Description

Abstract: The origin of the Ultra-High Energy Cosmic Rays (UHECRs) is still unknown. Gamma-Ray Bursts (GRBs) are generally presented as possible candidates to host progenitors producing such UHECRs. However, the exact physical processes underlying GRBs are yet not fully understood. If GRBs are (partly) responsible for the observed UHECRs, they have to contain a hadronic component, and consequently high-energy neutrinos must also be produced. In this case, large scale neutrino observatories on Earth, such as the cubic kilometer IceCube Neutrino Observatory located at the South Pole, should be able to detect them. We will present a search method based on two separate datasets: the long ($T_{90}$ > 2 sec) and short ($T_{90}$ < 2 sec) GRBs. They will be treated separately in order to obtain the best possible sensitivity as the commonly accepted picture is that long GRBs and short GRBs have a different inner engine Our studies will be based on different event selections and specific statistical methods. The latter include a newly developped spatial and a time spectral analysis of which the details will be discussed.
