     "The **production plane** (<font color=\"cyan\">cyan</font>) is defined by the momenta of the incoming particles that participate in the production of a particular state or particle. In the figure, we have $a+b \\to (R\\to 1+2)+3$ (subsystem $p_1+p_2$), meaning that the production plane is spanned by the momenta of $a$ (or $b$) and $1$.\n",
