We define the QCD Husimi distribution as the phase space distribution of partons inside the nucleon. Compared to the more well-known Wigner distribution, the Husimi distribution is better behaved and positive. It thus allows for a probabilistic interpretation and can be used to define the ‘entropy’ of the nucleon as a measure of complexity of the partonic structure. A possible connection to the Color Glass Condensate approach at small-x is also discussed.
