Query: Anomalous dimension of the gauge invariant canonical decomposition for
  proton momentum with the background field method   The anomalous dimension for the gauge-invariant-canonical decomposition of
the energy-momentum tensor for quarks and gluons is studied by the background
field method. In particular, the consistency between the background field
method and the renormalization in the gluonic sectors is investigated. The
analysis shows that the naive gauge-invariant-decomposition has an
inconsistency between its definition and the renormalization in the background
field method. Although we try to consider a trick to overcome this
inconsistency in computing the anomalous dimension, the gauge-parameter
dependence remains in the final result. This result should be extended to the
problems on the gauge-invariant-canonical-spin decomposition.
