Abstract
Following recent work by Lambiase and Nesterenko we study in detail the
interquark potential for a Nambu-Goto string with point masses attached
to its ends. We obtain accurate solutions to the gap equations for the
Lagrange multipliers and metric components and determine the potential
without simplifying assumptions. We also discuss the Lüscher term
and argue that it remains universal.
