Abstract

We are studying quantum corrections in the earlier proposed string theory based on worldsheet action which measures the linear sizes of the surfaces. At classical level the string tension is equal to zero and as it was demonstrated in the previous studies one loop correction to the classical worldsheet action generates Nambu–Goto area term, that is nonzero string tension. We extend this analysis computing the worldsheet effective action in the second order of the loop expansion. We are studying quantum corrections in the earlier proposed string theory based on worldsheet action which measures the perimeter of the surface. At the classical level the string tension is equal to zero and we demonstrate that one and two-loop corrections to the classical worldsheet action generates Nambu–Goto area term, that is nonzero string tension.
