Query: Heteronuclear Efimov scenario with positive intraspecies scattering
  length   We investigate theoretically and experimentally the heteronuclear Efimov
scenario for a three-body system that consists of two bosons and one
distinguishable particle with positive intraspecies scattering lengths. The
three-body parameter at the three-body scattering threshold and the scaling
factor between consecutive Efimov resonances are found to be controlled by the
scattering length between the two bosons, approximately independent of
short-range physics. We observe two excited-state Efimov resonances in the
three-body recombination spectra of an ultracold mixture of fermionic $^6 $Li
and bosonic $^{133} $Cs atoms close to a Li-Cs Feshbach resonance, where the
Cs-Cs interaction is positive. Deviation of the obtained scaling factor of
4.0(3) from the universal prediction of 4.9 and the absence of the ground state
Efimov resonance shed new light on the interpretation of the universality and
the discrete scaling behavior of heteronuclear Efimov physics.
