Query: Extracting baryon-antibaryon strong interaction potentials from
  p$\bar{\Lambda}$ femtoscopic correlation function   The STAR experiment has measured $p\Lambda$, $\bar{p}\bar{\Lambda}$,
$\bar{p}\Lambda$, and $p\bar{\Lambda}$ femtoscopic correlation functions in
central Au+Au collisions at $\sqrt{s_{NN}}=200$ GeV. The system size extracted
for $p\Lambda$ and $\bar{p}\bar{\Lambda}$ is consistent with model expectations
and results for other pair types, while for $p\bar{\Lambda}$ and
$\bar{p}\Lambda$ it is not consistent with the other two and significantly
lower. In addition an attempt was made to extract the unknown parameters of the
strong interaction potential for this baryon-antibaryon ($B\bar{B}$) pair. In
this work we reanalyze the STAR data, taking into account residual femtoscopic
correlations from heavier $B\bar{B}$ pairs. We obtain new estimates for the
system size, consistent with the results for $p\Lambda$ and
$\bar{p}\bar{\Lambda}$ pairs and with model expectations. We give new estimates
for the strong interaction potential parameters for $p\bar{\Lambda}$ and show
that similar constraints can be given for parameters for other, heavier
$B\bar{B}$ pairs.
