Gamma-ray bursts (GRB) are the most energetic transient sources observed in the Universe. They are supposed to be produced by the emission of an inhomogeneous relativistic jet in which energy dissipation occurs via internal shocks. In these shocks, particles as electrons and protons could be accelerated at very high energies via Fermi acceleration processes. Thus, GRB are promising candidates to be cosmic accelerators of the very high energy cosmic rays. However, since cosmic-rays are deviated by magnetic fields and interact with matter and also because GRBs are mostly located at high redshift, it is impossible to directly observe an association between a GRB and a cosmic ray signal. High-energy neutrinos are proxies commonly used to directly probe such association because they are created by photohadronic interactions in the GRB jets up to very high energies and then propagate straight towards the observer. ANTARES is the largest neutrino telescope in the Northern Hemisphere. In this presentation, the GRB analysis done with four years of ANTARES data to search for a GRB neutrino signal will be presented. An individual study of GRB130427A, one of the most energetic and nearby burst, will also be shown. At last, thanks to the ANTARES results constraints on the physics of GRB jets have been derived for few bursts.
