Dip or nothingness of a Higgs resonance from the interference with a complex phase
Dip or nothingness of a Higgs resonance from the interference with a complex phase
We show that new resonance shapes---a pure dip, nothingness, and an enhanced pure peak---can be produced from the interference between the resonance and continuum with a relative phase. Production conditions of those new shapes are derived based on a general parametrization of the interference. The narrow width approximation is modified …
