The abstract, sentence by sentence

arXiv listing abstract v1. Results and the main claim are underlined; .

By explicit evaluation of certain disk S-matrix elements in the presence of background B-flux, we find coupling of two open string tachyons to gauge field, graviton, dilaton or Kalb-Ramond antisymmetric tensor on the world-volume of a single non-BPS D$p$-brane. We then propose an extension of the abelian Dirac-Born-Infeld action which naturally reproduces these couplings in field theory. This action includes non-linearly the dynamics of the tachyon field much like the other bosonic modes of the non-BPS D$p$-brane. On the general grounds of gauge and T-duality transformations and the symmetrized trace prescription, we then extend the abelian action to non-abelian cases.

Original abstract

By explicit evaluation of certain disk S-matrix elements in the presence of background B-flux, we find coupling of two open string tachyons to gauge field, graviton, dilaton or Kalb-Ramond antisymmetric tensor on the world-volume of a single non-BPS D$p$-brane.

This action includes non-linearly the dynamics of the tachyon field much like the other bosonic modes of the non-BPS D$p$-brane. On the general grounds of gauge and T-duality transformations and the symmetrized trace prescription, we then extend the abelian action to non-abelian cases.

  • The action of the D5-brane pair becomes: S=-T_5∫d^6 x ( 1/√(H)√(-det(η_μν+H D_μR^a D_νR^b α_a α_b+F_μν ))) where H = 1 + k l_s^2/X^m X_m where again it is understood that $H$ is an $N ×N$ matrix, and X^m X_m = (R_0α_0)^2 +2 R_0 R^iα_0 α_i + ( R_i α_i )^2 This action resembles that of two non-BPS D5-branes proposed in [ref] in the case of vanishing transverse scalar fields: S= - T_5 ∫d^6x ( V(T) √(-det (η_αβ + λD_μT D_νT + λF_μν))).
