Sensitivity of the ANTARES neutrino telescope to atmospheric neutrino oscillation parameters

A new analysis, aimed at improving the current ANTARES measurement of the atmospheric neu-
trino oscillation parameters, is presented in these proceedings. Two different track reconstruction
procedures are combined in order to increase the sensitivity. Furthermore, a novel method to
estimate the neutrino energy is applied. A complete 3-flavour description of the oscillation prob-
ability including matter effects in the Earth is used. By performing a two-dimensional fit of the
event rate as a function of reconstructed energy and zenith angle, expectations on the sensitivity to
the oscillation parameters are derived. Using the same analysis chain, a study on the ANTARES
sensitivity to sterile neutrinos is performed.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
