Force carrier of quantum chromodynamics, like the photon is the force carrier of quantum electrodynamics.

One big difference is that it carrier itself color charge.

Color confinement Updated 2025-07-16

Can be thought as being produced from gluon-gluon lines of the Feynman diagrams of quantum chromodynamics. This is in contrast to quantum electrodynamics, in which there are no photon-photon vertices, because the photon does not have charge unlike gluons.

This phenomena makes the strong force be very very different from electromagnetism.

There seems to be no way without a pipe, you seem to need to reparse the columns, e.g. the tutorial at: csvkit.readthedocs.io/en/latest/tutorial/2_examining_the_data.html#csvgrep-find-the-data-you-need does:

csvcut -c county,item_name,total_cost data.csv | csvgrep -c county -m LANCASTER
