### Description

We discuss new striking resonance shapes of MSSM heavy Higgs bosons from the resonance-continuum interference with a relative phase: pure resonance dips, nothingness and enhanced pure peaks. We derive conditions for them and devise the modified narrow width approximation(NWA) to work with non-zero imaginary parts. Importantly, ttbar resonance searches at the LHC are crucially impacted. But we will show that the pure $A^0$ resonance dip is a particularly interesting signal; we can still search for it based on current search techniques (even without any interferences taken into account) and the modified NWA. ref: 1505.00291
