Physics tasks
- development of methods to determine efficiency, energy scale and
resolution from data using "clean" signals like Z®mmg
and cc®gJ/y®gmm
for photons and Z®ee, J/y®ee
and U®ee
for electrons
 | develop trigger and selection criteria |
| understand possible biases |
| develop analysis infrastructure so it can be run
quickly after the data comes |
develop and optimize "vanilla" definitions for electron
and photon identification
| useful for most analyses (except highly specialized
ones) |
| develop standard software that calculates the ID
variables |
| characterize performance (efficiency and fake rate)
with/without trigger matching |
Technical tasks (Algorithms)
- develop algorithms for in situ measurement of
tracker material
| using low ET photon conversions |
| using high ET electrons from W/Z |
develop inter-calibration scheme for PbWO4
crystals in situ using p0
decays
| trigger and off-line selection |
| position and energy corrections for soft photons |
| matrix inversion and iterative algorithms development |
Technical tasks (Software)
- DST implementation in CMSSW
- translation of ORCA algorithms into CMSSW
- analysis of cosmic/beam tests data
