Reheating phase diagram for single-field slow-roll inflationary models
  We investigate the influence on the inflationary predictions from the
reheating processes characterized by the $e$-folding number $N_{\mathrm{reh}}$
and the effective equation-of-state parameter $w_{\mathrm{reh}}$ during the
reheating phase. For the first time, reheating processes can be constrained in
the $N_{\mathrm{reh}}\!-\!w_{\mathrm{reh}}$ plane from Planck 2015. We find
that for Higgs inflation with a nonminimal coupling to gravity, the predictions
are insensitive to the reheating phase for current CMB measurements. We also
find that the spontaneously broken SUSY inflation and axion monodromy inflation
with $\phi^{2/3}$ potential, which with instantaneous reheating lie outside or
at the edge of the $95\%$ confidence region in the $n_s\!-\!r$ plane from
Planck 2015 TT,TE,EE$+$lowP, can well fit the data with the help of reheating
processes. Future CMB experiments would put strong constraints on reheating
processes.
