DESCRIPTION:Speakers: 刘 占伟  (兰州大学)\nWe have studied the inte
 ractions between two heavy mesons [D^(*)-D^(*) or B^(*)-B^(*)] within heav
 y meson chiral effective field theory. The effective potentials are calcul
 ated with Weinberg's scheme up to one-loop level. At the leading order\, f
 our body contact interactions and one pion exchange contributions are cons
 idered. In addition to two pion exchange diagrams\, we include the one-loo
 p chiral corrections to contact terms and one pion exchange diagrams at th
 e next-to-leading order. The behaviours of effective potentials both in mo
 mentum space and coordinate space are investigated and discussed extensive
 ly. We notice the contact terms play important roles in determining the ch
 aracteristics of the total potentials. The possible molecular states are a
 lso investigated and the binding energies are provided by solving the Schr
 odinger equation.\n\nhttps://indico.itp.ac.cn/event/1/contributions/29/
