Is right-handed current contribution to $B ˉ \to X_{u} l ν$ decays corrected by non-trivial vacuum in QCD?

Hiroyuki Umeeda

We study violation of quark-hadron duality for $B ˉ \to X_{u} l ν$ and $D \to X_{d} l ν$ decays in the presence of the right-handed current operator. For this case, we show that duality…

Theoretical aspects of $D^{0} - D ˉ^{0}$ mixing

Hiroyuki Umeeda

Observables in the $D^{0} - D ˉ^{0}$ mixing can be theoretically analyzed by the operator product expansion (OPE), in which $1/ m_{c}$ is regarded as an expansion parameter. Since the c…
