You will only have to clear UK immigration, collect and then recheck bags and then reclear security if you book these as two separate flights i.e. ORD-LHR and then LHR-ARN as neither AA and BA won't through check on separate bookings

Otherwise the bags will be checked through and you can use the LHR connections process (see the connections planner on the LHR website for the process)
