On 1/2-BPS Wilson-’t Hooft loops

چکیده
We investigate the 1/2-BPS Wilson-’t Hooft loops in N = 4 Super-Yang-Mills theory. We use the bulk D-brane with both electric and magnetic charges to calculate the all genus contribution of the circular loops. The expectation value of Wilson-’t Hooft loops are in perfect agreement with the result through supersymmetric condition and duality transformation in the gauge theory.

’t Hooft Expansion of 1/2 BPS Wilson Loop
We revisit the 't Hooft expansion of 1/2 BPS circular Wilson loop in N = 4 SYM studied by Drukker and Gross in hep-th/0010274. We find an interesting recursion relation which relates different number of holes on the worldsheet. We also argue that we can turn on the string coupling by applying a certain integral transformation to the planar result. July 2006
متن کاملBPS Wilson Loops on S at Higher Loops
We consider supersymmetricWilson loops of the variety constructed by Drukker, Giombi, Ricci, and Trancanelli, whose spatial contours lie on a two-sphere. Working to second order in the ’t Hooft coupling in planar N = 4 Supersymmetric Yang-Mills Theory (SYM), we compute the vacuum expectation value of a wavy-latitude and of a loop composed of two longitudes. We evaluate the resulting integrals n...
متن کاملWilson-’t Hooft operators in four-dimensional gauge theories and S-duality
We study operators in four-dimensional gauge theories which are localized on a straight line, create electric and magnetic flux, and in the UV limit break the conformal invariance in the minimal possible way. We call them Wilson-’t Hooft operators, since in the purely electric case they reduce to the wellknown Wilson loops, while in general they may carry ’t Hooft magnetic flux. We show that to...
متن کاملMagnetic Strings as Part of Yang–mills Plasma
Magnetic strings are defined as infinitely thin surfaces which are closed in the vacuum and can be open on an external monopole trajectory (that is, defined by 't Hooft loop). We review briefly lattice data on the magnetic strings which refer mostly to SU(2) and SU(3) pure Yang-Mills theories and concentrate on implications of the strings for the Yang-Mills plasma. We argue that magnetic string...

We study S-duality in N = 4 super Yang-Mills with an arbitrary gauge group by determining the operator product expansion of the circular BPS Wilson and ’t Hooft loop operators. The coefficients in the expansion of an ’t Hooft loop operator for chiral primary operators and the stressenergy tensor are calculated in perturbation theory using the quantum path-integral definition of the ’t Hooft ope...
