Dynamical NNLO parton distributions and the perturbative stability of F_L(x,Q^2)

M. Glück, C. Pisano, E. Reya

It is shown that the previously noted extreme perturbative NNLO/NLO instability of the longitudinal structure function F_L(x,Q^2) is a mere artefact of the commonly utilized `stand…

Decay b -> (c\bar{c}) s in the leading logarithm approximation

C. Bobeth, B. Grinstein, M. Savrov

We consider an effective field theory for the nonleptonic decay in which a heavy quark decays into a pair of a heavy quark and antiquark having a small relative velocity and one re…

Coherent Pion Production by Neutrinos

E. A. Paschos

I concentrate in this article on the reaction--coherent pion production by neutrinos incident on nuclei. A special effort is made in order to describe the approximations entering t…

Dynamical parton distributions of the nucleon and very small-x physics

M. Glück, P. Jimenez-Delgado, E. Reya

Utilizing recent DIS measurements (F_{2,L}) and data on dilepton and high-E_{T} jet production we determine the dynamical parton distributions of the nucleon generated radiatively…

Leptonic color models from Z_8 orbifolded AdS/CFT

K. S. Babu, Thomas W. Kephart, Heinrich Päs

We study orbifold compactifications of the type IIB superstring on AdS_5 x S^5/Gamma, where Gamma is the abelian group Z_8, which can lead to non-SUSY three and four family models…

Angular Distributions of B -> K ll Decays

Christoph Bobeth, Gudrun Hiller, Giorgi Piranishvili

We model-independently analyze the angular distributions of B -> K ll decays, l = e, mu, for low dilepton mass using QCD factorization. Besides the decay rate, we study the forward…

Charged-Higgs Collider Signals with or without Flavor

Stefan Dittmaier, Gudrun Hiller, Tilman Plehn +1

A charged Higgs boson is a clear signal for an extended Higgs sector, as for example predicted by supersymmetry. Squark mixing can significantly change the pattern of charged-Higgs…

Single pion electro-- and neutrinoproduction on heavy targets

E. A. Paschos, I. Schienbein, J. -Y. Yu

We present a calculation of single pion electroproduction cross sections on heavy targets in the kinematic region of the Delta(1232) resonance. Final state interactions of the pion…

The Lamb shift contribution of very light millicharged particles

M. Gluck, S. Rakshit, E. Reya

The leading order vacuum polarization contribution of very light millicharged fermions and scalar (spin-0) particles with charge εe and mass μto the Lamb shift of the hydrogen atom…

Photon polarization from helicity suppression in radiative decays of polarized Lambda_b to spin-3/2 baryons

G. Hiller, M. Knecht, F. Legger +1

We give a general parameterization of the Lambda_b --> Lambda(1520) gamma decay amplitude, applicable to any strange isosinglet spin-3/2 baryon, and calculate the branching fractio…
