Gluon polarization in the nucleon from quasi-real photoproduction of high-pT hadron pairs
COMPASS Collaboration, E. S. Ageev
We present a determination of the gluon polarization Delta G/G in the nucleon, based on the helicity asymmetry of quasi-real photoproduction events, Q^2<1(GeV/c)^2, with a pair of…

Search for the Phi(1860) Pentaquark at COMPASS
E. S. Ageev
Narrow Xi-pi+- and Xi-bar+pi+- resonances produced by quasi-real photons have been searched for by the COMPASS experiment at CERN. The study was stimulated by the recent observatio…
