From the theta vs p plot for pbar from Lambda Lambdabar I showed earlier, it looks like above 20 degrees, the antiprotons are not disappering but rather have their momenta very poorly reconstructed. Thus, in the projection, the dip in efficiency is not visible.
I will also check what happens if the production vertex is displaced in the XY-direction.
