One-loop electroweak effects on stop-chargino production at LHC

M. Beccaria, G. Macorini, E. Mirabella +3

The process of stop-chargino production at LHC has been calculated in the Minimal Supersymmetric Standard Model at the complete electroweak one-loop level, assuming a mSUGRA symmet…

Rare K and B Decays in a Warped Extra Dimension with Custodial Protection

Monika Blanke, Andrzej J. Buras, Bjoern Duling +2

We present a complete study of rare K and B meson decays in a warped extra dimensional model with a custodial protection of (both diagonal and non-diagonal) Z d_L^i \bar d_L^j coup…

Hadronic top-quark pair production in association with a hard jet at next-to-leading order QCD: Phenomenological studies for the Tevatron and the LHC

S. Dittmaier, P. Uwer, S. Weinzierl

We report on the calculation of the next-to-leading order QCD corrections to the production of top--antitop-quark pairs in association with a hard jet at the Tevatron and at the LH…

The Color Dipole Picture and the Ratio of the Longitudinal to the Transverse Photoabsorption Cross Section

Dieter Schildknecht

The transverse size of q q-bar fluctuations of a longitudinally polarized photon is reduced relative to the transerve size of q q-bar fluctuation of a transversely polarized photon…

Dark Matter Candidates - Axions, Neutralinos, Gravitinos, and Axinos

Frank Daniel Steffen

The existence of dark matter provides strong evidence for physics beyond the Standard Model. Extending the Standard Model with the Peccei-Quinn symmetry and/or supersymmetry, compe…

Probing nonstandard interactions with reactor neutrinos

J. Barranco, O. G. Miranda, T. I. Rashba

New limits on the weak mixing angle and on the electron neutrino effective charge radius in the low energy regime, below 100 MeV, are obtained from a combined fit of all electron-(…
