Christina Markert 23 rd WWND Montana, Big Sky, Feb Conclusion and future plans Hadronic low momentum resonances are affected by hadronic interaction medium Measurement provides lifetime between chemical and thermal freeze out High momentum resonances from jets might be used as a tool to trigger on early produced resonances and test chiral symmetry restoration if they leave the hadronic medium without interaction Need theoretical description of resonance momentum and medium density when decay occur. Study p+p and Au+Au data with different p T selections for associated and trigger resonances in hadron-resonance correlations. Reconstruct resonances in jets with shorter lifetime as  (1020) but sufficient statistics (e.g. K*,  )

Christina Markert 23 rd WWND Montana, Big Sky, Feb EMCal in ALICE Without single jet reconstruction only statistical Analysis possible.  Jet reconstruction Calorimeter necessary Major advantages at the LHC: -Jet energy known, i.e. measure effect as function of fractional momentum -Enhanced statistics in relevant resonance pt-Range (3-10 GeV/c) -Trigger on quark and gluon jets separately
