Gauge theory of the string geodesic field.
A relativistic string is usually represented by the Nambu-Goto action in terms of the extremal area of a 2-dimensional timelike submanifold of Minkowski space. Alternatively, a family of classical solutions of the string equation of motion can be globally described in terms of the associated geodesic field. In this paper we propose a new gauge theory for the geodesic field of closed and open st...
متن کاملString field theory in the temporal gauge.
We construct the string eld Hamiltonian for c = 1 6 m(m+1) string theory in the temporal gauge. In order to do so, we rst examine the Schwinger-Dyson equations of the matrix chain models and propose the continuum version of them. Results of boundary conformal eld theory are useful in making a connection between the discrete and continuum pictures. The W constraints are derived from the continuu...
متن کاملSingular gauge transformations in string field theory
We show that the existence of a tachyon vacuum puts tight restrictions on the form of solutions to the equations of motion of string field theory. In particular, we demonstrate that every solution can be written as a – formal – gauge transformation of the tachyon vacuum. In order for a solution to be non-trivial, this gauge transformation must be singular and we argue that this will happen when...
متن کاملSiegel Gauge in Vacuum String Field Theory
We study the star algebra of ghost sector in vacuum string field theory (VSFT). We show that the star product of two states in the Siegel gauge is BRST exact if we take the BRST charge to be the one found in [1], and the BRST exact states are nil factors in the star algebra. By introducing a new star product defined on the states in the Siegel gauge, the equation of motion of VSFT is characteri...
