Measurement of Polarization and Triple-Product Correlations in B -> phi K^* Decays
read the original abstract
We present measurements of decay amplitudes and triple-product correlations in B -> phi K^* decays based on 253 fb^-1 of data recorded at the Upsilon(4S) resonance with the Belle detector at the KEKB e^+ e^- storage ring. The decay amplitudes for the three different helicity states are determined from the angular distributions of final state particles. The longitudinal polarization amplitudes are found to be 0.45 +- 0.05 +- 0.02 for B^0 -> phi K^{*0} and 0.52 +- 0.08 +- 0.03 for B^+ -> phi K^{*+} decays. CP- and T-odd CP-violating triple-product asymmetries are measured to be consistent with zero.

Quantum Correlations in the Decay of $B^0$ meson and Entanglement Entropy
Phenomenological calculation of entanglement entropies in B0 → VV decays shows strong dependence on relative phases and a correlation with branching fractions that the authors link to weak and strong interaction dynamics.

Measurement of the branching fractions and longitudinal polarisations of $B^0_{(s)} \to K^{*0} \kern 0.18em \overline{\kern -0.18em K}{}^{*0}$ decays
LHCb measures f_L^d = 0.600 and f_L^s = 0.159 for B to K* Kbar* decays and reports a ratio L of 4.92 that confirms 4.4 sigma discrepancy with theory.
