Title: Precision Measurement of the $(e^{+} + e^{-})$ Flux in Primary Cosmic Rays from 0.5 GeV to 1 TeV with the Alpha Magnetic Spectrometer on the International Space Station

Abstract

We present a measurement of the cosmic ray (e⁺+e^-) flux in the range 0.5 GeV to 1 TeV based on the analysis of 10.6 million (e⁺+e^-) events collected by AMS. The statistics and the resolution of AMS provide a precision measurement of the flux. The flux is smooth and reveals new and distinct information. Above 30.2 GeV, the flux can be described by a single power law with a spectral index γ= -3.170 ± 0.008(stat+syst) ± 0.008(energy scale).

  abstractNote = {We present a measurement of the cosmic ray (e++e-) flux in the range 0.5 GeV to 1 TeV based on the analysis of 10.6 million (e++e-) events collected by AMS. The statistics and the resolution of AMS provide a precision measurement of the flux. The flux is smooth and reveals new and distinct information. Above 30.2 GeV, the flux can be described by a single power law with a spectral index γ= -3.170 ± 0.008(stat+syst) ± 0.008(energy scale).},

Evidence for $e^{+} e^{-} \to γ η_{c} (1 S)$ at center-of-mass energies between 4.01 and 4.60 GeV

Journal Article Ablikim, M. ; Achasov, M. N. ; Ahmed, S. ; ... - Physical Review D

In this paper, we present first evidence for the process e⁺e^- → γη_c(1S) at six center-of-mass energies between 4.01 and 4.60 GeV using data collected by the BESIII experiment operating at BEPCII. We measure the Born cross section at each energy using a combination of twelve η_c(1S) decay channels. We also combine all six energies under various assumptions for the energy-dependence of the cross section. Finally, if the process is assumed to proceed via the Y (4260), we measure a peak Born cross section σ_peak (e⁺e^- → γη_c(1S)) = 2.11 ± 0.49(stat.) ± 0.36(syst.) pb with a statistical significance ofmore » 4.2σ.« less

Using an e⁺e^- collision data sample of 2.93 fb^-1 collected at a center-of-mass energy of 3.773 GeV by the BESIII detector at BEPCII, we report the observation of D⁰ → a₀(980)^-e⁺ν_e and evidence for D⁺ → a₀(980)⁰e⁺ν_e with significances of 6.4σ and 2.9σ, respectively.

Cross section measurements of $e^{+} e^{-} \to ω χ_{c 0}$ from $\sqrt{s} = 4.178$ to 4.278 GeV

Journal Article Ablikim, M. ; Achasov, M. N. ; Adlarson, P. ; ... - Physical Review. D.

The cross section of the process e⁺e^– → ωχ_c0 is measured at center-of-mass energies from √s = 4.178 to 4.278 GeV using a data sample of 7 fb^–1 collected with the BESIII detector operating at the BEPCII storage ring. The dependence of the cross section on √s shows a resonant structure with mass of (4218.5 ± 1.6(stat) ± 4.0(syst)) MeV/c² and width of (28.2 ± 3.9(stat) ± 1.6(syst)) MeV, respectively. This observation confirms and improves upon the result of a previous study. The angular distribution of the e⁺e^– → ωχ_c0 process is extracted for the first time.
