STUDY OF THE PROCESS e+e- → K+K-π+π- WITH THE CMD-3 DETECTOR AT THE VEPP-2000 e+e- COLLIDER

We report preliminary results on the measurement of the cross section of the process e+e- → K+K-π+π- in the c.m. energy range from 1.5 GeV to 2 GeV. It is shown that the cross section is dominated by the contributions of several intermediate states K+K-ρ, K*Kπ, ϕπ+π- and K*K*.
