Abstract
Pair creation of strings in time-dependent backgrounds is studied from an effective field theory viewpoint, and some possible cosmological applications are discussed. Simple estimates suggest that excited strings may have played a significant role in preheating, if the string tension as measured in the four-dimensional Einstein frame falls a couple of orders of magnitude below the four-dimensional Planck scale.
