Reply to the Comment of X. Ji on "Do gluons carry half of the nucleon momentum?" [PRL 103:062001 (2009)]

Xiang-Song Chen, Wei-Min Sun, Xiao-Fu Lü +2

We affirm that the proper momentum defined in [PRL 103:062001 (2009)] does respect exact gauge symmetry and is as measurable as the kinetic momentum. The physical part of the gauge…

Do gluons carry half of the nucleon momentum?

Xiang-Song Chen, Wei-Min Sun, Xiao-Fu Lü +2

We examine the conventional picture that gluons carry about half of the nucleon momentum in the asymptotic limit. We reveal that this large fraction is due to an unsuitable definit…
