Precise direct cosmic-ray (CR) measurements provide an important probe to study the energetic particle sources in our Galaxy, and interstellar environment through which these particles propagate. Uncertainties on hadronic models, ion-nucleon cross sections particular, are currently limiting factor towards obtaining more accurate CR ion flux with calorimetric space-based experiments. We present energy-dependent measurement of inelastic section protons helium-4 nuclei (alpha particles) a...
Secondary cosmic ray fluxes are important probes of the propagation and interaction high-energy particles in Galaxy. Recent measurements primary secondary nuclei have revealed unexpected spectral features that demand a deeper understanding. In this work we report direct measurement boron spectrum from 10 TeV/n to 8 with eight years data collected by Dark Matter Particle Explorer (DAMPE) mission. The measured shows an evident hardening at $182\pm24$ GeV/n power index $\gamma_1 = 3.02 \pm...
More than a century after the performance of oil drop experiment, possible existence fractionally charged particles FCP still remains unsettled. The search for FCPs is crucial some extensions Standard Model in particle physics. Most previously conducted searches cosmic rays were based on experiments underground or at high altitudes. However, there have been few carried out orbit other AMS-01 flown by space shuttle and BESS balloon top atmosphere. In this study, we conduct an on-orbit data...
