Abstract
Cross-talk between the 
and 
sources of hadron production at
LEP2 offers a hope to learn about basic properties of QCD, but at the same
time threatens high-precision measurements of the 
boson mass. Directly
visible effects are not expected to be large, however. It is, therefore,
important to develop methods to measure the level of interconnection
in the data -- `connectometers'. In this article we study one particular
set of observables, namely the reduced rate of low-momentum particle
production caused by reconnection. In realistic scenarios the expected
signals are at the border of visibility, but not quite beyond reach. Special
studies on kaons and protons, or with other subsets of the data, could
provide supporting evidence. We also show how LEP1 
events could
be used to define an alternative reference sample.
