Search for TeV counterparts of BATSE gamma ray bursts with the HEGRA air shower arrays

Twenty nine gamma ray bursts recorded between 1993 and 1995 with the BATSE instrument were searched for an emission in the energy range above 13 TeV. The method used the data of the scintillator array and the wide angle Cherenkov counter array AIROBICC of the HEGRA experiment. As a novelty not only coincident emission but also short and long time emission in the hours before and after the BATSE detection were searched for. Weak evidence was found for coincident and for precursor short time emission.
