New Physics, precision electroweak data and an upper bound on higgs mass

In this paper we express the effect of new physics on gauge boson self energy corrections through non-renormalizable dimension six operators. Using the precision electroweak data we then determine a lower bound on the scale ${\l}$ associated with the underlying new physics. The lower bound on $\l$ is then used to derive an upper bound on $m_h$ through the triviality relation.
