Scientific paper

We found wormhole solutions, which connect a baby universe and a parent de Sitter (or a flat) universe through a tube with oscillating radius, in a theory which includes a term βR2. The size of this wormhole is bounded from above by √β/κ. including the effect of this wormhole, the problem of the cosmological constant is discussed also.
