Welcome!

We study the strong interaction at low and medium energies. Our activities focus on the theoretical interpretation of the experiments at MAMI and at other accelerator facilities. Beside analytical methods like effective field theories and dispersion theory numerical simulations of Quantum Chromodynamics on the lattice are applied.

SFB 1044 Worskhop

The Institute of Nuclear Physics and the Collaborate Research Center 1044 (SFB 1044) will host this 3-day workshop, which is devoted to electromagnetic processes and their role in advancing the understanding of low-energy nuclear physics and related areas. The workshop aims at identifying relevant electromagnetic observables, which should be measured with the upcoming MESA and the MAGIX facilities.For more information on the program and to register for the workshop, please go to the workshop website.

PRISMA+ Cluster of Excellence approved

Johannes Gutenberg University Mainz (JGU) has scored a great success in Germany's Excellence Strategy program: The Excellence Commission, consisting of 39 members of the international Committee of Experts appointed by the Joint Science Conference (GWK) and the research ministers of the German federal and state governments, has approved the PRISMA+ Cluster of Excellence. The total funding is expected to amount to EUR 64 million over the next seven years. PRISMA+ is the follow-up application of the Cluster of Excellence "Precision Physics, Fundamental Interactions and Structure of Matter" (PRISMA), which was successful in the previous Excellence Initiative and has received funding since 2012. ...

MITP workshop "Scattering Amplitudes and Resonance Properties from Lattice QCD"

In recent years, Lattice QCD (LQCD) calculations of stable-hadron properties have become considerably more precise, and as a result, LQCD inputs are having an increasing impact on Standard-Model phenomenology. Considering this progress, it is natural to also examine the prospects for using lattice QCD to calculate the properties of unstable hadrons, i.e. QCD resonances that decay via the strong force. The extraction of resonance properties is much more challenging, but also in this sector enormous progress has been made in the development of both theoretical methods and numerical techniques. The aim of this workshop is to bring together experts in developing the formalism and lattice practitioners, in order to review the status of ongoing calculations and discuss future prospects. The workshop will emphasize the future role of LQCD in precision resonance physics, especially in the context of forthcoming experiments. ...

New book by V. Pascalutsa

Theory group member Vladminir Pascalutsa has published a new book on sum rules and dispersion relations. Scattering of light by light is a fundamental process arising at the quantum level through vacuum fluctuations. This short book will explain how, remarkably enough, this quantum process can entirely be described in terms of classical quantities. This description is derived from general principles, such as causality, unitarity, Lorentz, and gauge symmetries. The reader will be introduced to a rigorous formulation of these fundamental concepts, as well as their physical interpretation and applications. ...
