Modeling of helium flux in cosmic rays with Alpha Magnetic Spectrometer measurements

摘要

Discrete quantum kinetic model together with the introduction of Pauli-blocking parameter and an orientation parameter are adopted to firstly obtain the dispersion relations of plane waves propagating in dilute Bose gases. With the diffusion mode of the dispersion relations of plane waves propagating in dilute Bose gases as well as the acoustic analog we can study the helium (boson) flux in cosmic rays considering the precision measurement with the Alpha Magnetic Spectrometer (AMS) on the International Space Station (ISS). Our approximately numerical as well as analytic results match qualitatively quite well with those data measured with the AMS on the ISS.
