Human Factors
After landing on in ZZZ; we were cleared to proceed to the gate. Upon arriving at [the] gate in ZZZ; a baggage cart was parked inside/on the Safety line. We requested Ground Crew to remove cart from Safety zone. While awaiting Ground Crew to complete removal of ground cart; aircraft was struck on the right side of the horizontal stabilizer by an aircraft attempting to maneuver behind us. Communication was established with the aircraft that struck us and confirmed the damage. Elected to shut down the aircraft in place and be towed into gate.
During taxi into the Gate we noticed that there was a baggage cart slightly over the right side Safety line. Since we had split-scimitar winglets; the Captain decided to hold on the gate centerline outside of the Safety Zone until Ground Ops moved the cart. While the cart was being moved we heard and felt a shudder to the aircraft. We could see a Company aircraft behind us so we asked Ground if they could see our aircraft to determine if we had contacted each other. The Crew from the other aircraft replied on the radio that they had clipped us.Our next actions were to determine the extent of the damage over the radio; remind the Passengers to remain seated and to alert the F/As (Flight Attendants) of our situation. The F/As said they felt the strike; but there were no abnormal situations in the cabin. After talking to the Crew behind us; the F/As and to Ground Control; we didn't feel there was an emergency situation; so we didn't call for emergency support. Although; since the full damage to our aircraft wasn't known; the Captain elected to shut down the engines and have the aircraft towed in to the gate. After shutting down the engines; we ran the Parking Checklist and called Ops to coordinate a tug. The aircraft behind us had clipped our right horizontal stabilizer with their left winglet and tore a piece of it off.After parking; the Captain called the Chief Pilot on Call to alert them and Dispatch of the situation. The Captain wrote up the defect and briefly talked with Maintenance; who took control of the aircraft after de-boarding. We then contacted scheduling to let them know we were told to stay with the aircraft.
Flight crews of two B737s reported a ground collision when the winglet of the taxiing aircraft struck the tail of the parked aircraft.
