The Jet Multiplicity as a Function of Thrust

We calculate the average multiplicity of jets in ee annihilation as a function of both the jet resolution parameter, ycut, and the thrust T . Our result resums to all orders the leading and next-to-leading logarithms in ycut and 1− T , and is exact up to second order in αS. This allows a comparison between the number of jets found using jet algorithms and the ability to distinguish different je...

The product of two N = 8 supersingletons yields an infinite tower of massless states of higher spin in four dimensional anti de Sitter space. All the states with spin s ≥ 1 correspond to generators of Vasiliev's super higher spin algebra shs E (8|4) which contains the D = 4, N = 8 anti de Sitter superalgebra OSp(8|4). Gauging the higher spin algebra and introducing a matter multiplet in a quasi...
