Measurement of the gluon polarization $\Delta g/g$ from Open Charm at COMPASS
We have measured the gluon polarization in the nucleon by detecting charm production via D$^{0}$ meson decay to charged K and $\pi$ in polarized muon scattering off a longitudinally polarized deuteron target. The dominant process for charm production is the photon gluon fusion into a charm anti-char...
