Query: $B$-hadron fragmentation functions at next-to-next-to-leading order from
  global analysis of $e^+e^-$ annihilation data   We present nonperturbative fragmentation functions (FFs) for bottom-flavored
($B$) hadrons both at next-to-leading (NLO) and, for the first time, at
next-to-next-to-leading order (NNLO) in the $\overline{\mathrm{MS}}$
factorization scheme with five massless quark flavors. They are determined by
fitting all available experimental data of inclusive single $B$-hadron
production in $e^+e^-$ annihilation, from the ALEPH, DELPHI, and OPAL
Collaborations at CERN LEP1 and the SLD Collaboration at SLAC SLC.
  The uncertainties in these FFs as well as in the corresponding observables
are estimated using the Hessian approach.
  We perform comparisons with available NLO sets of $B$-hadron FFs.
  We apply our new FFs to generate theoretical predictions for the energy
distribution of $B$ hadrons produced through the decay of unpolarized or
polarized top quarks, to be measured at the CERN LHC.
