Can Nearby Resonances Enhance D 0 − D̄ 0 Mixing ?

New Time Distributions of D-D̄ or B-B̄ Mixing and CP Violation

The formulae for D0-D̄0 or B0-B̄0 mixing and CP violation at the τ -charm or Bmeson factories are derived, for the case that only the decay-time distribution of one D or B meson is to be measured. In particular, we point out a new possibility to determine the D0-D̄0 mixing rate in semileptonic D decays at the Ψ(4.14) resonance; and show that both direct and indirect CP asymmetries can be measured ...

Possible Signals of D 0 - D̄ 0 Mixing and CP Violation

In view of the discovery potential associated with the future experiments of high-luminosity xed target facilities, B-meson factories and-charm factories, we highlight some typical signals of D 0-D 0 mixing and CP violation which are likely to show up in neutral D-meson decays to the semileptonic nal states, the hadronic CP eigenstates, the hadronic non-CP eigenstates and the CP-forbidden state...

Experimental Implications of Large CP Violation and Final State Interactions in the Search for D 0 − D̄ 0 Mixing

Parallel Session

A self-consistent coupled-channel approach is used to study the properties of D and D̄ mesons in hot dense matter. The starting point is a broken SU(4) s-wave Tomozawa-Weinberg DN (D̄N) interaction supplemented by an attractive isoscalar-scalar term. The Pauli blocking effects, baryon mean-field bindings, and π and open-charm meson self-energies are incorporated in dense matter at finite temperat...

We calculate the in-medium D meson self-energies in a hot pion gas induced by resonance interactions with pions. The appropriate resonances in the s, p and d waves of the D meson-pion pair are represented by low lying scalar, vector and tensor D∗ mesons. At temperatures around 200 MeV the D-meson mass drops by 30 MeV and the scattering width grows up to 60 MeV. Similar medium effects are found ...
