Search for lepton-flavor violating decays of heavy resonances and quantum black holes to eμ final states in proton-proton collisions at √s=13 TeV
A search is reported for heavy resonances decaying into eµ 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 fou...

description |
A search is reported for heavy resonances decaying into eµ 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 eµ 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 λ132 = λ231 = λ
0
311 = 0.01.
Heavy Z0 gauge bosons with lepton-flavor violating transitions are excluded for masses up
to 4.4 TeV. The eµ 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 |
