Direct detection of a break in the teraelectronvolt cosmic-ray spectrum of electrons and positrons

G. Ambrosi, +157 more
- 29 Nov 2017 - 
TL;DR: The direct detection of a spectral break at about 0.9 teraelectronvolts confirms the evidence found by previous indirect measurements, clarifies the behaviour of the CRE spectrum at energies above 1 terAElectronvolt and sheds light on the physical origin of the sub-teraelectronsvolt CREs.
Journal ArticleDOI

The DArk Matter Particle Explorer mission

Jin Chang, +176 more
TL;DR: The DArk Matter Particle Explorer (DAMPE) as mentioned in this paper, one of the four scientific space science missions within the framework of the Strategic Pioneer Program on Space Science of the Chinese Academy of Sciences, was successfully launched on December 17th, 2015 from the Jiuquan Satellite Launch Center.
Journal ArticleDOI

Measurement of the $\mathrm e^+\mathrm e^-\rightarrow\mathrm\pi^+\mathrm\pi^-$ Cross Section between 600 and 900 MeV Using Initial State Radiation

M. Ablikim, +400 more
- 29 Jul 2015 - 
TL;DR: In this paper, the authors extracted the pion form factor of the measured cross section in the energy range between 600 and 900 MeV, exploiting the method of initial state radiation.
Journal ArticleDOI

Measurement of the cosmic-ray proton spectrum from 40 GeV to 100 TeV with the DAMPE satellite

Q. An, +175 more
- 01 Sep 2019 - 
TL;DR: The measurement of the cosmic ray proton fluxes with kinetic energies from 40 GeV to 100 TeV, with 2 1/2 years of data recorded by the DArk Matter Particle Explorer (DAMPE), suggests the existence of a new spectral feature of cosmic rays at energies lower than the so-called knee and sheds new light on the origin of Galactic cosmic rays.
Journal ArticleDOI

Observation of a Near-Threshold Structure in the K+ Recoil-Mass Spectra in e+e- →k+ (Ds- D∗0+ Ds∗- D0)

M. Ablikim, +495 more
TL;DR: This is the first candidate for a charged hidden-charm tetraquark with strangeness, decaying into D_{s}^{-}D^{*0} and D-D^{0}.
