Argh! A typo in my post. I meant second column. Sorry about that. One needs to implement the e/j and j/l removals.

Ah cool, that makes sense now.

In particle physics, we use a very handy system of units in which the speed of light equals 1 and the Planck constant equals 1. This implies that everything can be expressed in GeV (energy, momentum, mass, etc...) or 1/GeV (length, time, etc...) or actually some powers of GeV.

OK, but I'm still unsure how this affects the calculation in column 4.
I understand the Plt part but I'm not sure if the /GeV has any bearing.
Units are usually not explicitly indicated in formulas, right?
Or am I wrong and there is some kind of division to apply to Plt?

Thanks!
