Motivation<br />
Why we look on supersymmetric loops <strong>in</strong> N = 2 theories?<br />
• What from N = 4 SYM can be pushed to N = 2?<br />
• How S-duality acts? Can we compute vevs of Wilson and ’t<br />
<strong>Hooft</strong> and test S-duality precisely?<br />
• The loop observables <strong>in</strong> N = 2 theories are novel - not<br />
computable from Seiberg-Witten theory - hence we’ll learn<br />
someth<strong>in</strong>g new about N = 2 dynamics if compute them<br />
