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
