Edinburgh: Hajrah, Robervaal, Victoria
Mark showed some plots that will form part of his talk in the general physics meeting tomorrow (see previous post). They show the y-cut that is required to ensure that all of the electron EM clusters are grouped together into a single jet. This is shown both for "undecayed" (i.e. no brehmsstrahlung within the tracking volume) and for all electrons. The y-cut value decreases with energy as expected, and is orders of magnitude smaller than values expected for hadron jets.
The final plot shows the distribution of electron track pT (green), total jet energy (orange) and single cluster energy (pink).
Hajrah has made an impressive start with Mokka/Marlin on muon ID. She is looking at the energy deposits and number of hits as muons traverse the calorimeters and will proceed to investigate the muon chambers.
The next meeting will be in two weeks, and they will remain fortnightly until further notice.
