Abstract
Gamma-ray bursts are a possible site of hadronic acceleration, thus neutrinos are expected in correspondence of a GRB event. The brightest GRB observed between 2008 and 2013 (GRB080916C, GRB110918A, GRB130427A and GRB130505A) have been investigated using the data of the ANTARES high energy neutrino telescope. In this paper two of most promising models of the GRB neutrino emission will be studied: the internal shock model and the photospheric model. No muons have been measured in space and time correlation with the selected GRBs and upper limits at 90% C.L. on the expected neutrino fluxes have been derived. This measure allows also setting constraints on some parameters used in the modeling of the neutrino flux: the bulk Lorentz factor of the jet Г and the baryon loading f p .

The ANTARES detector (Astronomy with a Neutrino Telescope and Abyss environmental RESearch) is the largest neutrino telescope currently in operation in the Northern Hemisphere and the first operating in sea water. It is a three dimensional array of photo-multiplier tubes (PMTs), in which neutrinos are detected through the Cherenkov radiation induced by ultra-relativistic particles created in a neutrino interaction
The main goal of the ANTARES telescope is the detection of high energy cosmic neutrinos and in particular the identification of point-like sources
Summary
The ANTARES detector (Astronomy with a Neutrino Telescope and Abyss environmental RESearch) is the largest neutrino telescope currently in operation in the Northern Hemisphere and the first operating in sea water. It is a three dimensional array of photo-multiplier tubes (PMTs), in which neutrinos are detected through the Cherenkov radiation induced by ultra-relativistic particles created in a neutrino interaction. Several gamma ray burst models have been proposed in the last few years, the most promising of which are the internal shock [1] and photospheric models [3]
