      θ Dependence of the spectrum of SU(N) gauge theories 

      Del Debbio, L.; Manca, G. M.; Panagopoulos, Haralambos G.; Skouroupathis, A.; Vicari, E. (2006)
      We study the θ dependence of the spectrum of four-dimensional SU(N) gauge theories, where θ is the coefficient of the topological term in the Lagrangian, for N 3 and in the large-N limit. We compute the O(θ2) terms of the ...
