Absence of resonant decay for metastable vacua in gauge theories of scalar fields
M. Cardella, S. Elitzur, E. Rabinovici
We prove the impossibility of resonant decay of a metastable vacuum in a theory of a scalar field coupled to a gauge field. Our result extends to gauge theories of scalar fields a…

Multitrace Deformations of Vector and Adjoint Theories and their Holographic Duals
S. Elitzur, A. Giveon, M. Porrati +1
We present general methods to study the effect of multitrace deformations in conformal theories admitting holographic duals in Anti de Sitter space. In particular, we analyse the c…

Removing Singularities
Shmuel Elitzur, Amit Giveon, Eliezer Rabinovici
Big bang/crunch curvature singularities in exact CFT string backgrounds can be removed by turning on gauge fields. This is described within a family of {SL(2)xSU(2)xU(1)_x}/{U(1)xU…
