Things to Know Next Year

-Even though almost everyone speaks english, try to speak to people in french! Even if it’s little things like “excusez-moi”, “parlez-vous anglais?”, “pardon”, “je voudrais…”, or “désolé”. It’s rude to just assume that people speak english.
-At the University of Geneva grades are on a scale of 0-6. You receive a zero if you don’t show up to the test. To pass you need a 4 or greater.
-Grades will be posted on your professors’ doors at the end of the semester; therefore, everyone will be able to see how you did. So try to work hard so you can at least save yourself from some embarrassment.
-For Quantum Mechanics read the Jean-Louis Basdevant and Jean Dalibard book because the final will be structured around that book, but definitely use Griffiths to better understand the material. The Basdevant and Dalibard book is pretty hard to read because it’s a translation from a french book, so it’s nice to read Griffiths on the side.
-For E&M you should definitely bring your freshman level book along with Griffiths. A lot of the material covered will be similar to that of your freshman course.
-Ask the swiss students if you can be added to their google group because they post a lot of useful information.
-If you’re staying for the summer make sure you get a bike before the summer students arrive because the bikes will go quickly.
-Free food and CMS EVO discussion every Fri at 17:30, Bat. 40
-If you work at CERN during the summer, you can try to get housing at Foyer Résidence Robert Schumann or EasyLoft (both are in St. Genis). They’re relatively cheap. There is also the CERN hostel, but that costs ~58 chf per night. You can try for free CMS housing, but you have to look into that well in advance and most likely there won’t be any available spots. If you live in Ferney Voltaire you can get to CERN by taking the Y bus from Ferney-Mairie.

sh v. csh

when we use the command: eval `scram runtime -~~~’ how do we know whether to use eval `scram runtime -sh` or eval `scram runtime -csh`? I understand they are different shells, but what difference will it make?


another site

This site explains some of the commands that Arno had us type into our terminal to get and run TriggerTest. I’m assuming that some of the commands they give you to set up the cms environment (for example: source /afs/ can all be done with the command: cmsenv.

Useful websites

This post is mostly directed to Michael and Elim but here are some useful links I’ve found:

For understanding python syntax:
For CMSSW cross-reference:

Let me know if you find any other good sites,

Hard Muons

Hi Edgar,
I was working on trying to figure out which muons are the hardest muons. Are the hardest muons the ones with the most energy? I scanned “mu_e”, but I can’t tell which muons have the highest energy because it seems scattered throughout the events.. I’m not sure if what I said makes sense.. I also thought that if I drew “mu_e” it would help me figure out which muons had the highest energy, but it plots the number of muons that had a particular energy, not which muon had what energy..right?
I’m aware that there is a GetMaximum function in TTree, but it won’t tell us which event produced the maximum will that help us?

Thank you,
