First Determination of the Spin-Parity of Ξ_{c}(3055)^{+,0} Baryons.

The Ξ_{b}^{0(-)}→Ξ_{c}(3055)^{+(0)}(→D^{+(0)}Λ)π^{-} decay chains are observed, and the spin-parity of Ξ_{c}(3055)^{+(0)} baryons is determined for the first time. The measurement is performed using proton-proton collision data at a center-of-mass energy of sqrt[s]=13  TeV, corresponding to an integrated luminosity of 5.4  fb^{-1}, recorded by the LHCb experiment between 2016 and 2018.

Ask, do not tell: consulting a patient advisory board to understand unmet needs of patients with GVHD in Europe.

Graft-versus-host disease (GVHD) is a complication of hematopoietic cell transplantation (HCT) that has a low chance of complete remission and a substantial effect on morbidity and mortality. To better understand how to improve the field of GVHD research, management, and care, the cGVHD Eurograft Initiative organised a European community advisory board of patient advocates, with the assistance of the Lymphoma Coalition, to identify unmet needs. We present the results of this project in this Viewpoint, which identify unmet GVHD needs from the patient advocates' perspectives and provide five key actionable themes to improve GVHD management and care.

Measurement of the Branching Fraction Ratios R(D^{+}) and R(D^{*+}) Using Muonic τ Decays.

The branching fraction ratios of B[over ¯]^{0}→D^{+}τ^{-}ν[over ¯]_{τ} and B[over ¯]^{0}→D^{*+}τ^{-}ν[over ¯]_{τ} decays are measured with respect to their muonic counterparts, using a data sample corresponding to an integrated luminosity of 2.0  fb^{-1} collected by the LHCb experiment in proton-proton collisions at sqrt[s]=13  TeV. The reconstructed final states are formed by combining D^{+} mesons with τ^{-}→μ^{-}ν[over ¯]_{μ}ν_{τ} candidates, where the D^{+} is reconstructed via the D^{+}→K^{-}π^{+}π^{+} decay.

Observation of Exotic J/ψϕ Resonant Structure in Diffractive Processes in Proton-Proton Collisions.

The first study of J/ψϕ production in diffractive processes in proton-proton collisions is presented. The study is based on an LHCb dataset recorded at center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 5  fb^{-1}. The data disfavor a nonresonant J/ψϕ production but are consistent with a resonant model including several resonant states observed previously only in B^{+}→J/ψϕK^{+} decays.

Draft genome of CV167, a bacteriocinogenic strain isolated from raw milk in Minas Gerais, Brazil.

Here, we describe the draft genome sequence of CV167, a strain isolated from raw milk in Brazil that exhibits antimicrobial activity against various pathogens. The draft genome has a completeness index of 99.3%, spans 2,736,418 base pairs, has a guanine-cytosine content of 37.
