  The reaction p(@3.5\,GeV)+p -> p+\Lambda + K^+ can be studied to search for
the existence of kaonic bound states like ppK^- leading to this final state.
This effort has been motivated by the assumption that in p+p collisions the
\Lambda(1405) resonance can act as a doorway to the formation of the kaonic
bound states. The status of this analysis within the HADES collaboration, with
particular emphasis on the comparison to simulations, is shown in this work and
the deviation method utilized by the DISTO collaboration in a similar analysis
is discussed. The outcome suggests the employment of a partial wave analysis to
disentangle the different contributions to the measured pK^+\Lambda final
state.
