Long-lived neutralinos as probes of gravitino dark matter

Jan Hajer
Supersymmetric extensions of the Standard Model with small R-parity and lepton-number violating couplings are naturally consistent with primordial nucleosynthesis, thermal leptogenesis and gravitino dark matter. We consider both supergravity models with universal boundary conditions at the grand unification scale and a scalar tau or bino-like neutralino as the next-to-lightest supersymmetric particle (NLSP) as well as hybrid gauge-gravity mediation models with a higgsino-like neutralino as the NLSP. Fermi-LAT data on the isotropic diffuse gamma-ray flux yield...

Determination of Delta G / G from open charm events at COMPASS

S. Koblitz
One of the main goals of the COMPASS experiment at CERN is the determination of the gluon polarisation in the nucleon, Delta G/G. It is determined from spin asymmetries in the scattering of 160 GeV/c polarised muons on a polarised LiD target. The gluon polarisation is accessed by the selection of photon-gluon fusion (PGF) events. A very clean selection of PGF events can be obtained with charmed mesons in the final state. Their detection is...

Novel master formula for twist-3 soft-gluon-pole mechanism to single transverse-spin asymmetry

Yuji Koike & Kazuhiro Tanaka
We prove that twist-3 soft-gluon-pole (SGP) cross section for single spin asymmetries is determined by a certain ``primordial'' twist-2 cross section up to kinematic and color factors in the leading order perturbative QCD. This unveils universal structure behind the SGP cross sections in a variety of hard processes, and also the special role of the scale invariance in the corresponding primordial cross section, which leads to remarkable simplification of the SGP cross sections for the...

Summary of alphas determinations at ZEUS

Claudia Glasman
The jet cross-section and structure-function measurements done with the ZEUS detector to extract the strong coupling constant and to test its energy-scale dependence are summarised. The values of alphas thus obtained and the HERA average are also presented.
