Connor Graham's Analysis |
| |
Non-analysis work this week:
- Obtained new grid certificate and am in the process of converting it from .p12 to .pem for Dirac and updating my associated readme file
|
|
<

- Continuing to Question Giuseppe on the HTCondor batch system, mentioned in the analysis meeting last week
- Consolodating the large quantity of information given last week into some notes in my log book and possibly in this twiki page too, depending on content

- VO Northgrid membership has expired, need to sort this out
- Swapped my dosimeter as requested (for annual calibration and checks)

Shifts |
| | Currently working on:
Generating a Kμ2 normalisation sample to compare the ππ0 and μ+ν normalised branching ratio values, to determine if anything has been missed in the systematics. |
|
<
< |
- Step 1: Start generating a sample of Kμ2 data with PNN like cuts from one burst (current file) and organise some output histograms
- Write a new tree to group useful output
- Step 2: Test on 100 bursts with HTCondor (Giuseppe will send me the instructions ASAP)

- Step 1: Start generating a sample of Kμ2 data with PNN like cuts from one burst (current file) and organise some output histograms [in progress]
- Write a new tree to group useful output [done along with a new function in the code]
- Still to get started on PNN like cuts
- Step 2: Test on 100 bursts with HTCondor (Stoyan will send me the instructions readme and associated codes when required)
|
| |
-
- Refine cuts and output histograms etc...
- Step 3: Run on 1k bursts (average run) with HTCondor to try and get some good results
- e.g. the number of kaon decays for Kμ2
|

- Important: The acceptance of each decay has to be studied carefully as not all elements cancel, so everything has to be considered for how it could affect the acceptance with respect to the other decay (PNN or Kμ2)
Possible parallel MC work:
- Altering the Geant4 setup to change the hadronic interaction probability in GTK3 to 1
- Generating on the order of 100M events
- Comparing with data
- Aim: to make an estimation of this background for the PNN errors
|
| | Finished:
Generating a Pnn sample from the Kaon code given to me by Giuseppe. |
| |
- -j 60 uses more cores to run the build, also speeding it up
