(quantum chromodynamics) In quantum chromodynamics with massless flavours, where the number of flavours is sufficiently small (i.e. small enough to guarantee asymptotic freedom, depending on the number of colours), an interacting conformal fixed point of the renormalization group where the value of the coupling is less than one (i.e. one can perform perturbation theory in weak coupling).

Japanese Meaning
Banks‐Zaks固定点とは、質量のないフレーバーを持つ量子色力学において、フレーバー数が十分に少なく（色数に依存し、非自明な漸近自由性を保証できるほど小さい場合）現れる、相互作用するコンフォーマルな（共形）固定点を指す。ここでは結合定数の値が1未満であり、これにより弱結合状態での摂動論が適用可能となる。
