Observation of Complex Time Structures in the Cosmic-Ray Electron and Positron Fluxes with the Alpha Magnetic Spectrometer on the International Space Station
We present high-statistics, precision measurements of the detailed time and energy dependence of the primary cosmic-ray electron flux and positron flux over 79 Bartels rotations from May 2011 to May 2017 in the energy range from 1 to 50 GeV. For the first time, the charge-sign dependent modulation d...

| description | We present high-statistics, precision measurements of the detailed time and energy dependence of the primary cosmic-ray electron flux and positron flux over 79 Bartels rotations from May 2011 to May 2017 in the energy range from 1 to 50 GeV. For the first time, the charge-sign dependent modulation during solar maximum has been investigated in detail by leptons alone. Based on 23.5×10^{6} events, we report the observation of short-term structures on the timescale of months coincident in both the electron flux and the positron flux. These structures are not visible in the e^{+}/e^{-} flux ratio. The precision measurements across the solar polarity reversal show that the ratio exhibits a smooth transition over 830±30 days from one value to another. The midpoint of the transition shows an energy dependent delay relative to the reversal and changes by 260±30 days from 1 to 6 GeV. |

For the first time, the charge-sign dependent modulation during solar maximum has been investigated in detail by leptons alone. Based on 23.5×10^{6} events, we report the observation of short-term structures on the timescale of months coincident in both the electron flux and the positron flux. These structures are not visible in the e^{+}/e^{-} flux ratio. The precision measurements across the solar polarity reversal show that the ratio exhibits a smooth transition over 830±30 days from one value to another. The midpoint of the transition shows an energy dependent delay relative to the reversal and changes by 260±30 days from 1 to 6 GeV.</abstract><cop>United States</cop><pub>American Physical Society</pub><pmid>30118287</pmid><doi>10.1103/PhysRevLett.121.051102</doi><tpages>1</tpages><orcidid>https://orcid.org/0000-0003-1670-2966</orcidid><orcidid>https://orcid.org/0000-0002-9394-2392</orcidid><orcidid>https://orcid.org/0000-0002-5331-0606</orcidid><orcidid>https://orcid.org/0000-0002-5172-0783</orcidid><orcidid>https://orcid.org/0000-0003-1841-9486</orcidid><orcidid>https://orcid.org/0000-0002-1103-130X</orcidid><orcidid>https://orcid.org/0000-0001-6725-5399</orcidid><orcidid>https://orcid.org/0009-0004-7563-4144</orcidid><orcidid>https://orcid.org/0000-0003-4365-3282</orcidid><orcidid>https://orcid.org/0000-0002-1558-4948</orcidid><oa>free_for_read</oa></addata></record> |
