Signal versus Background Interference in H+ → tb for MSSM Benchmark Scenarios

In this talk an investigation into the interference effects between the process pp →t bH + followed by the decay H + →tb and the background process pp → tt bb is presented. The level of interference in parts of the parameter space is shown to be high and as such it may spoil the results of typical analyses which treat signal and background as independent. This is shown for two benchmarks of the MSSM.
