ decay is measured to be 1.41 ± 0.17 ± 0.10, where the first uncertainty is statistical and the second systematic.

Measurement of prompt charged-particle production in pp collisions at s√ = 13 TeV

2022 · ARTICLE · en

The differential cross-section of prompt inclusive production of long-lived charged particles in proton-proton collisions is measured using a data sample recorded by the LHCb experiment at a centre-of-mass energy of s√s = 13 TeV. The data sample, collected with an unbiased trigger, corresponds to an integrated luminosity of 5.4 nb−1. The differential cross-section is measured as a function of transverse momentum and pseudorapidity in the ranges pT ∈ [80, 10 000) MeV/c and η ∈ [2.0, 4.8) and is determined separately for positively and negatively charged particles. The results are compared with predictions from various hadronic-interaction models.

Measurement of the photon polarization in Λ0b→Λγ decays

2022 · ARTICLE · en

The photon polarization in b→sγ transitions is measured for the first time in radiative b -baryon decays exploiting the unique spin structure of Λ0b→Λγ decays. A data sample corresponding to an integrated luminosity of 6 fb−1 collected by the LHCb experiment in pp collisions at a center-of-mass energy of 13 TeV is used. The photon polarization is measured to be αγ=0.82+0.17+0.04−0.26−0.13, where the first uncertainty is statistical and the second systematic. This result is in agreement with the Standard Model prediction and previous measurements in b -meson decays. Charge-parity breaking effects are studied for the first time in this observable and found to be consistent with CP symmetry.

Observation of an exotic narrow doubly charmed tetraquark

2022 · ARTICLE · en

Conventional, hadronic matter consists of baryons and mesons made of three quarks and a quark–antiquark pair, respectively1,2. Here, we report the observation of a hadronic state containing four quarks in the Large Hadron Collider beauty experiment. This so-called tetraquark contains two charm quarks, a uu and a dd quark. This exotic state has a mass of approximately 3,875 MeV and manifests as a narrow peak in the mass spectrum of D0D0π+ mesons just below the D*+D0 mass threshold. The near-threshold mass together with the narrow width reveals the resonance nature of the state.

Observation of Two New Excited Ξ0b States Decaying to Λ0bK−π+

2022 · ARTICLE · en

Two narrow resonant states are observed in the Λ0bK−π+ mass spectrum using a data sample of proton-proton collisions at a center-of-mass energy of 13 TeV, collected by the LHCb experiment and corresponding to an integrated luminosity of 6 fb−1. The minimal quark content of the Λ0bK−π+ system indicates that these are excited Ξ0b baryons. The masses of the Ξb(6327)0 and Ξb(6333)0 states are m[Ξb(6327)0]=6327.28+0.23−0.21±0.12±0.24 and m[Ξb(6333)0]=6332.69+0.17−0.18±0.03±0.22 MeV, respectively, with a mass splitting of Δm=5.41+0.26−0.27±0.12 MeV, where the uncertainties are statistical, systematic, and due to the Λ0b mass measurement. The measured natural widths of these states are consistent with zero, with upper limits of Γ[Ξb(6327)0]

Search for massive long-lived particles decaying semileptonically at s√=13TeV

2022 · ARTICLE · en

A search is performed for massive long-lived particles (LLPs) decaying semileptonically into a muon and two quarks. Two kinds of LLP production processes were considered. In the first, a Higgs-like boson with mass from 30 to 200\,GeV\!/c2\,GeV\!/c2 is produced by gluon fusion and decays into two LLPs. The analysis covers LLP mass values from 10\,GeV\!/c2\,GeV\!/c2 up to about one half the Higgs-like boson mass. The second LLP production mode is directly from quark interactions, with LLP masses from 10 to 90\,GeV\!/c2\,GeV\!/c2. The LLP lifetimes considered range from 5 to 200 ps. This study uses LHCb data collected from proton-proton collisions at s√=13\,TeVs=13\,TeV, corresponding to an integrated luminosity of 5.4\,fb−1\,fb−1. No evidence of these long-lived states has been observed, and upper limits on the production cross-section times branching ratio have been set for each model considered.

Searches for rare B0s and B0 decays into four muons

2022 · ARTICLE · en

Searches for rare B0sBs0 and B0 decays into four muons are performed using proton-proton collision data recorded by the LHCb experiment, corresponding to an integrated luminosity of 9 fb−1. Direct decays and decays via light scalar and J/ψ resonances are considered. No evidence for the six decays searched for is found and upper limits at the 95% confidence level on their branching fractions ranging between 1.8 × 10−10 and 2.6 × 10−9 are set.
