Finite size effects on measures of critical exponents in d=3 O(N) models Ballesteros, H. G. Fernández Pérez, Luis Antonio Martín Mayor, Víctor Muñoz Sudupe, Antonio 53 51-73 QCD phase-transitions Renormalizacion-group Heisenberg-model XY-model Dimensions.

We study the critical properties of three-dimensional O(N) models, for N = 2,3,4. Parameterizing the leading correctionsto-scaling for the r] exponent, we obtain a reliable infinite volume extrapolation, incompatible with previous Monte Carlo values, but in agreement with e-expansions. We also measure the critical exponent related with the tensorial magnetization as well as the v exponents and critical couplings.
