DESCRIPTION:Speakers: Ke Fang (University of Chicago)\nFast-spinning newbo
 rn pulsars are promising sources of ultrahigh energy cosmic rays (UHECRs).
  With proper injection abundances\, integrated cosmic rays from the extrag
 alactic pulsar population can match UHE observation in all aspects - energ
 y spectrum\, chemical composition\, and anisotropy. High-energy neutrinos 
 would be produced unavoidably\, when accelerated UHECRs travel through the
  supernova envelope surrounding the pulsar. In this talk\,  we will invest
 igate this neutrino production process\, including the hadronuclear intera
 ction between cosmic rays and the background\, and possible suppression du
 e to the pion interaction. We will report the spectrum\, flux and flavor r
 atio of  the high-energy neutrinos from pulsars\, and compare their detect
 ability to sensitivities of current and future experiments. Finally\, we w
 ill discuss our model dependence on the source emissivity\,  the distribut
 ion of pulsar population at birth\, as well as the injection composition o
 f cosmic rays.\n\nhttps://indico.icrr.u-tokyo.ac.jp/event/23/contributions
