Hightlight of My Recent Research

The puzzle of excessive non-DD component of the inclusi-
ve ψ(3770) decay and the long-distant contribution

In our recent work, we suggested that the obvious discrepancy between theoretical prediction on the non-DD decays of ψ(3770) and data is to be alleviated by taking final state interaction (FSI) into account. By assuming that ψ(3770) overwhelmingly dissociates into DD, then the final state interaction induces a secondary process, we calculate the branching ratios of ψ(3770)→ DD→ J/ψη, ρπ, ωη, K*K, KK . Our results show that the branching ratio of ψ(3770)→ non-DD can reach up to Bnon-DD FSI=(0.4∼1.1)% while typical parameters I=0.4 GeV-2 and α=0.8∼1.1 are adopted. This indicates that the FSI is obviously non-negligible.

From my publication list as a theorist, you may have some idea of what I have been doing these years, namely, hadronic physics.

Porto (Douro river, D. Luis Iron Bridge)

In 11 January of 2008, I had a good trip for Porto with Dr. Duan-Jun Cai and took these beautiful photos. More pictures can be found in my photo album .
