2 00 1 Gauge Invariance and Tachyon Condensation in Cubic Superstring Field Theory
The gauge invariance of cubic open superstring field theory is considered in a framework of level truncation, and applications to the tachyon condensation problem are discussed. As it is known, in the bosonic case the Feynman-Siegel gauge is not universal within the level truncation method. We explore another gauge that is more suitable for calculation of the tachyon potential for fermionic str...
متن کاملNonlinear gauge invariance and WZW-like action for NS-NS superstring field theory
We complete the construction of a gauge-invariant action for NS-NS superstring field theory in the large Hilbert space begun in arXiv:1305.3893 by giving a closedform expression for the action and nonlinear gauge transformations. The action has the WZW-like form and vertices are given by a pure-gauge solution of NS heterotic string field theory in the small Hilbert space of right movers.
متن کاملLight-Cone Gauge Superstring Field Theory and Dimensional Regularization
We propose a dimensional regularization scheme in the light-cone gauge NSR superstring field theory to regularize the divergences caused by the colliding supercurrents inserted at the interaction points. We study the tree amplitudes and show that our scheme actually regularize the divergences. We examine the four-point amplitudes for the NS-NS closed strings and find that the results in the fir...
متن کاملLight-cone gauge superstring field theory in linear dilaton background
The Feynman amplitudes of light-cone gauge superstring field theory suffer from various divergences. In order to regularize them, we study the theory in linear dilaton background Φ = −iQX with the number of spacetime dimensions fixed. We show that the theory with the Feynman iε (ε > 0) and Q > 10 yields finite results. e-mail: [email protected]
متن کاملD-brane and Gauge Invariance in Closed String Field Theory
We construct a system of bosonic closed string field theory coupled to a Dbrane. The interaction between the D-brane and closed string field is introduced using the boundary state which is a function of constant field strength Fμν and the tilt θ μ of the D-brane. We find that the gauge invariance requirement on the system determines the (Fμν , θ i μ)-dependence of the normalization factor of th...
