A Proposal for the Vector State in Vacuum String Field Theory
Radoslav Rashkov, K Sankaran Viswanathan
A previous calculation on the tachyon state arising as fluctuations of a brane in vacuum string field theory is extended to include the vector state. We use the boundary confor…
A Note on the Tachyon State in Vacuum String Field Theory
R Rashkov, K S Viswanathan
We re-examine the recent proposal of Rastelli, Sen and Zwiebach on the tachyon fluctuation of the vacuum string field theory representing a D25 brane, originally considered by Hata…
Background Independent Open String Field Theory with Constant B field On the Annulus
R. Rashkov, K. S. Viswanathan, Y. Yang
We study Witten's background independent open-string field theory in the presence of a constant B-field at one loop level. The Green's function and the partition function with a co…
Stress-Energy Tensors for Higher Dimensional Gravity
A. DeBenedictis, K. S. Viswanathan
We calculate, in the context of higher dimensional gravity, the stress-energy tensor and Weyl anomaly associated with anti-de Sitter and anti-de Sitter black hole solutions. The bo…
Counterterms for the Dirichlet Prescription of the AdS/CFT Correspondence
W. Mueck, K. S. Viswanathan
We illustrate the Dirichlet prescription of the AdS/CFT correspondence using the example of a massive scalar field and argue that it is the only entirely consistent regularization…
Dynamical Self-mass for Massive Quarks
Zheng Huang, K. S. Viswanathan
We examine dynamical mass generation in QCD with large current mass quarks. A renormalization group analysis is performed to separate fermion self-mass into a dynamical and a kinem…
