Ghost Number Cohomologies and M-theory Quantum States
نویسنده
چکیده
We review and develop the formalism of ghost number cohomologies, outlined in our previous work, to classify the quantum states of M-theory.We apply this formalism to the matrix formulation of M-theory to obtain NSR superstring action from dimensionally reduced matrix model.The BPS condition of the matrix theory is related to the worldsheet reparametrizational invariance in superstring theory, underlining the connection between unbroken supersymmetries in M-theory and superstring gauge symmetries.

متن کاملS-Duality as an Open String Gauge Symmetry
We demonstrate and discuss the connection between S-duality and string-theoretic picture-changing gauge transformation in the “infinite momentum frame”. The picturechanging transformation at zero momentum leads to the presence of the topological 5-form charge in the type IIB superalgebra (dimensionally reduced SUSY algebra of M-theory) which is attributed to the M5-brane. The topological charge...
متن کامل4 v 1 1 6 Se p 20 03 GEF - TH - 9 - 2003 Physical States at the Tachyonic Vacuum of Open String Field Theory
We illustrate a method for computing the number of physical states of open string theory at the stable tachyonic vacuum in level trun-cation approximation. The method is based on the analysis of the gauge-fixed open string field theory quadratic action that includes Fadeev-Popov ghost string fields. Computations up to level 9 in the scalar sector are consistent with Sen's conjecture about the a...
متن کاملThe Ground Ring of N = 2 Minimal String Theory
We study the N = 2 string theory or the N = 4 topological string on the deformed CHS background. That is, we consider the N = 2 minimal model coupled to the N = 2 Liouville theory. This model describes holographically the topological sector of Little String Theory. We use degenerate vectors of the respective N = 2 Verma modules to find the set of BRST cohomologies at ghost number zero–the groun...
متن کاملBrane-like States in Superstring Theory and the Dynamics of non-Abelian Gauge Theories
We propose a string-theoretic ansatz describing the dynamics of SU(N) Yang-Mills theories in the limit of large N in D = 4. The construction uses in a crucial way branelike states, open-string non-perturbative states described by vertex operators of non-trivial ghost cohomologies. As we have discussed in previous papers, these physical vertex operators do not account for particle states in the ...
