Aircraft X flashing to me climbing to 37;000 feet; so I called Sector X to see if they were working Aircraft X and they said no I said who is working him they said they have 'no idea'; I think Sector Y so then I call Sector Y to stop him but they say there not working them; then Sector X calls me and I proceed to stop Aircraft X at 31;000 feet for traffic. Sector Z calls me and apreq a flight that is climbing better than Aircraft X to keep him climbing to get over the top off him so I say approved. In the meantime Aircraft Y is climbing right in the face of Aircraft X at the same rate of climb; FL268; FL271; FL274; FL276; and so on now Aircraft X comes on my frequency climbing to FL310 so I proceed to turn him 30 degrees to the left who is in the face of Aircraft Y at the same altitude. The 30 degree turn avoided a near midair collision!Sector Z controller should have taken control of situation IN HIS OWN AIRSPACE!!!
Three different ARTCC sectors working three aircraft in confliction with each other. Very confusing scenario due to the different sectors taking point out coordination with different intentions to resolving the traffic conflictions instead of one controller working the aircraft with one plan for separation.
