One Loop Calculation of Cosmological Constant in a Scale Invariant
  Theory
  We compute the cosmological constant in a scale invariant scalar field
theory. The gravitational action is also suitably modified to respect scale
invariance. Due to scale invariance the theory does not admit a cosmological
constant term. The scale invariance is broken by a recently introduced
mechanism called cosmological symmetry breaking. This leads to a nonzero
cosmological constant. We compute the one loop corrections to the cosmological
constant and show that it is finite.
