We investigate a dark sector coupled to the Standard Model (SM) through a kinetically mixed dark photon $U$ associated with a new $U(1)'$ gauge symmetry. Kinetic mixing $\varepsilon$ induces an effective coupling to the electromagnetic current, while $U$ interacts with stable dark matter (DM) $χ$ via a dark gauge coupling $g_χ$. [...]

Approved Technical Design Report for the Micro Vertex Detector of the Compressed Baryonic Matter experiment at FAIR..

The international accelerator facility for high-intensity hadron beams FAIR is under construction at GSI Darmstadt in Germany. In order to fulfill the users requests, schemes of manipulations of proton beams and heavy ion beams, consisting of longitudinal bunch merging and batch compression are proposed for the main synchrotron SIS100.
