Collaborative Research Center SFB 676

Particles, Strings, and the Early Universe



The Collaborative Research Center 676 (Sonderforschungsbereich 676) at Hamburg University is a research programme at the interface of Particle Physics, String Theory and Cosmology. Significant developments are taking place in each of these fields, and far-reaching scientific results are expected in the course of the next 20 years.

In order to benefit from the fruitful interplay between these different fields, the SFB includes researchers from many different backgrounds, reaching from Particle Physics, over to numerical modeling in Astrophysics, to Mathematics. Eliminating the traditional borders between these subjects has proven to be inspirational and has led to interesting interdisciplinary research projects.



Upcoming events
  • SFB Lecture: Building Supersymmetric Models for the LHC
    F. Brümmer
    15, 22 and 29 Jun 2012

    Low-energy supersymmetry is one of the best-motivated new physics scenarios for the LHC. In these lectures I will describe some tools for building potentially realistic SUSY models which allow to calculate soft SUSY breaking terms from first principles. After starting quite generally, the focus will eventually be on dynamical SUSY breaking and modern approaches to gauge mediation.

Past events
  • SFB Lecture: Two-dimensional conformal field theory: introduction & applications
    I. Runkel
    27 April, 05 and 11 May 2012

    In this series of three lectures I will give a brief introduction to conformal field theory in two dimensions, including some applications and the methods used to get there. Conformal field theories arise for example in the description of critical lattice models or as UV/IR renormalisation group fixed points. In two dimensions they feature an infinite symmetry algebra, the Virasoro algebra. From its representation theory one can extract a lot of information about the theory, such as differential equations for correlators and constraints on the field content and the short distance expansion of fields. I will illustrate this in some simple examples.

  • Implications of the Early LHC for Cosmology

    18-20 Apr 2012

    The aim of this workshop is to discuss the consequences of the early results obtained from LHC measurements for cosmology. The main topics covered are
    • The Higgs Sector
    • Status of Supersymmetry
    • Inflation
    • Cosmological Phase Transitions
    • Primordial Gravitational Waves

    DESY Hamburg, 2a/SemRm 2

  • XXIV Workshop Beyond the Standard Model

    12-15 Mar 2012

  • Amplitudes 2012

    5-9 Mar 2012

    During the last few years the analytic study of scattering amplitudes has flourished due to a vivid interaction between high energy physics, mathematics and string theory. The purpose of the workshop is to bring together leading experts working on novel methods for scattering amplitudes in perturbative gauge and gravity theories, reaching from formal developments to phenomenological applications. We intend to review progress and discuss promising developments in this highly energetic field. Thereby, we hope to inspire further development.
