A poledipole relativistic string model
Abstract
A relativistic string model is proposed, whose mass spectrum is built up by a denumerable set of 3dimensional isotropic oscillators. This model has no covariance problem and its nonrelativistic limit describes a string with constant mass distribution and constant linear tension. However, this string has a poledipole structure, as shown by its energymomentum tensor, i.e., it has no extension.
