Narrative:

On final; a helicopter made a call to tower that they needed to cross over the departure end of the runway. The tower told them that there was an aircraft on short final and would be a touch and go; but by that point I was in my roundout and flare and did not hear the rest of the transmission. I was executing the go around when I looked up and saw the helicopter crossing the departure end. It became apparent that they were not moving fast enough out of the way and I could not climb above with a safe distance so I turned to the right and passed behind the helicopter and continued the pattern after. The problem seemed to be that the helicopter had the wrong aircraft in sight when he made the call; and did not see me.

Title: The private pilot on a touch-and-go took evasive action after a helicopter crossed the departure end of the runway. ATC had mentioned the touch-and-go traffic but it is possible that the helicopter pilot did not see the correct aircraft.
