Identifying massive hadronic decays in SUSY decay chains.

Line: 8 to 8
  We'll start by assuming that in a SUSY pair production, one decay chain has allowed us to remove all non-SUSY backgrounds, and what we are trying to do is interrogate/unpick the second decay chain to learn more about the SUSY spectrum. In particular we are looking at high ET jets and seeing they come from hadronic decays of W or Z.

John: I suggest that we use the benchmarks postulated in hep-ph/0508198, particularly scenarios \alpha, \beta, \gamma and \delta. The first three have neutralino dark matter but non-universal Higgs mases (NUHM), with parameters chosen to get varying branching ratios for \chi_2^0 \to Z,H \chi_1^0, as seen in Fig. 2. I do not know offhand about the \chi^\pm \to W \chi decays.

  The point \delta has gravitino dark matter, but the neutralino is the next-lightest sparticle and its decays are invisible. Hence, all four points have 'standard' missing energy signatures.
