\panda\ at FAIR will address the physics of strangeness in nuclei by several novel and unique measurements. These studies are only made possible by the one-of-a-kind combination of the stored antiproton beam at FAIR and the modular \panda\ detector which will be complemented by a germanium detector array. The latter was made available by a cooperation with the NUSTAR collaboration. \begin{itemize} \item \panda\ also offers the unique possibility to search for X-rays from very heavy hyperatoms such as e.g. $\Xi^-$-$^{208}$Pb. This will complement experiments at J-PARC which attempt to measure X-rays in light and (possibly) medium-heavy nuclei by the J-PARC E03 and E07 experiments. The measurement at \panda\ will allow to constrain the real and imaginary potential of $\Xi^-$ hyperons in the neutron skin of the lead nucleus. \item \panda\ will extend the studies on double hypernuclei by performing for the first time high resolution $\gamma$-spectroscopy of these nuclei. Thus, \Panda\ complements measurements of ground state masses of double hypernuclei in emulsions at J-PARC conducted by the E07 Collaboration \cite{E07-proposal,doi:10.1142/9789814618229_0025} or the production of excited resonant states in heavy ion reactions which may, for example, be explored in future by the CBM Collaboration. Together, these measurements will provide a as yet unrivaled information on the structure of double $\Lambda\Lambda$ hypernuclei. \item Furthermore, the exclusive production of hyperon-antihyperon pairs close to their production threshold in $\Pap$ - nucleus collisions offers a unique and hitherto unexplored opportunity to elucidate the behaviour of antihyperons in cold nuclei which is intimately related to the short-range part of the baryonic interaction. \end{itemize} In all these studies, the production of low momentum {\PagL} within nuclei or slow $\Xi^-$ hyperons which can eventually be stopped in a secondary target material play an essential role.

The PANDA experiment will be one of the pillars of the new Facility for Antiproton and Ion Research (FAIR), which is currently under construction in Darmstadt, Germany. PANDA will be a fixed-target experiment which will allow the study of non-perturbative phenomena of the strong interaction. These will be probed in antiproton-proton collisions in the momentum range of 1.5 - 15 GeV/c. Within the PANDA physics program, strangeness production will be addressed through pbar p - > Ybar Y processes. Measurements of the pbar p-> Sigmabar Lambda channel for its comparison with the existing data of the Lambdabar Lambda channel are highly encouraged to study the role of isospin symmetry in hadron production dynamics. This work consists on a simulation study focusing on the feasibility of measuring the pbar p -> Sigmabar Lambda channel at PANDA.
