Present: Chris,Christian,Fabio,Markus Summary of strategy discussed: ------------------------------ * cuts for charged and neutral tracks - rediscuss cuts on energy in calorimeters - clear problem (as ever) in HCAL, expert advise needed - up to now: more than 20% difference data/MC -> cut - charged track minimal momentum cut was also discussed Chris will continue * secondary vertices (MAMMOTH,PXPHOT,V0) - handling in SKELANA not possible at the moment - cuts on incoming could lead to energy losses - improvement of incoming track dp possible using secondary information - we need a list of "good" vertices Christian will investigate * EMFNOISE - veto will be implemented * b-tag reextrapolation - done in skelana, put a flag, stop filling VECP twice * energy of electrons - use best energy estimate for "standard electron" - deassociate showers, if no electron and not a mip deposite Markus to have a look (+experts from HPC/EMF) * primary vertex constraint - improve dp of VD only, IDVFT using primary vertex constraint fits Markus to have a look * recovery of lost tracks - refits without OD/FCB - deassociate calorimeter showers - P > sqrt(s)/2 fixings * forward electrons - new package Fabio to contact Frederica It was agreed that the new code should be steered by a set of flags/switches. -- ------------------------------------------------------------------------------ Markus Elsing, DELPHI Tel. *41 22 767 3338 CERN EP-Division (Office:13-3-046) Fax. *41 22 782 3084 1211 Geneva 23, Switzerland pri. *33 4 50 208727 E-mail:
