Query: Renormalization group improvement of the effective potential in massive
  $\phi^4$ theory   Using the method of renormalization group, we improve the two-loop effective
potential of the massive $\phi^4$ theory to obtain the next-next-to-leading
logarithm correction in the $\bar{MS}$ scheme. Our result well reproduces the
next-next-to-leading logarithm parts of the ordinary loop expansion result
known up to the four-loop order.
