Abstract
The production of (pseudoscalar) mesons in proton deuteron fusion to a ${}^3\textrm{He}$ nucleus and a mesonic system $X$ has been a topic of active research for almost 30 years. Nonetheless, it still poses some open questions, most notably in the $\textrm{pd } (\textrm{dp}) \rightarrow {}^3\textrm{He}\eta$ and $\textrm{pd } (\textrm{dp}) \rightarrow {}^3\textrm{He}(\pi\pi)^{0}$ channels. The WASA-at-COSY Collaboration performed a new measurement in 2014 using the Wide Angle Shower Apparatus located inside the Cooler Synchrotron of the Forschungszentrum Jülich at 15 different beam momenta between $p_p = 1.60\; \textrm{GeV/c}$ and $p_p = 1.74\; \textrm{GeV/c}$ aiming to address some of these open questions. During the conference, recent preliminary results of the analysis of this new dataset were presented along with an outlook of the possibility this new dataset presents for the future.
