On KLT and SYM-supergravity relations from 5-point 1-loop amplitudes
KLT SYM-supergravity relations 5-point 1-loop amplitudes
2010/12/23
We derive a new non-singular tree-level KLT relation for the $n=5$-point amplitudes, with manifest $2(n-2)!$ symmetry, using information from one-loop amplitudes and IR divergences, and speculate how...
On form factors in N=4 sym

2010/12/23
In this paper we study the form factors for the half-BPS operators $\mathcal{O}^{(n)}_I$ and the $\mathcal{N}=4$ stress tensor supermultiplet current $W^{AB}$ up to the second order of perturbation th...
Dimensionally reduced SYM$_4$ at large-$N$: an intriguing Coulomb approximation
Coulomb approximation High Energy Physics
2010/12/23
We consider the light-cone (LC) gauge and LC quantization of the dimensional reduction of super Yang Mills theory from four to two dimensions. After integrating out all unphysical degrees of freedom, ...
Quantum 't Hooft loops of SYM N=4 as instantons of YM_2 in dual groups SU(N) and SU(N)/Z_N

2010/12/22
A relation between circular 1/2 BPS 't Hooft operators in 4d N=4 SYM and instantonic solutions in 2d Yang-Mills theory (YM_2) has recently been conjectured. Localization indeed predicts that those 't ...
