Dirac quantization of nambu-goto open string theory in four-dimensional minkowski spacetime
Abstract
In this study, an approach is presented for eliminating anomalies in the quantum theory of Nambu-Goto relativistic open strings formulated in Minkowski spacetime of dimension d = 4. A key idea is to choose a light-cone gauge with the gauge axis related to the world sheet in a Lorentz-invariant way. In this approach, the Lorentz group transforms the world sheet along with the gauge axis and is not accompanied by reparametrizations. As a result, the theory becomes anomaly-free in the Lorentz group and in the group of intrinsic symmetries of the system. It is shown that the Abelian-type gauge conditions lead to an algebraically simple Hamiltonian mechanics, which is convenient for canonical quantization. The constructed quantum theory has a spinmass spectrum with Regge behavior.
