Casimir energy of the Nambu-Goto string with Gauss-Bonnet term and point-like masses at the ends

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/56175We calculate (using zeta function regularization) the Casimir energy of the rotating Nambu-Goto string with the Gauss-Bonnet term in the action and point-like masses at the ends. The resulting value turns out to be negative for all values of the parameters of the model.LaTeX, 8 pages, 2 EPS figures, accepted for publication in Acta Phys.Pol.
