Query: Q-balls in the Wick-Cutkosky model   In the present paper Q-ball solutions in the Wick--Cutkosky model are
examined in detail. A remarkable feature of the Wick--Cutkosky model is that it
admits analytical treatment for the most part of the analysis of Q-balls, which
allows one to use this simple model to demonstrate some peculiar properties of
Q-balls. In particular, a method for estimating the binding energy of a Q-ball
is proposed. This method is tested on the Wick--Cutkosky model taking into
account the well-known results obtained for this model earlier.
