Description
A search is reported for heavy resonances decaying into e μ final
states in proton-proton collisions recorded by the CMS experiment at the
CERN LHC at √{s}=13 TeV, corresponding to an integrated luminosity
of 35.9 fb-1. The search focuses on resonance masses above
200 GeV. With no evidence found for physics beyond the standard model in
the e μ mass spectrum, upper limits are set at 95% confidence level
on the product of the cross section and branching fraction for this
lepton-flavor violating signal. Based on these results, resonant τ
sneutrino production in R-parity violating supersymmetric models is
excluded for masses below 1.7 TeV, for couplings λ 132
= λ 231 = λ 311 ' = 0.01.
Heavy Z' gauge bosons with lepton-flavor violating
transitions are excluded for masses up to 4.4 TeV. The e μ mass
spectrum is also interpreted in terms of non-resonant contributions from
quantum black-hole production in models with one to six extra spatial
dimensions, and lower mass limits are found between 3.6 and 5.6 TeV. In
all interpretations used in this analysis, the results of this search
improve previous limits by about 1 TeV. These limits correspond to the
most sensitive values obtained at colliders. [Figure not available: see
