Manuel, If you look at the left hand side of your definition in full form you will see that the v sub 0 pattern is not actually a pattern at all. test[Times[Blank[], Subscript[v, 0]], Pattern[\[Gamma], Blank[]], Pattern[H, Blank[]], Pattern[m, Blank[]]] The simplest solution is just to use v0 (without a subscript) in the definition. After all, it is only a dummy variable anyway.
