Parton shower/ME matching

Ongoing Projects:

• PS/ME matching in Ariadne (Leif Lönnblad)
• NLO+PS for HERA using a phase-space slicing technique (Thomas Schörner-Sadenius) HELP WANTED
• PS/ME matching in Pythia and Herwig (Stephen Mrenna)

Other proposed subtopics:

• W and multijet production at LHC
  (which models are available? do they work well at the tevatron?)
• ME+PS at HERA/DIS as a testbed
  (2+1 jet available, can we go higher? Heavy quarks?)
• NLL vs PS generated Sudakovs
  (Do we fully understand the differences?)
• ME generators
  (Do we have what we need? Are the interfaces working?)
• Tree-level vs NLO ME+PS
  (Pros and cons, which should be used for what? do we need NLO PS?)
• ME+PS for kT-factorization
  (Anyone working on this?)
• More or less complicated methods
  (Do we need the full CKKW, MC@NLO or Collins procedures, or can we simplify things?)
