Alleviating the Tension in the Cosmic Microwave Background using
  Planck-Scale Physics
  Certain anomalies in the CMB bring out a tension between the six-parameter
flat $\Lambda$CDM model and the CMB data. We revisit the PLANCK analysis with
loop quantum cosmology (LQC) predictions and show that LQC alleviates both the
large-scale power anomaly and the tension in the lensing amplitude. These
differences arise because, in LQC, the primordial power spectrum is scale
dependent for small $k$, with a specific power suppression. We conclude with a
prediction of larger optical depth and power suppression in the $B$-mode
polarization power spectrum on large scales.
