Anomalous dimension in 2d non-linear sigma models
  OKC/Nordita High-Energy Physics Theory seminar

Speaker : Alessandra Cagnazzo (Nordita)
Abstract : 2d non-linear sigma models are widely used in high and low energy physics. In my talk I will present how to compute the one-loop anomalous dimension for fields in some cases in which the background is a coset space. I will review the formula for the case in which the background is a symmetric coset (that admit a $Z_2$ automorphism) and present the new result for $Z_4$-cosets. The last result is applicable to the string described by the hybrid model formalism on $AdS_5\times S^5$ and it is relevant for AdS/CFT.
