Narrative:

I was working local control north during the event; and was controlling aircraft X. Aircraft X had initiated a go-around on runway 7L. The local south controller was controlling aircraft Y. Aircraft Y was on upwind for runway 7R. Aircraft Y informed the south controller that he experienced a near mid-air with aircraft X; who was on a go-around. Neither myself or the opposite controller saw any conflict. Recommendation; I would suggest that any time there is a go-around; that we issue traffic information to the opposite controller. This has not been an issue before. The only time go-around traffic may be an issue is when helicopters may be crossing low-level mid field.
