To provide an advanced school that covers the most important techniques to study QCD and confinement, ranging from electromagnetic duality, through Wilson's renormalisation group to lattice gauge theory.
This ASI will be the culmination of the final phase of the six month programme on Non-perturbative Aspects of Quantum Field Theory taking place at the Newton Institute (Cambridge, UK) which started in January 1997, organised by David Olive, Pierre van Baal and Peter West.
The mathematical framework for elementary particle theories consists of a quantum field theory described by a nonlinear generalisation of Maxwell's equations. The least understood part concerns the strong force responsible for the structure of sub-nuclear particles and is called Quantum Chromo Dynamics (QCD). The aim of the ASI is to assemble world experts in this field who can evaluate the impact of the latest developments, particularly those centred around electromagnetic duality, the main theme of the preceding programme. This concept involves the interchange of electric and magnetic fields. Its usefulness stems from the fact that it also interchanges weak coupling with strong coupling. Weak coupling means that reliable results can be obtained from the first few terms in a series expansion, whereas at strong coupling such a truncation does not make sense.
Recent developments have revealed the role of supersymmetry in making electromagnetic duality precise in a large class of theories. Roughly this is because supersymmetry facilitates cancellations between fermionic and bosonic fluctuations. The ASI will review the new knowledge and its relation to approaches in which supersymmetry is absent, in a way aimed at workers in QCD, at the level of an advanced graduate student or junior researcher. It will address the long standing question of understanding how quarks are confined within subnuclear particles. The intention will be to stimulate further activity and progress.
To be more specific, a good understanding of the running of the coupling constant, of the Wilson renormalisation group and of the particle spectroscopy will feature in a number of lectures, setting out the framework in which non-perturbative issues in QCD should be discussed. The renormalisation group will be discussed in the context of the lattice, momentum-cutoff and light-front approaches and will give the students working knowledge of the notion of effective actions and their flow under the renormalisation group. Introductory lectures on supersymmetry will prepare for the new ideas on electromagnetic duality. In the presence of supersymmetry, both instantons and monopoles will contribute in very special ways, revealing deep results relevant for the dynamics of the theory. This will be contrasted against what is known from the non-supersymmetric studies.
An important theme that will be developed in this context is the conjecture that monopoles condensate, such that QCD forms a dual superconductor. It will be discussed through the lectures how so-called abelian projection introduced ten years ago by 't Hooft might provide an explicit scenario to test this dual superconductor picture. The recent Seiberg-Witten duality results add a new dimension to this conjecture, whose consequence for QCD will be discussed as much as possible. Another line of attack, that might in interesting ways be related to the dual superconductor pictures, has been the attempts to rewrite QCD as a string theory. Also here supersymmetry recently has been shown to be a useful technical tool.
We are planning to roughly allocate equal time to four main themes, developed in parallel as illustrated in the enclosed tentative schedule, namely (i) duality in the light of its possible application to QCD, (ii) general non-perturbative techniques aimed at understanding confinement, (iii) the role of instantons and monopoles played in confinement, including tests of the dual superconductor picture and finally (iv) lattice Monte Carlo results aimed at first principle calculation of the consequences of QCD, like the glueball and hadron spectrum and the influence of the strong force on CP violation and electro-weak processes.
This ASI is unique in bringing so many different approaches together, each expected to carry part of the solution towards the confinement problem. Any student that wishes to make progress on the confinement problem should be aware of these approaches and the ASI will in particular stimulate exploring the ideas of electromagnetic duality to further our understanding of confinement in QCD.
This school aims at advanced graduate students and junior postdoctoral fellows and researchers.

END OF ASI Friday July 4th, 5:00 pm.
The summer school will take place in the Mill Lane lecture rooms and accommodation for participants will be provided at nearby Selwyn College. Breakfast and evening meals are included for those that stay at Selwyn College. Lunch and refreshments during the days that lectures take place are provided for all registered participants (reception and conference dinner are included). The fee is £ 650 - please follow the instructions for payment provided in the e-mail sent around April 12, which also specifies the deadline of payment and the precise amount in case of partial subsidy. Information how to reach the Newton Institute can be found here, whereas Selwyn College is located on the corner of Grange Road and Sidgwick Avenue (continues as Silver Street towards the city centre, to which Mill Lane is parallel).
Attendance of lectures by local students and researchers is encouraged. For those that wish to take part in the lunches and use the refreshments, a nominal fee of £ 120 is charged. In the latter case registration before 31 May is required.

A total of 16(8) participants to the school have expressed interest in giving a short 10 minutes presentation (poster) on their work. We are pleased, but overwhelmed, by so much interest in this. As the NATO ASI is primarily intended as a school, we should not reserve too much time for talks by participants, in particular as the schedule with planned lectures is already relatively full. Therefore we propose that those who have indicated to want to give a talk, present a poster instead. Any way we feel this will do more justice to the work presented than a talk of 10 minutes.
We allocate one of the sessions from 5-6 pm (which may run till 7 pm) in each of the two weeks for poster presentations. We ask the authors to be available for answering questions during the appropriate session. Posters can be displayed for the whole week to stimulate further discussions on the basis of the work presented. In alphabetical order half the posters can be displayed during the first week (from Tuesday morning till Saturday) and the remaining half during the second week (from Monday morning till Friday morning).
Each poster is assigned 3 x 4 feet (0.9 x 1.2 meters). No pages can be allocated in the proceedings for the posters. Three people have withdrawn their poster during the school.
