Integral über alle Eichtransformationen (Diffeomorphismen undWeyl-Transformationen). h[γ] Die durch die Eichtransformation γ aus h erzeugte World-Sheet-Metrik. ĥ(t) Der aus dem durch die Moduli t bestimmten Eichorbit ausgewählte Repräsentant (ebenfalls eine World-Sheet-Metrik). ∏ (α,i)∈f . . . Produkt über eine Anzahl von Koordinaten auf dem World-Sheet, die der Anzahl der konformen Killing-Vektoren entspricht (α numeriert die zwei Dimensionen des WorldSheets, i numeriert Punkte auf dem World-Sheet).

DF-strings from D3D̄3 as Cosmic Strings
We study Dirac-Born-Infeld type effective field theory of a complex tachyon and U(1)×U(1) gauge fields describing a D3D̄3 system. Classical solutions of straight global and local DFstrings with quantized vorticity are found and are classified into two types by the asymptotic behavior of the tachyon amplitude. For sufficiently large radial distances, one has linearlygrowing tachyon amplitude and ...
متن کاملPerturbation theory in two-dimensional open string field theory.
In this paper we develop the covariant string field theory approach to open 2d strings. Upon constructing the vertices, we apply the formalism to calculate the lowest order contributions to the 4-and 5-point tachyon–tachyon tree amplitudes. Our results are shown to match the 'bulk' amplitude calculations of Bershadsky and Kutasov. In the present approach the pole structure of the amplitudes bec...
متن کاملAdelic Formulas for Gamma and Beta Functions of One-Class Quadratic Fields: Applications to 4-Particle Scattering String Amplitudes
Regularized adelic formulas for gamma and beta functions for arbitrary quasicharacters (either ramified or not) and in an arbitrary field of algebraic numbers are concretized as applied to one-class quadratic fields (and to the field of rational numbers). Applications to 4-tachyon tree string amplitudes, to the Veneziano (open strings) and Virasoro (closed strings) amplitudes as well as to mass...
متن کاملW 3 string scattering
The group theoretic method is extended to include fields with a background charge. This formalism is used to compute the tree level scattering for W 3 strings. The scattering amplitudes involve Ising model correlation functions. A detailed study of the four tachyon amplitude shows that the W 3 string must possess additional states in its spectrum associated with intercept 1/2 and the energy ope...
متن کاملClosed Strings in Misner Space: Stringy Fuzziness with a Twist
Misner space, also known as the Lorentzian orbifold R1,1/boost, is the simplest tree-level solution of string theory with a cosmological singularity. We compute tree-level scattering amplitudes involving twisted states, using operator and current algebra techniques. We find that, due to zero-point quantum fluctuations of the excited modes, twisted strings with a large winding number w are fuzzy...
