My Chinese colleague (Q) came back from Beijing, China. He is a close collaborator with Professor Close. After the seminar, we went for a glass of beer to celebrate the success of the first departmental seminar.
It was a beautiful English day, which proved that finally Spring has come. This year the arrival of Spring was very late, unusually late so that may people wrote articles about it. (This is ironical because people recently tend to do worry about too early arrival of Spring due to the global warming...)
We sat on the safa near the bright window, and started to have a chat. From it, I learned that the current hadron research centre is moving from the US to China, particularly, Beijing. The large, high-quality particle collider was launched several years ago in Beijing, and now it is running. According to Q, the tremendous amont of data are now produced from this fascility, and wait to be analysed. In his seminar, Professor Close also quoted several experimental works from Beijing. Probably, we need to pay attention to Beijing if we are interested in Quarkonium and Glueballs.
Thankfully, Q teaches me many things about the quark model. I hope I can do some work on this field soon. My attention is on Charmonium and Bottomonium, mesons consisting of two heaviest quarks. I hope non-relativistic approaches can be applied to these systems.
