Basic features of the pion valence-quark distribution function

Basic features of the pion valence-quark distribution function

The impulse-approximation expression used hitherto to define the pion's valence-quark distribution function is flawed because it omits contributions from the gluons which bind quarks into the pion. A corrected leading-order expression produces the model-independent result that quarks dressed vi...
