Goals for PUBLIC presentations S 02

• Pick 3 basic topologies
• W(ln)jets
• Z(ll)jets
• Z bb
• What will we have?
• Basic selections with event distributions
  overlaid with Monte Carlo
• Both tagged and untagged samples
• Event rate comparisons? Physics cross sections?

Subgroup Organization

• Plan to organize along physics final states
• Single lepton ET WH, ttH
• Multi-lepton ZH, WH(HWW)
• ET jets ZH, H tt
• Jets bbH (Green
  1st analyses)
• Some are naturally forming (e.g., jets) GOOD!
• Others we will start soon
• Students and post docs that sign up are
  responsible for getting the job done on a daily
  basis
• If you are busy now, think about waiting
• Conveners will act as obstacle removers and
  advisors

Subgroup Organization, cont

• Common basic selections are a clear goal
• same thresholds and h as much as is sensible
• Object ID
• start with object ID groups definitions
• are these right for us?
• Searches are different than precision
  measurement
• If not, must feed back into object ID groups
• No choice is perfect will be cross group issues
• conveners job includes insuring a coherent effort
• Potential cross group areas Triggers, mass
  reconstruction, and, of course, others

Topics People

• On D0, students sign up for thesis topics
• Confirmed by spokes/phys. coordinator
• Post docs are more free agents
• Based on initial HiT group list recent
  discussion
• Begun a table of people and topics
• Topic list will be extended/modified with time
• Talked with students advisors. Post docs
  somewhat guess work (today)
• With some concern for jumping the gun

There are clearly topics not here no one has
talked with us Also, some students have not yet
chosen a topic

Representation in other groups

• D0 Infrastructure groups
• TB, Suyong Choi
• ORB, Neeti Parashar
• Object ID MC
• We will need 51 representatives. Attendance at
  meetings not limited to these ?
• People working on a given channel should not wait
  around for IDs. Work on this as part of
  analysis! ?
