Stringy Corrections to Wilson Loop in N = 4 SYM Theory
Debashis Ghoshal
U. Munich
In the framework of the conjectured duality between
type IIB string on adS_5 x S^5 and N=4 supersymmetric Yang-Mills
theory, the expectation value of Wilson loop operators in the
latter is evaluated by calculating the string action. To lowest
order this is the minimal area of the string worldsheet whose
boundary is fixed to be at the given loop. We discuss sigma
model correction at one loop to this classical contribution.
The almuerzo-seminario is
intended to be an informal seminar and an open forum for discussion.
You are wellcome to bring your own
bocata (sandwich), or coffee or tea.
Where: Modulo C-XVI, 3rd floor,
Facultad de Ciencias U.A.M., C.U. Cantoblanco, 28049-Madrid
