Directly used in the Z’ search. Details: Full study in NNLO & NLO in QCD. PDF sets: MSTW2008, CTEQ12, NNPDF21 Cross section estimations: Fully Exclusive W and Z package, FEWZ [2], at 68% C.L. Results: 250 GeV ~ 3-4% relative uncertainty 3 TeV ~ 33% -//-

PDF4LHC recipe applied on NNLO estimations from MSTW2008, CTEQ12 and NNPDF21 PDF sets. NNLO/NLO cross sections for MSTW2008, CTEQ12 and NNPDF21 PDF versus the di- lepton invariant mass. NNLO calculations with different PDF sets introduces uncertainties which are not covered by the PDF4LHC recipe for NNLO uncertainties based on NLO extrapolations.

Geralis, G. Daskalakis Integrated within Hbb & HiggsEXO CMS groups. Details from V.Giakoumopoulou. Looking for the CP-odd pseudoscalar Higgs (A) via its decay into a Z boson and the lighter CP-even scalar Higgs (h) which might be the Higgs-like boson recently discovered. Main production mechanism for A: gg  A, pp  bbA. Largest Br(A  Zh) : low tan  & M z +M h  M A  2M top. First steps in the analysis & feasibility studies.

Quevillon: arXiv: v1 [hep-ph] 5 Apr 2013 Implication of Higgs discovery at M h = 126 GeV  SUSY scale in MSSM might be high M S >>M Z The unknown scale M S and some other leading SUSY parameters can be traded against the measured value of M h, leaving only M A & tanβ as free parameters in the Higgs sector. Phenomenological consequence of high MS values  reopen the low tanβ region, tanβ  3-5
