Abstract
Within the framework of generalized Papapetrou method, we derive the effective
equations of motion for a string with two particles attached to its ends,
along with appropriate boundary conditions. The equations of motion are the
usual NambuGotolike equations, while boundary conditions turn out to be
equations of motion for the particles at the string ends. Various properties
of those equations are discussed, and a simple example is treated in detail,
exhibiting the properties of Neumann and Dirichlet boundary conditions and
giving a small correction term to the law of Regge trajectories due to the
nonzero particle mass.
Key words:
Pbranes; classical theory of gravity; Regge trajectories; string theory.
