No. 67 (2015): Future e+e- Ring Colliders

Issue Editor: Y. Funakoshi, Editor in Chief: W. Chou

The editor of this issue is Dr. Yoshihiro Funakoshi, a panel member and a senior scientist at KEK, Japan. The theme is “Future e⁺e^– Ring Colliders.” He collected 8 well-written articles, which cover four circular e⁺e^– colliders: DAФNE, SuperKEKB, CEPC and FCC-ee. The selection of this theme is timely as there is a world-wide renewed interest in our community in future circular colliders. Another issue dedicated to future circular hadron colliders (FCC-pp and SPPC) will appear in April 2017.
