Puneet Batra, Z. Chacko
We show how the symmetry breaking pattern of the simplest little Higgs model, and that of the smallest moose model that incorporates an approximate custodial SU(2), can be realized…

Transitions Between de Sitter Minima
Puneet Batra, Matthew Kleban
We investigate the cosmological signatures of instantons mediating tunneling between de Sitter minima. For generic potentials the Coleman-de Luccia instanton does not necessarily e…
