Reminder on Calorimeter Issues
Problems we know about and you know about
2
1. Z ? ee resolution
Crate based corrections
Smain Kermiche

• current efforts
• improved nlc/gain calibration to be applied in
  reco (jean-roch, robert)
• understanding of phi intercalibration at cell
  level (lei wang, sarah eno)
• understanding of simulation dead materials,
  effect of phi-cracks
• verification of sampling fractions
• use of CPS-energies

3
2. J/Psi ? ee linearity
Smain Kermiche

• understanding of trigger biases (smain)
• same study for Y
• study of W electrons pT spectrum, E/p

4
3. phi dependences
JET response
EM response
Alexander Kupco
Smain Kermiche
study of phi-dependence in jes (alexander
kupco) calorimeter/tracker alignment
verifications with electrons (maksym titov) cell
level phi-intercalibration (lei,
sarah) ?alignment implementations in
reco/calorimeter geometry
5
4. jes
Jet response as a function of em-frac
plans from jes, but manpower? ?assumption that
Run II calorimeter is compensated has chances to
be wrong (shorter integration time
?Wigmans) ?nobody looked so far ?compensation in
simulation
6
5. extension of acceptance
variables used in the H-matrix for CC fiducial
volume

• jet identification in ICR region (pieter houbon)
• electron identification in ICR region (qichun
  xu)
• understanding of shower shapes in fiducial
  region!
• understanding of very forward region
