The amplitude needed poles where the particles appear, on straight line trajectories, and there is a special mathematical function whose poles are evenly spaced on half the real line— the Gamma function— which was widely used in Regge theory. By manipulating combinations of Gamma functions, ...
The first several terms in the q-expansion of each of these functions are φNS(τ ; V ) = q−1/2 + χNS(V ) + 276q1/2 + 2048q + 11202q3/2 + ···φNS(τ ; V ) = q−1/2 − χNS(V ) + 276q1/2 − 2048q + 11202q3/2 + ···φR(τ ; V ) = χR+...
wsong2014@mail.tsinghua.edu.cn Abstract: In IIB string theory on AdS3 background with NS-NS fluxes, we show that Brown-Henneaux asymptotic Killing vectors can be derived by requiring both the worldsheet equations of motion and Virasoro constraints are preserved near the asymptotic boundary of ...
The masses of some of the fermionic modes in the bottom of each tower as functions of the R charge in the boundary conformal theory are also rational. Furthermore the modes in the bottom of the towers originating from q forms on T11 can be put in correspondence with the BRS cohomology ...
A crucial role is played by the mixing of the blowing-up modes M k with the T-moduli in the Khler metric, and by the presence of the M k in the gauge kinetic functions. Supersymmetry breaking in these models is dominated by the auxiliary fields of the T-moduli, and phenomenologically ...
the partition function, in section 4, in terms of the well-known modular functions. The fermionic contributions to the partition function after suitable GSO projections are found to match with the type-IIA and type-IIB results. Finally in section 5 we draw conclusions from our work. 2 The N...
In this space, there are D0-branes in spiral orbits and D1-branes with or without flux on them. In particular, we observe imaginary parts of partition functions, and interpret them as the rates of open string pair creation for D0-branes and emission of winding closed strings for D1-...
We compute N-point correlation functions of pure vertex operator states(DK states) for minimal models coupled to gravity. We obtain agreement with the matrix model results on analytically continuing in the numbers of cosmological constant operators and matter screening operators. We illustrate this for...
in [12] for the nine-dimensional type IIB string theory. 2.2. SL(2, Z) symmetric expressions by including (p, q) strings We start with the Virasoro amplitude, with δ 0 as given in eq. (2.6). By writing the ζ-functions as series, it takes the form δ 0 = 2 ∞ k=1 ∞ m=...
