Title: Asymptotic freedom of massless λΦ4 theories
Abstract: The crucial role of the mass renormalization condition leading to spontaneous symmetry breaking in λΦ4 theory is discussed. By using the renormalization group equations and a variational estimate of the ground state energy, it is suggested that massless λΦ4 theory in four dimensions is asymptotically free, not in contradiction with known rigorous results.
