list of known planets around M dwarfs presented by @bonfils13. Though, close to this part of the parameter space there are planets GJ 317b and GJ 676Ab. Among the planetary transit candidates with more than one transit announced by the [*Kepler*]{} mission, the longest orbital periods are around $500~{\rm d}$ [@borucki11; @batalha13], i.e., much shorter than the expected $5.9~{\rm yr}$. Moreover, the probability of the proper orbit alignment is very low; hence, it is very difficult for transit surveys to find planets with $5.9~{\rm yr}$ periods if they exist. Also high spatial resolution imaging is not an efficient way of finding such planets, as they are too close to the parent star. Thus, gravitational microlensing seems to be the most efficient method in discovering super-Jupiter planets around dwarf stars [@gaudi12]. The relatively large mass ratio $q$ makes both central and planetary caustics large, as their size is proportional to $q$ and $q^{1/2}$, respectively [@gould92; @griest98; @chung05; @han06]. This makes discovering such planets more feasible, because the probability that the background source would pass close enough to the caustic is higher.

In fact, microlensing has already been successful in discovering massive planets around M dwarfs. @dong09a analyzed all available data, including
