Question
The derivative of one of these quantities with respect to the logarithm of the energy scale is the beta function, which describes the “running” of these quantities. For 10 points each:
[10m] Name this type of quantity, which characterizes the strength of an interaction.
ANSWER: coupling constant [or gauge coupling parameter, accept running of the coupling]
[10e] In a phenomenon called asymptotic freedom, this force becomes weaker at higher energy scales, according to quantum chromodynamics.
ANSWER: strong force [accept strong interaction or strong nuclear force; prompt on nuclear force]
[10h] The QCD potential between a quark and an antiquark contains two terms proportional to different powers of distance: a short-range term that resembles the QED potential and a long-range term that gives rise to confinement. Name both powers of distance found in the terms.
ANSWER: negative one and positive one
