  1. 1.

    It should be noted that the calculation on which this figure is based uses a method which creates metastable flux tubes, which are then allowed to propagate for a relatively short Euclidean time interval. This procedure is insensitive to the string-breaking process, and hence one can only calculate the string tension of the metastable states.

  2. 2.

    To add to the “Casimir” confusion, the Lüscher term is known to string theorists as the “Casimir energy.”
