Final State Interaction In Decays
Cai-Dian Lü, Yue-Long Shen, Wei Wang
We study the final state interaction effects in decays. We find that the channel one-particle-exchange diagrams cannot enhance the branching ratios of $\bar{B^0}\to K…
Forming supermassive black holes by accreting dark and baryon matter
Jian Hu, Yue Shen, Yu-Qing Lou +1
Given a large-scale mixture of self-interacting dark matter (SIDM) particles and baryon matter distributed in the early Universe, we advance here a two-phase accretion scenario for…
Study of Decays with Polarization in Perturbative QCD Approach
Han-Wen Huang, Cai-Dian Lu, Toshiyuki Morii +3
The , decays are useful to determine the CKM angle . Their polarization fractions are also interesting since the polarization puzzle of the $B\to ϕK^…
B_s \to ρ(ω) K^* with Perturbative QCD approach
Jin Zhu, Yue-Long Shen, Cai-Dian Lu
are useful to determine the distribution amplitude, as well as constrain the CKM phase angle . We study these decays within the Perturbative QCD (P…
Polarization, CP Asymmetry and Branching ratios in B \to K^* K^* with Perturbative QCD approach
Jin Zhu, Yue-Long Shen, Cai-Dian Lu
We study the charmless rare decays within the Perturbative QCD picture. We calculate not only factorizable and non-factorizable diagrams, but also annihil…
Decay in Perturbative QCD Approach
Cai-Dian Lü, Yue-long Shen, Jin Zhu
The rare decay can occur only via penguin annihilation topology in the standard model. We calculate this channel in the perturbative QCD approach. The predicted branch…
