On open superstring partition function in inhomogeneous rolling tachyon background
We consider open superstring partition function Z on the disc in time-dependent tachyon background T = f(xi)e μx0 where the profile function f depends on spatial coordinates. We compute Z to second order in derivatives of f and compare the result with some previously suggested effective actions depending only on first derivatives of the tachyon field. We also compute the target-space stress-ene...
متن کاملOn Superstring Disk Amplitudes in a Rolling Tachyon Background
We study the tree level scattering or emission of n closed superstrings from a decaying non-BPS brane in Type II superstring theory. We attempt to calculate generic n-point superstring disk amplitudes in the rolling tachyon background. We show that these can be written as infinite power series of Toeplitz determinants, related to expectation values of a periodic function in Circular Unitary Ens...
متن کاملClosed Superstring Emission from Rolling Tachyon Backgrounds
We compute the lowest components of the Type II Ramond-Ramond boundary state for the tachyon profile T (X) = λe / √ 2 by direct path integral evaluation. The calculation is made possible by noting that the integrals involved in the requisite disk one-point functions reduce to integrals over the product group manifold U(n)× U(m). We further note that one-point functions of more general closed st...
متن کاملInhomogeneous Fragmentation of the Rolling Tachyon
Dirac-Born-Infeld type effective actions reproduce many aspects of string theory classical tachyon dynamics of unstable Dp-branes. The inhomogeneous tachyon field rolling from the top of its potential forms topological defects of lower codimensions. In between them, as we show, the tachyon energy density fragments into a p-dimensional web-like high density network evolving with time. We present...
متن کاملTachyon Condensation and Background Independent Superstring Field Theory
We study quantum corrections at the one loop level in open superstring tachyon condensation using the boundary string field theory (BSFT) method. We find that the tachyon field action has the same form as at the disc level, but with a renormalized effective coupling λ = g s e −T /4 (g s is the renormalized dimensionless closed string coupling, e /4 is the tachyonic field expectation value) and ...
