Dec 9, 2015 at 10:13 comment added user3130648 Is it a 4D field? And if yes, does it have spatial limits?
Dec 9, 2015 at 10:10 comment added John Rennie @user3130648: the various types of quarks are excitations of the corresponding quark quantum fields. There is a quantum field for all the elementary particles.
Dec 9, 2015 at 10:05 comment added user3130648 So what about quarks?
Dec 9, 2015 at 9:30 comment added John Rennie @Omry: any parton can collide with any other parton.
Dec 9, 2015 at 9:29 comment added John Rennie @user3130648: the proton is not an elementary particle so it doesn't have a corresponding quantum field.
Dec 9, 2015 at 9:25 comment added Omry Can't sea quarks also contribute to the collision?
Dec 9, 2015 at 9:07 comment added user3130648 In what field does a proton live?
