Аннотация
It is noted that in a number of authoritative publications (including reviews of the Particle Data Group) the Breit–Wigner formula for a resonance production cross section is erroneously given without the combinatorial factor of 2! that must be inserted in the case of collisions of identical particles—for example, when γγ collisions are considered.
