Four-dimensional asymptotically free large N gauge theories compactified on S(R)(3)Ã—R have a weakly coupled confining regime when R is small compared to the strong scale. We compute the vacuum energyâ€¦ (More)

In the modern on-shell approach, the perturbative S matrix is constructed iteratively using on-shell building blocks with manifest unitarity. As only gauge invariant quantities enter in theâ€¦ (More)

Merging Einsteinâ€™s relativity with quantum mechanics leads almost inexorably to relativistic quantum field theory (QFT). Although relativity and non-relativistic quantum mechanics have been on solidâ€¦ (More)
