Shahzhad:
I produce the Ntuples from the HGTD Analysis for "Pi+" particles with mu(Pileup=0). These Ntuples contains the informations of Tracks(Pt, eta etc) and Hits(coordX, CoordY etc). The Ntuples will be used to obtain the informations about the "Hits" properties. I also discuss with Prof.Wang about how to calculate the number Hits per Event in the detector to know about the showing in HGDT. We will write our own Analysis code to calculate the number of Hits per Event which will also be a cross check for the one written by Alexander.
Adrian:
For VHbb analysis a new CxAOD production is under preparation with new derivations. I compared a production with the same recent code of the two days ago on both old derivation and new derivation, for the three channels (0L, 1L, 2L). The same number of events are observed, which is great. But an increase in CxAOD size is seen, which is not good, so this is under investigation. I presented the slides also in the Hbb meeting and triggered discussion about fixing this.
Rachid:
I reported on two new students that will work with me.
Song-Ming:
Preparing the heavy ion (HI) production for data quality. Next week Adrian to create reference plots for HI.
In HH->bbtautau, trained an MVA with the current code. No major improvement seen. There is software on a faster BDT, but that is to be discussed with collaborators that have this software. Also studied the addition of MET trigger and a small gain of 2-3% is observed. Though small, every little gain is important for this analysis.
There are minutes attached to this event.
