Narrative:

I was working R13 and descended aircraft X to tandy at 130. The aircraft (AC) was pointed out to sector 14. The R14 controller and I were surprised that an aircraft on the orcka departure auto popped climbing through 121 to 150 in sector 14's airspace without a point out from socal or from sector 18. We were unsure of who's responsibility that was and as to which controller had actually given the climb instruction or if the AC was climbing via a SID.I think it was the very next aircraft; aircraft Y; we (R14 and myself and the controller in charge) were watching because he had the same departure and sure enough that aircraft also auto popped to sector 14 and was now traffic from my tandy arrival. I called the traffic to aircraft X; who I was talking to; but was unsure of what altitude the other aircraft was climbing to. I then realized a loss of separation was going to occur. I told aircraft X to maintain visual separation from the traffic and he complied. If these aircraft are climbing out via a SID; that SID is not separated from 14's airspace. Socal or sector 18; must initiate a point out as those aircraft climbing are traffic for the tandy and leena arrivals. This is an unsafe situation that needs to be addressed as soon as possible. The sector 13 controller will not see the traffic auto pop until it is possibly too late. The aircraft climbing out on the orcka will auto pop to sector 14; then 14 has to call traffic to sector 13 for their arrivals.
