Example DV event displays

• Several SUSY models could give rise to displaced vertices:– Split SUSY / long-lived R-hadrons – Andy has generated

some samples– RPV SUSY with weak RPV couplings – we looked at this so

far with lambda^prime_211 coupling, and long-lived neutralino decaying to muon plus jets.• For 2012 paper, also looking at electron plus jets, and, and

neutralino (MET) plus jets, as well as lambda-double-prime coupling (just jets), and other physics models (GMSB – displaced Z and displaced Higgs, and decaying R-hadrons).

– Some examples here from the RPV muon+jets channel we used for 2012 CONF note (mode 114006).

Some naïve Atlantis questions:• How easy would it be to add a custom list of

reco vertices?• Would it then be possible to truncate tracks

from that vertex at the vertex position, rather than having ‘tails’ inside the vertex position?

Other thing I meant to do for this meeting but ran out of time:

• Find some ‘typical’ background events, e.g. Ks vertices, material interactions, for comparison.
