Search for GRB counterparts using the ARGO-YBJ experiment in shower mode

摘要：

In this paper,the eriective area of the ARGo-YBJ experiment to detect the gamma rays with energy range from 10GeV to 1 TeV for different incident zenith angles(0,10,20,30,40 degrees)is given respectively．The optimal event selectionsto search for GRB counterparts with difrerent cutoff energy models(Ecut=100 GeV and 1 TeV)are studied．Using theseselections and their corresponding angular resolutions the searches are done within two hours around the GRB trigger timevia different time windows．Finally,the result for the 20 GRBs in the field of view of ARGO between July 2006 and July 2008is presented,and the fluence upper limit for each GRB is set at 99％confidence level．
