Yes there could be, if they are traveling fast enough, relativistic time dilation would let their lifetimes appear quite long to non moving observers, like us.
Something that heavy moving that fast is going pack quite a wallop, nuclear effects aside.
Due to decay, a beam of Higgs bosons would eventually turn into something else, even if it was in their own time frame. I wonder if the Higgs mass impartation mechanism applies to Higgs bosons too? That these bosons also drag on the Higgs field?
