On the likely dominance of WIMP annihilation to fermion pair+W/Z (and implication for indirect detection)

Thomas J. Weiler

Arguably, the most popular candidate for Dark Matter (DM) is a massive, stable, Majorana fermion. However, annihilation of Majorana DM to two fermions often features a helicity-sup…

On the manifold of closed hypersurfaces in R^n

Jan Pruess, Gieri Simonett

Several results from differential geometry of hypersurfaces in R^n are derived to form a tool box for the direct mapping method. The latter technique has been widely employed to so…
