Dear colleagues,
a (quite late, apologies..) reminder: a Theory Center Meeting is scheduled for next friday, 18-2-2011. As usual, please register at
http://www.nikhef.nl/pub/theory/registration/index.php
Best wishes, Eric
Agenda:
* Time: 10.00 - 17.00 * Talk 11.00-12.00, H320 Nikhef colloquium: Petr Vogl (Caltech) "How difficult would it be to detect the Cosmic Neutrino Background?"
* Time: 15.00 - 16.00 Student meeting/discussion Rob Knegjens (Nikhef): "Effective Field Theories"
An effective field theory is an approximation of a more complete theory where the degrees of freedom not relevant to the energy scale of interest have been removed. The (famous) example I will look at is Four Fermi Theory, but there are of course many more (the Standard Model likely being one as well). The focus of my talk will be on the Operator Product Expansion for weak current-current interactions, which I plan to discuss in the context of a specific B meson decay. In particular, I will discuss the matching procedure and the summing of large logs using the renormalization group.
* Talk 16.15-16.30-17.00, H320 S. Mert Aybat (Nikhef) "TMD Factorization and Evolution for TMD Correlation Functions"
* 17.00 Borrel _______________________________________________ Theory-center mailing list Theory-center@nikhef.nl https://mailman.nikhef.nl/mailman/listinfo/theory-center
Hello,
For those of you interested in historical articles (if any): In October 1990 I made a most amazing trip to the Soviet Union, invited by colleagues of ITEP (Moscow). For many years I had the impression that it would be worth the effort to write an article about that trip. Last October I realized that 20 years had passed since. So, I decided that "now or never" and I wrote the article the last week of December. It took still a few months until I got all the comments and corrections from the Russian colleagues involved in the story. So, below you can see the title and abstract of this article.
By the way, a few days ago my birthday took place but it coincided with the 25th anniversary of the Chernobyl disaster, so the cake was cancel (it seems that I have some predestination ties with the Soviet Union).
Cheers, Beatriz

Title: The Last Workshop on Theoretical Physics in the Soviet Union Authors: Beatriz Gato-Rivera Comments: Latex, 14 pages Subjects: General Physics (physics.gen-ph); Popular Physics (physics.pop-ph)
Twenty years ago, in October 1990, I found myself attending a workshop on Theoretical Physics in Chernomorka (Ukraine) intended only for Soviet physicists. That trip to the USSR/CCCP as well as the preceding months at CERN were highly surrealistic with plenty of adventures, crucial events and anecdotes, the most amazing one involving Niels Bohr. A few months later the Soviet Union collapsed. In this article I make a personal account on the happenings of 1990, with emphasis on my incursions into the European communist world during, and also before, that year.
