Higgs Physics

Autumn 2011

Lecturer: Katri Huitu AFO C325  191 50677 
Assistant: Tuomas Honkavaara  HIP A325  191 50532 

Lectures: Wed 14-16  Aud A315  (1st lecture 7.9.)
Lecture on 29.9, but no lecture on 5.10, 12.10
Instead of a lecture on Oct 12, read the article arXiv:1108.1183 by Falkowski et al and write a summary (max a4 by latex) answering e.g. these questions. Return the summary on Oct 12 noon to the exercise box. The questions will be discussed in the exercise session on Oct 13. The summary will be counted as half of a question in the home exam in the end of the course.

Exercises: Thu 10-12  until 20.10 Exactum C220  then BK106
No exercises on 29.9, but exercises on 5.10.
Problem solutions should be returned by Wednesday noon to the box located in the A-wing of the 2nd floor.
Home examination: 16-22.12.2011
