# The semi-classical energy of closed Nambu-Goto strings

October 10, 2016

We compute semi-classical corrections to the energy of rotating closed Nambu-Goto strings. We find the Regge intercept $a = 1 + \frac{D-2}{24}$ for $D$ dimensional target space. Also the discrepancy with the standard approaches to string quantization is clarified.
