We report on a search for Standard Model (SM) production of Higgs to WW* in the two charged lepton (e, mu) and two neutrino final state in pp¯ collisions at a center of mass energy s = 1.96 TeV. The data were collected with the CDF II detector at the Fermilab Tevatron and correspond to an integrated luminosity of 1.9fb -1. The Matrix Element method is developed to calculate the event probability and to construct a likelihood ratio discriminator. There are 522 candidates observed with an expectation of 513+/-41 background events and 7.8+/-0.6 signal events for Higgs mass 160GeV/c 2 at next-to-next-to-leading logarithmic level calculation. The observed 95% C.L. upper limit is 0.8 pb which is 2.0 times the SM prediction while the median expected limit is 3.1+1.3-0.9 with systematics included. Results for 9 other Higgs mass hypotheses ranging from 110GeV/c2 to 200GeV/ c2 are also presented.

520 $a The same dilepton plus large transverse energy imbalance (/ ET ) final state is used in the SM ZZ production search and the WW production study. The observed significance of ZZ → llnunu channel is 1.2sigma. It adds extra significance to the ZZ → 4l channel and leads to a strong evidence of ZZ production with 4.4 sigma significance. The potential improvement of the anomalous triple gauge coupling measurement by using the Matrix Element method in WW production is also studied.
