2 00 1 Temperature phase transition and an effective expansion parameter in the O ( N ) - model


The temperature phase transition in the N-component scalar field theory with spontaneous symmetry breaking is investigated in the pertur-bative approach. The second Legendre transform is used together with the consideration of the gap equations in the extrema of the free energy. Resummations are performed on the super daisy level and beyond. The phase… (More)
