High twists and the NNLO QCD corrections in DIS

S. Alekhin

We discuss interplay between the high-twist (HT) terms in the operator-product expansion and the next-to-next-to-leading-order (NNLO) QCD corrections to the deep-inelastic-scatteri…

A stable hierarchy from Casimir forces and the holographic interpretation

Jaume Garriga, Alex Pomarol

We show that in the Randall-Sundrum model the Casimir energy of bulk gauge fields (or any of their supersymmetric relatives) has contributions that depend logarithmically on the ra…

Forward-backward and isospin asymmetry for B -> K* l+ l- decay in the standard model and in supersymmetry

Thorsten Feldmann, Joaquim Matias

We discuss two dedicated observables in exclusive B -> K* l+ l- decay that can be used to study effects of physics beyond the standard model, namely the forward-backward asymmetry…

Estimate of B(K -> pi nu nubar) from Standard Model fits to lambda_t

S. H. Kettell, L. G. Landsberg, H. Nguyen

We estimate B(K -> pi nu nubar) in the context of the Standard Model by fitting for lambda_t = Vtd x V*ts of the `kaon unitarity triangle' relation. We fit data from epsilon_K, the…

The possible test of the calculations of nuclear matrix elements of the -decay

S. M. Bilenky, J. A. Grifols

The existing calculations of the nuclear matrix elements of the neutrinoless double -decay differ by about a factor three. This uncertainty prevents quantitative interpretation…

The `s-rule' exclusion principle and vacuum interpolation in worldvolume dynamics

Joaquim Gomis, Paul K. Townsend, Mattias N. R. Wohlfarth

We show how the worldvolume realization of the Hanany-Witten effect for a supersymmetric D5-brane in a D3 background also provides a classical realization of the `s-rule' exclusion…
