Ultrarelativistic magnetic monopole search with the ANITA-II balloon-borne radio interferometer

We have conducted a search for extended energy deposition trails left by ultrarelativistic magnetic monopoles interacting in Antarctic ice. The nonobservation of any satisfactory candidates in the 31 days of accumulated ANITA-II (Antarctic Impulsive Transient Antenna) flight data results in an upper...

Description
Summary:We have conducted a search for extended energy deposition trails left by ultrarelativistic magnetic monopoles interacting in Antarctic ice. The nonobservation of any satisfactory candidates in the 31 days of accumulated ANITA-II (Antarctic Impulsive Transient Antenna) flight data results in an upper limit on the diffuse flux of relativistic monopoles. We obtain a 90% C.L. limit of order 10(-19) (cm(2) s sr)(-1) for values of Lorentz factor, gamma, 10(10) <= at the anticipated energy E-tot = 10(16) GeV. This bound is stronger than all previously published experimental limits for this kinematic range.
