Pion Production by Parametric Resonance Mechanism with Quantum Back Reactions
Hideaki Hiro-Oka, Hisakazu Minakata
We investigate the problem of quantum back reactions due to particle production by the parametric resonance mechanism in an environment of nonequilibrium chiral phase transition. W…
Dynamical Pion Production via Parametric Resonance from Disoriented Chiral Condensate
Hideaki Hiro-Oka, Hisakazu Minakata
We discuss a dynamical mechanism of pion production from disoriented chiral condensates (DCC). It leads to an explosive production of pions via the parametric amplification mechani…
Superheavy Dark Matter and Parametric Resonance
Masato Arai, Hideaki Hiro-Oka, Nobuchika Okada +1
We propose a new scenario to produce the superheavy dark matter based on the inflationary universe. In our scenario, the inflaton couples to both a boson and a stable fermion. Alth…
Two Pion Correlations as a Possible Experimental Probe for Disoriented Chiral Condensates
Hideaki Hiro-Oka, Hisakazu Minakata
We discuss two-pion correlations as a possible experimental probe into disoriented chiral condensates. In particular, we point out that the iso-singlet squeezed states of the BCS t…
