The 55th ICFA Advanced Beam Dynamics Workshop on High Luminosity Circular e+e- Colliders – Higgs Factory (HF2014) will take place on October 9-12, 2014 in Beijing, China. It will be hosted by the Institute of High Energy Physics (IHEP), Chinese Academy of Sciences (CAS). Since the discovery of the Higgs particle in 2012 at CERN, there have been two new initiatives for a very large future circular collider, namely, the FCC in Europe and the CEPC-SppC in China. Both would serve as a Higgs factory in the first stage. ICFA encouraged these initiatives and issued a statement that “ICFA supports studies of energy frontier circular colliders and encouraged global coordination.” The HF2014 workshop will focus on a circular e+e- collider for a Higgs factory.
