Minutes of the NFS-meeting held on 8/3/94:
===========================================
 
In this meeting we had no reports about finalized activities, but
a discussion around the table, about what the different activities
are at the moment.
 
Bernd Pagels:
-------------
* Optimization of Q-prime cut to further reduce 3Pi0 background.
* Looking at possibility of 'repairing' wrong gamma-gamma pairs.
* Study of tails in lifetime resolution.
 
Olaf Behnke:
------------
* Fine tuning of calibration of shower angle reconstruction.
* Working towards a final version of the calibration and the vertex
  reconstruction to be implemented in the official software
  (error calculation in ANAPB, vertex reconstruction in VXNFIT).
 
Guido Polivka:
--------------
* Energy calculation (including error on E) is implemented in ANAPB.
* The full Energy calibration (including ,W0,sigma(W0),Omega...)
  has still to be made available for everybody ! We decided NOT to add
  this software to VXNFIT, but to create a NEW LIBRARY for such tools,
  that are not constraint fits.
 
Marcin Wolter:
--------------
* Provides a routine for redefining a neutral shower around a kaon
  to be put into ANAPB.
* Study of possible background in data with 1 converted photon, using MC.
* Production of Ks-->Pi0Pi0 MC well on the way (statistics available
  at Collaboration meeting more than doubled !).
 
Thomas Ruf:
-----------
* Analysis of possible K0-->gamma gamma signal in data with 1 converted
  photon, shows no signal for such K0 decays.
* All data with 1 converted photon up to P24 should be reprocessed
  (using new knowledge about possible background) which corresponds to
  a CPU need of approximately 2 days on 2 alphas.
 
Andreas Schopper:
-----------------
* Last missing NFS456 filter data of P24 arrived this morning.
  The P24 NFSPROD production is therefore expected to finish this week !
* Starting to look at influence of possible future trigger decisions
  to enhance K0-->Pi0Pi0 statistics at data taking level per real time.
  (Any person interested, specially in NN's used in trigger, is welcome)
 
Request from Pi+Pi- analysis group to run MC on 'ETH-cluster':
--------------------------------------------------------------
* Everybody agreed, that approx. 7 days of our alpha CPU time can be
  used for Pi+Pi- MC production, as long as this production runs
  parasitically to all other (production and analysis) activities
  (as always done for any MC production on this cluster !).
 
A.O.B.
------
* We should foresee to have 'final plots' for all results from
  NFS-analysis by beginning of May latest. These plots should contain
  the full statistics up to P24 ! They will be used for the 'summer
  conferences' and for a coming status report.
 
 
Next meeting:

* We agreed to have the next NFS-meeting on Wednesday 6/4/94 at 10.30 h *
* in the CPLEAR meeting room.                                           *
