Query: Interactions of two and three mesons including higher partial waves from
  lattice QCD   We study two- and three-meson systems composed either of pions or kaons at
maximal isospin using Monte Carlo simulations of lattice QCD. Utilizing the
stochastic LapH method, we are able to determine hundreds of two- and
three-particle energy levels, in nine different momentum frames, with high
precision. We fit these levels using the relativistic finite-volume formalism
based on a generic effective field theory in order to determine the parameters
of the two- and three-particle K-matrices. We find that the statistical
precision of our spectra is sufficient to probe not only the dominant $s$-wave
interactions, but also those in $d$ waves. In particular, we determine for the
first time a term in the three-particle K-matrix that contains two-particle $d$
waves. We use three $N_f=2+1$ CLS ensembles with pion masses of $200$, $280$,
and $340\;$MeV. This allows us to study the chiral dependence of the scattering
observables, and compare to the expectations of chiral perturbation theory.
