摘要：

A twisted scalar field conformally coupled to gravitation is used to calculate the vacuum stress-energy tensor in the background spacetime generated by an infinite straight gauge cosmic string. The result found has an absolute numerical value close to the one obtained with a nontwisted conformal scalar field, but their signs are opposite. © 1990 The American Physical Society.
