Summary

Media data and Non-free use rationale
Description	Dark Photon decays into a pair of electron and positron.
Author or copyright owner	APS/Alan Stonebraker

Date of publication	November 10, 2014
Use in article (WP:NFCC#7)	Dual photon
Purpose of use in article (WP:NFCC#8)	To support encyclopedic discussion of this work in this article. The illustration is specifically needed to support the following point(s): The dark photon can potentially decay into electron-positron pairs.
Not replaceable with free media because (WP:NFCC#1)	n.a.
Minimal use (WP:NFCC#3)	Don't use more files per article/topic than necessary
Respect for commercial opportunities (WP:NFCC#2)	n.a.
Other information	Researchers have studied electron-positron (e+e−) collisions for interactions that produce a normal photon γ and a dark photon A′ that interacts with ordinary matter particles. The dark photon can potentially decay into an e+e− pair (shown here) or a μ+μ− pair (not shown). However, the latest results from the BaBar collaboration offer no sign of dark photons, thus placing new limits on these types of models.
