Discovering True Muonium at LHCb
We study the potential of the LHCb experiment to discover, for the first
time, the true muonium bound state. We propose a search for the
vector state, , which kinetically mixes with the
photon and dominantly decays to . We demonstrate that a search for
, in a displaced
vertex can exceed a significance of 5 standard deviations assuming statistical
uncertainties. We present two possible searches: an inclusive search for the
vertex, and an exclusive search which requires an additional photon
and a reconstruction of the mass.Comment: 12 pages, 5 figures; v2: edits from comments and review, matched to
