Non-free media information and use rationale true for Quark
Description	The first event involving the Σ⁺ _c baryon, and thus charm quark. Recorded at Brookhaven National Laboratory in 1974. Photo on the left, annotated on the right. See source for explanation.

Article	Quark
Portion used	Entire
Low resolution?	No
Purpose of use	To illustrate a significant historical event in the history of particle physics, and in the establishment of the quark model
Replaceable?	Could be replaced by a picture involving the discovery of the J/ψ meson. But I don't know if these pictures even exist.
