Physics at LHC

I host the LHC-D Wiki for the LHC-D Workshop .

Our DNS problems should be solved now, but if the above link http://www.lhc-physics.info/lhc-d/ doesn't work, please try lhc-d/ instead

Publications

There is no need to put a complete list of my publications on the web, because you can get a rather comprehensive list from SLAC's SPIRES database . You can even look for published papers in refereed journals and unpublished preprints and published workshop contributions separately. NB: most of the entries have links to online versions of the papers.

Lectures

Daß ich erkenne, was die Welt / Im Innersten zusammenhält: Die Physik der Elementarteilchen

A one-hour lecture for high-school students and teachers (in German) from 2004. Part of the lecture series Physik am Samstag (Saturday Morning Physics) of the Würzburg physics department.

• Transparencies: PDF file

Physics of Electroweak Gauge Bosons with Electron-Positron Linear Colliders

This is an introductory one-hour lecture (in German) from 1999 aimed at non-particle physicists. It never was designed to be unbiased!

• Transparencies: uncompressed PostScript or gzip compressed PostScript

Electroweak Physics Reloaded

This is the second part of a lecture series on electroweak physics at a linear collider aimed at beginning graduate students in experimental particle physics. It was presented at the Linear Collider Physics School 2003, Ambleside, UK. The first part was presented by Stefan Dittmaier.

• Transparencies: PDF file

Feynman Diagrams For Pedestrians

This is a set of lectures with exercises (in German) aimed at graduate students in experimental particle physics, which has been presented annually since 1999 at Herbstschule für Hochenergiephysik Maria Laach.

The transparencies are identical to the set that was used at Maria Laach 2008.

• Complete set of transparencies (sans solutions to the problems) for printing (tree-hugger's version with three transparencies per page): uncompressed PostScript or gzip compressed PostScript

• Complete set of transparencies for projections (not printer-friendly): PDF file

The Renormalization Group For Pedestrians

This is a set of four lectures (in German) aimed at graduate students in theoretical and experimental particle physics, which has been presented for the first time at 29. Herbstschule für Hochenergiephysik, Maria Laach, September 1997.

The transparencies are identical to the set used at Maria Laach:

• Introduction (1/4): uncompressed PostScript or gzip compressed PostScript
• The Renormalization Group (2/4): uncompressed PostScript or gzip compressed PostScript
