DESCRIPTION:Millicharged particles (mCPs) represent one of the most minima
 l extensions of\nthe Standard Model\, and\, until recently\, were surprisi
 ngly poorly constrained for masses greater than roughly ~100 MeV. Recent p
 roposals to discover mCPs have focussed on intense proton beams which resu
 lt in meson cascades that can provide extremely large fluxes of mCPs\; thi
 s "beam" of mCPs can\, in turn\, be detected at downstream detectors.\n\nI
 n this talk I will discuss how cosmic rays can act as a proton beam in the
 ir own right with the upper atmosphere serving as a fixed (and very thick)
  target. I will explain how\, by combining well understood meson productio
 n cross sections\, one can calculate the flux of mCPs from primary pp coll
 isions. We find competitive constraints with accelerator based experiments
 \, and find that our results can limit a recently proposed strongly-intera
 cting dark matter "window".\n\nhttps://indico.ific.uv.es/event/4126/
