Exact baryon-meson relation for $b \to s ν ν ˉ$

Teppei Kitahara, Manas Kumar Mohapatra, Kota Sasaki

We derive an exact relation among the normalized branching fractions of $Λ_{b} \to Λ ν ν ˉ$ and $B \to K^{(*)} ν ν ˉ$ , within the lepton-number-conserving effective Hamiltonian i…

Complete one-loop QED corrections to $D_{s}^{+}$ leptonic decays and impact on the CKM unitarity test

Teppei Kitahara, Jun Miyamoto, Kota Sasaki

Recently, a violation of the CKM unitarity condition has been reported in the latest charm-meson data and the latest lattice results, once the universal electroweak correction is t…
