INTERNATIONAL WORKSHOP ON RELATIVISTIC DYNAMICS AND FEW-HADRON SYSTEMS
The International Workshop on Relativistic Dynamics and Few-Hadron Sytems is devoted to a discussion of viable relativistic approaches in particle and nuclear physics. In the first week the emphasis is on particle physics, while in the second week nuclear problems are stressed. Insights gained in recent experimental activities related to the investigation of few-hadron systems, and in many-body relativistic approaches relevant for astrophysics and heavy-ion researches will also be discussed.

List of Topics
Scientific motivation
A lot of accurate measurements of properties of both nucleons and nuclei (e.g. electroweak properties) will be soon available, due to the experimental activity in laboratories in the USA, e.g. the Thomas Jefferson National Accelerator Facility (the former CEBAF), and in Europe, MAMI (Mainz) and ELSA (Bonn), in the kinematical region from about 1 to 6 GeV. This fact requires a relevant effort on the theoretical side in order to perform relativistic calculations of the measured quantities. However, as is well known, this task is very difficult, if one would want to fully solve the relevant relativistic field theory, due to the presence of an infinite number of degrees of freedom. Therefore, using approaches that belong to the domain between nonrelativistic quantum mechanics and fully relativistic field theory represents an interesting source of phenomenological knowledge, that in turn can yield useful hints for improving these approaches. Moreover, these models could quickly provide many calculations for a reliable analysis (i.e. including the major features of the strong interaction and satisfying relativistic invariance) of the forthcoming experimental data.
Aim of the workshop
The workshop aims at stimulating this kind of investigations, through a detailed discussion of theoretical frameworks adopted and numerical approximations used. Another aim is to analyse the feasibility of extending the field of applications of these approaches. Since a detailed comparison is fundamental, physicists actively involved in these relativistic calculations are invited, and sufficient time will be given for discussing the comparison of theoretical ideas and numerical results. Therefore the workshop has the format of a "working group meeting". In particular it focusses on relativistic predictions of low-energy and electroweak properties of hadrons, calculated within models obtained by truncating the full field theory (Bethe-Salpeter equation and related approximations for solving it, such as quasi-potential approaches) and within models based on hamiltonian approaches, where only a finite number of degrees of freedom is considered at the very beginning and relativistic invariance is kept as much as possible.
Support
The workshop has no registration fee. The ECT* will not cover travel expenses but will generously support up to 70% of Lit. 120,000/day (~61 euro) corresponding to the local expenses for accommodation in a double room + lunch and dinner. An extra amount of Lit. 40,000/day (~20 euro) should be paid for a single room accommodation. The workshop participants are asked to cover their part of the local expenses. The balance is to be paid to the ECT* upon arrival.
However, in order to make events like this one successful, we must appeal to the portion of the community which can cover its own expenses (this typically corresponds to the more senior and established researchers) since ECT* is not a profit-making organization, only the understanding of some generous participants that choose to totally or partially forsake ECT* support will enable us to cover the expenses of some of the more junior speakers as well as to possibly attend to some exceptional cases.
Finally please note that the ECT* kindly invites a donation of Lit. 50,000 (~25 euro) to contribute towards social activities of the Centre.
