Bearing holographic dark energy hypothesis in mind, the ability of vacuum energy in
describing the current accelerated universe is studied in the framework of Rastall theory.
Here, in addition to the ordinary approach in which it is expected that this energy
plays the role of dark energy, we also address a new approach where the sum of this
energy and Rastall term is responsible for the current accelerated universe. We also
investigate the cosmological outcomes of using Tsallis entropy in quantifying the energy
of elds in vacuum for both mentioned approaches. The implications of considering an
interaction between the various segments of cosmic uid have been addressed in each
studied cases. The normalized Hubble parameter for the models have also been plotted
and compared that with the H(z) data consisting of 41 data points in the redshift range
of 0:07 z 2:36.
