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…
