“…The possible extension of the present work can be addressed to a probing of axion-like particles [35,51,52] in LSthinW setup for both distant and encapsulated receiver. We leave that task for future work.…”

We address the radio frequency (RF) cavity experiment for probing dark photons which is a modification of the light-shining-through-thin-wall (LSthinW) setup with a relatively thin conducting barrier between cylindrical emitter and hollow receiver. The regarding experimental facility allows to probe dark photons effectively even in the off-shell regime, i. e. when dark photons mass exceeds the driven frequency of the emitter cavity, that is pumped by electromagnetic mode. We compare the sensitivity of two concrete setup configurations: two cylindrical cavities placed to each other by an end-caps, and nested geometry of the cavities in which the cylindrical receiver is encapsulated into the emitter. We show that for a certain range of dark photon mass the nested configuration can provide an enhanced sensitivity if one compares that with a separated emitter setup.

Near-threshold $$p\bar{\Lambda }$$ p Λ ¯ mass spectra for the reactions $$e^+e^- \rightarrow K^- p\bar{\Lambda }$$ e + e - → K - p Λ ¯ and $$J/\psi \rightarrow K^- p\bar{\Lambda }$$ J / ψ → K - p Λ ¯ are investigated with an emphasis on the role played by the interaction in the $$p\bar{\Lambda }$$ p Λ ¯ system. As guideline for the $$p\bar{\Lambda }$$ p Λ ¯ interaction a variety of $$\Lambda \bar{\Lambda }$$ Λ Λ ¯ potential models is considered that have been established in the analysis of data on $$p{\bar{p}}\rightarrow \Lambda \bar{\Lambda }$$ p p ¯ → Λ Λ ¯ in the past. Arguments why the properties of the $$p\bar{\Lambda }$$ p Λ ¯ and $$\Lambda \bar{\Lambda }$$ Λ Λ ¯ interactions can be expected to be very similar are provided. It is shown that the near-threshold enhancement in the invariant mass observed for the $$e^+e^-$$ e + e - reaction can be reproduced quantitatively by the assumed $$p\bar{\Lambda }$$ p Λ ¯ final-state interaction in the partial wave suggested by an amplitude analysis of the experiment. The effect of the $$p\bar{\Lambda }$$ p Λ ¯ final-state interaction in other decays is explored, including the recently measured reactions $$B^- \rightarrow J/\psi \, {\bar{p}} \Lambda $$ B - → J / ψ p ¯ Λ and $$B^+ \rightarrow J/\psi \, p \bar{\Lambda }$$ B + → J / ψ p Λ ¯ . It is found that the final-state interaction improves the description of the measured invariant mass near threshold in most cases.
