Searches for invisible Higgs decays in weak boson fusion are a well-known laboratory for jets and QCD studies. We present a series of results on tagging jets and central jet activity. First, precision analyses of the central jet activity require full control of single top production in some analyses. Second, the rate dependence on the size of the tagging jets is not limited to weak boson fusion. For the first time, we show how subjet information on the tagging jets and on the additional jet activity can be used to extract the Higgs signal. The additional observables relieve some of the pressure on other, critical observables. Finally, we compare the performance of weak boson fusion and associated Higgs production.

Strong di-jet correlations have been observed in p + p and d + Au collisions at [Formula: see text]. It is important to study how this jet-correlation is affected by the hot, dense medium produced in heavy-ion collisions at RHIC. In this contribution we will study the two particle correlation and probe how the di-jet shape evolves as a function of centrality in Cu + Cu collisions comparing to p + p , specifically using the near-side width and pT out . We will use high pT reconstructed π0 as our identified trigger in tagging jets.
