Meeting Notes for 7 Apr 2010

Common

• The boot HD on data3 is failing; ANL MCS is looking to see if they can scrounge a replacement (we might need to buy a new one)
• Ubuntu 10.04b1 is looking pretty good so far.

CMS

• CMS document
• Mihael is rapid-prototyping new-OGRE-interface with minimum-level changes
  • For the studies we have considered, do we need all of the options? (see below)
• New timeline/deadline?
• OGRE development?
  • DanK working on safeguarding things in case of failure modes
  • Mass plots as function composition
  • Different requirements - CMS-proper vs. I2U2
  • Issues with source control
    • Big drops of code are hard to integrate
    • DanK has other requirements and probably does not want to be tied to I2U2
    • Move to a DVCS like git or hg? Branching and merging and rebasing are easy!
• UI - we only need display elements for the specific studies
  • At the 'beginner' level, bypass some of those pieces? Hand them some stuff? Make it foolproof (even for a better fool)
  • TomL wants more power for more sophisticated users
  • z→(all charged leptops), z→ee, z→μμ, z→ττ, z→ee OR z→μμ
    • Beginner mode - only one box?
    • Advanced mores - the boolean constructor
• Right now, the 'plot selection' phase also transforms/filters the data coming in from the data-selection page.

• Students/teachers need to know: conservation rules (mass), a bit on the standard model, a bit about accelerators

• We discussed adding fitting of the plot (Gaussian, Lorenzian, Breit-Wigner, depending on the quality of the data) and decided it was more than we wanted to do at this stage. We discussed using a polynomial background.

• Tom J. brought up the possibility of measuring the lifetime of the Z with the same data. Randy nixed this.

• In response to this discussion and future e-mail, Tom L. put up a new proposal at http://i2u2projects.michianastem.org/CMS+e-Lab+Z+mass+study+workspace

LIGO

• Workshop last Monday (5 Apr) for home-schooled students
• New-Bluestone appears to be working fairly well; adding more features to reach parity with legacy-Bluestone and make it more awesome.
  • Chart exporting needed (gCharts? local gnuplot? the whole world wonders)
  • Heavy testing under IE6-8, Chrome, Firefox, Safari ...

Cosmic

• TomJ is working on split.pl
• Blessing project management page
