Measurements of Absolute Branching Fractions of Fourteen Exclusive Hadronic D Decays to η

Mikhail N. Achasov, P. Adlarson, S. Ahmed, M. Albrecht et autres

Using $2.93\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of ${e}^{+}{e}^{\ensuremath{-}}$ collision data taken at a center-of-mass energy of 3.773 GeV with the BESIII detector, we report the first measurements of the absolute branching fractions of 14 hadronic ${D}^{0(+)}$ decays to exclusive final states with an $\ensuremath{\eta}$, …

Measurement of the Cross Section for e+e−→Ξ−Ξ¯+ and Observation of an Excited Ξ Baryon

M. N. Achasov, P. Adlarson, S. Ahmed, M. Albrecht et autres

Using a total of $11.0\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of ${e}^{+}{e}^{\ensuremath{-}}$ collision data with center-of-mass energies between 4.009 and 4.6 GeV and collected with the BESIII detector at BEPCII, we measure fifteen exclusive cross sections and effective form factors for the process ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{\mathrm{\ensuremath{\Xi}}}^{\ensuremath{-}}{\overline{\mathrm{\ensuremath{\Xi}}}}^{+}$ by …

Measurements of the Mass and Width of the ηc Using the Decay ψ(3686)→γηc

M. N. Achasov, Diego Alberto, D. Ambrose, F. F. An et autres

The mass and width of the lowest-lying $S$-wave spin singlet charmonium state, the ${\ensuremath{\eta}}_{c}$, are measured using a data sample of $1.06\ifmmode\times\else\texttimes\fi{}{10}^{8}$ $\ensuremath{\psi}(3686)$ decays collected with the BESIII detector at the BEPCII storage ring. We use a model that incorporates full interference …

Subtraction of beam-associated background in R measurement

鄢文标, X. Cai, 迟少鹏, 黄光顺 et autres

Using R scan data collected at BES II detector, we study the character of beam-associated background. We use the method of f factor and the fitting of event vertices to subtract the residual beam-associated background. The difference between the R values obtained …
