Study of the f0(980) and f0(500) Scalar Mesons through the Decay Ds+→π+π−e+νe

М. Н. Ачасов, P. Adlarson, R. Aliberti, A. Amoroso et autres

Using e^{+}e^{-} collision data corresponding to an integrated luminosity of 7.33 fb^{-1} recorded by the BESIII detector at center-of-mass energies between 4.128 and 4.226 GeV, we present an analysis of the decay D_{s}^{+}→π^{+}π^{-}e^{+}ν_{e}, where the D_{s}^{+} is produced via the process e^{+}e^{-}→D_{s}^{*±}D_{s}^{∓}. …

Observation of Significant Flavor-SU(3) Breaking in the Kaon Wave Function at 12<Q2<25 GeV2 and Discovery of the Charmless Decay ψ(3770)→KS0KL0

М. Н. Ачасов, P. Adlarson, X. Ai, R. Aliberti et autres

We present cross sections for the reaction e^{+}e^{-}→K_{S}^{0}K_{L}^{0} at center-of-mass energies ranging from 3.51 to 4.95 GeV using data samples collected in the BESIII experiment, corresponding to a total integrated luminosity of 26.5 fb^{-1}. The ratio of neutral-to-charged kaon form factors at …

First Measurement of the Decay Asymmetry in the Pure W -Boson-Exchange Decay Λc+→Ξ0K+

М. Н. Ачасов, P. Adlarson, X. Ai, R. Aliberti et autres

Based on 4.4 fb^{-1} of e^{+}e^{-} annihilation data collected at the center-of-mass energies between 4.60 and 4.70 GeV with the BESIII detector at the BEPCII collider, the pure W-boson-exchange decay Λ_{c}^{+}→Ξ^{0}K^{+} is studied with a full angular analysis. The corresponding decay asymmetry …

Measurement of Energy-Dependent Pair-Production Cross Section and Electromagnetic Form Factors of a Charmed Baryon

М. Н. Ачасов, P. Adlarson, X. Ai, R. Aliberti et autres

We study the process ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{\mathrm{\ensuremath{\Lambda}}}_{c}^{+}{\overline{\mathrm{\ensuremath{\Lambda}}}}_{c}^{\ensuremath{-}}$ at twelve center-of-mass energies from 4.6119 to 4.9509 GeV using data samples collected by the BESIII detector at the BEPCII collider. The Born cross sections and effective form factors ($|{G}_{\mathrm{eff}}|$) are determined with unprecedented precision after combining …

[Depression and anxiety in patients with psoriatic arthritis: Prevalence and associated factors].

Yan Geng, Zhaolu Song, X H Zhang, Xiulian Deng et autres

OBJECTIVE: To determine the prevalence of depression and anxiety in patients with psoriatic arthritis (PsA), to investigate whether there is a difference in the prevalence of depression and anxiety between PsA and rheumatoid arthritis (RA) patients and to identify associated risk factors …
