We present a new scheme for tagging high-pT bottom and charm jets using energetic muons. Contemporary track-based b tags lose their ability to reject light jet background as jet pT\rightarrowO(TeV), where the massive boost exposes fundamental limits in tracking resolution. For our "μx" tag, the signal efficiency and light jet rejection is robust versus pT. In the tested regime (jet pT∈[0.5,2.1] TeV), μx tags ∼14% of b jets, ∼6.5% of c jets and ∼0.65% of light jets. Since μx tagging should be immediately useful in a searches for heavy resonances, we test it with a typical dijet search --- a heavy, leptophobic Z′.
