Critical Exponents for the n -Vector Model in Three Dimensions from Field Theory

We present a new calculation of the critical exponents of the $n$-vector model through field-theoretical methods. The coefficients of the renormalization functions of the ${({\stackrel{\ensuremath{\rightarrow}}{\ensuremath{\phi}}}^{2})}^{2}$ theory are expanded in powers of the coupling constant. As... View More
