 \, Riccardo Biondi\, Izabela Anna Kochanek (Istituto Nazionale di Fisica N
 ucleare)\n\nIt is commonly accepted that high energy cosmic rays up to 100
  EeV can be produced in catastrophic astrophysical processes. However the 
 source of a few observed events with higher energies remains mysterious. W
 e propose that they may originate from decay or annihilation of ultra heav
 y particles of dark matter. Such particles naturally appear in some models
  of modified gravity related  to Starobinsky inflation. Applications to t
 he high energy neutrino events observed at IceCube are also discussed.\n--
