Twist-2 at five loops: wrapping corrections without wrapping computations

Wrapping at four loops in N = 4 SYM

We present the planar four-loop anomalous dimension of the composite operator tr(φ [Z,φ]Z) in the flavour SU(2) sector of the N = 4 SYM theory. At this loop order wrapping interactions are present: they give rise to contributions proportional to ζ(5) increasing the level of transcendentality of the anomalous dimension. In a sequel of this paper all the details of our calculation will be reporte...

Four Loop Twist Two, Bfkl, Wrapping and Strings

The anomalous dimensions of twist two operators have to satisfy certain consistency requirements derived from BFKL. For N = 4 SYM it was shown that at four loops, the anomalous dimensions derived from the all-loop asymptotic Bethe ansatz do not pass this test. In this paper we obtain the remaining wrapping part of these anomalous dimensions from string theory and show that these contributions e...

Generic Wrapping

Component software means reuse and separate marketing of pre-manufactured binary components. This requires components from different vendors to be composed very late, possibly by end users at run time as in compound-document frameworks. To this aim, we propose generic wrappers, a new language construct for strongly typed class-based languages. With generic wrappers, objects can be aggregated at...
