Two Comparative Case Studies of b-quark and c-quark Physics: • Particle-antiparticle Mixing • Radiative Weak Decays
Dollar mixed weak radioactive decay D meson pseudo-scalar meson particle antiparticles
2014/12/23
We discuss prospects for detecting the two charm-related phenomena of $D^0$-${\bar D}^0$ mixing and weak radiative decays of $D$ mesons ({\it e.g.} $D\to K^* + \gamma$). A general update of particle-a...

2014/12/23
We address standard model predictions for flavor-changing radiative transitions of the pseudoscalar charm mesons. Short-distance contributions in D radiative transitions are contrasted with those in B...
