1. Observation of ψ(3686)pp¯ϕ / Ablikim, M. ; Achasov, M. N. ; Adlarson, P. ; Ahmed, S. ; et al
Using a data sample of 4.48×108 ψ(3686) events collected with the BESIII detector, we present a first observation of ψ(3686)pp¯ϕ, and we measure its branching fraction to be [6.06±0.38(stat)±0.48(syst)]×106. [...]

10. Search for C violation in the decay η  →  π 0 e + e − with WASA-at-COSY / Adlarson, P. ; Augustyniak, W. ; Bardan, W. ; Bashkanov, M. ; et al
We report on the search for the rare decay η→π0e+e− which is of interest to study C violation in the electromagnetic interaction which would indicate contributions from physics beyond the Standard Model, since the allowed decay via a two-photon intermediate state is strongly suppressed. [...]
