China v 3 6 February 1, 2008 4 7 0 9 9 Abstract / h In the full effective potential (EFP) approach, we find that spon- p- taneous symmetry breaking (SSB) can, with the convexity of the full p EFP, lead to the prediction of the IR confinement of Higgs particles, e h adding difficulty to the experimental identification of Higgs particles. : The short distance behaviors remain intact. The whole presentation is v i given in the understanding that any QFT becomes UV well defined in X a more complete underyling theory according to a recently proposed r a strategy.

Precision tests of standard model have been the main activities of the particle physicists [1]. However, there are still some issues remaining unclear in the standard model, the most impor- tant one is the electroweak symmetry breaking and the Higgs mechanism–an aspect that is still mysterious and less understood. Many variants and/or improvements with respect to this vital sector of standard model have been proposed and
