8.811  Particle Physics II

Dear students,

I carefully read your course evaluations which are available online. 2-3 out of 10 students expressed that they were unhappy with the class, 8 students did not give feedback. The three items I isolated are
1) video lectures do not work
2) the material is not diverse, i.e. to much of the discussion was LHC centric
3) you struggeled with the homework

Your feedback is important to me and I would like to invite you to discuss your concerns in more detail. Please give me a call on skype (markus.klute) or find me in my office at MIT Jan 31st at 3pm.

Thanks, Markus

Dear all,

Please take a few minutes for the Online Subject Evaluations .

So far the response rate in 31% which is too low.

Thanks, Markus

Dear all,

Wed. 12/07 no class - presentations re-scheduled for 12/14
Mon. 12/12 student presentations
Tues. 12/13 "LHC Higgs Jamboree" at noon as part of the LNS Lunch Seminar
Wed. 12/14 student presentations from 12/07
Fri. 12/16 final deadline for assignments at noon
Best, Markus

Dear all,

The final deadline for all assignments in 8.811 is Dec. 16th 12pm ET.

While we were generouse with the due dates for assignments during the semester, the final deadline is not negoatible. We will not accept assignments after this date.

Best, Markus

Dear all,
V2 of the assignment has been uploaded to stellar. While preparing solutions to the assignment we noticed that you need some extra information, namely the time dependence of the LHC lifetime. The figure and some text has been added. Questions are still the same.
Please contact me if you have further questions.
Best, Markus

Some clarification:

Eq. 1 states our goal, we want to achieve max. integrated luminosity. Left side simple integrated the time dependent instantenous lumi from the beginning to the end of the fill. The right side assumes constant lumi for some time and adds the rest of the lumi of the fill where lumi leveling is not longer possible.

Fig. 1 is data taking from a fill where lumi leveling is not used.
