Query: Probing the quantum interference between singly and doubly resonant
  top-quark production in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS
  detector   This Letter presents a normalized differential cross-section measurement in a
fiducial phase-space region where interference effects between top-quark pair
production and associated production of a single top quark with a $W$ boson and
a $b$-quark are significant. Events with exactly two leptons ($ee$, $\mu\mu$,
or $e\mu$) and two $b$-tagged jets that satisfy a multi-particle invariant mass
requirement are selected from $36.1$ fb$^{-1}$ of proton-proton collision data
taken at $\sqrt{s}=13$ TeV with the ATLAS detector at the LHC in 2015 and 2016.
The results are compared with predictions from simulations using various
strategies for the interference. The standard prescriptions for interference
modeling are significantly different from each other but are within $2\sigma$
of the data. State-of-the-art predictions that naturally incorporate
interference effects provide the best description of the data in the measured
region of phase space most sensitive to these effects. These results provide an
important constraint on interference models and will guide future model
development and tuning.
