The rules for spin- 1 / 2 Dirac particles are as follows: The propagator is the inverse of the Dirac operator, the lines have arrows just as for a complex scalar field, and the diagram acquires an overall factor of −1 for each closed Fermi loop. If there are an odd number of Fermi loops, the diagram changes sign.
{{google|1 pound in kilograms {{=}}}} 1 pound in kilograms = Use Template:= to add an = sign to trigger Google Calculator when necessary; that template cannot be substituted. {{google|1 pound in kilograms}} 1 pound in kilograms: Google may display Calculator results for some expressions even if they lack a trailing equals sign.
The energy and momentum of an object measured in two inertial frames in energy–momentum space – the yellow frame measures E and p while the blue frame measures E ′ and p ′. The green arrow is the four-momentum P of an object with length proportional to its rest mass m 0.
A logarithmic chart allows only positive values to be plotted. A square root scale chart cannot show negative values. x: the x-values as a comma-separated list, for dates and time see remark in xType and yType; y or y1, y2, …: the y-values for one or several data series, respectively. For pie charts y2 denotes the radius of the corresponding ...
