Search for the process e+e−→η′(958) with the CMD-3 detector

A search for the process e+e−→η′(958) in the π+π−η→π+π−γγ final state has been performed with the CMD-3 detector at the VEPP-2000 e+e− collider. Using an integrated luminosity of 2.69 pb−1 collected at the center-of-mass energy Ec.m.=957.68 MeV we set an upper limit for the product of electronic wid...
