Coupled-channel analysis of the possible , and molecular states
We perform a coupled-channel study of the possible deuteron-like molecules with two heavy
flavor quarks, including the systems of D (*) D (*) with double charm, B¯(*) B¯(*) with double …

Is X (3872) really a molecular state?
YR Liu, X Liu, WZ Deng, SL Zhu - The European Physical Journal C, 2008 - Springer
After taking into account both the pion and sigma meson exchange potential, we have
performed a dynamical calculation of the D 0 D̄* 0 system. The σ meson exchange …

Interactions of the doubly charmed state with a hadronic medium
We calculate the cross sections of the processes T cc+ π, T cc+ ρ→ D (∗) D (∗) and of the
corresponding inverse reactions. We use effective Lagrangians to account for the couplings …

Isospin breaking, coupled-channel effects, and
We reinvestigate the possibility of X (3872) as a DD¯* molecule with JPC= 1++ within the
framework of both the one-pion-exchange model and the one-boson-exchange model. After …

form factor reexamined
The D* D π form factor is evaluated in a QCD sum-rule calculation for both D and π off-shell
mesons. We study the Borel sum rule for the three-point function of one pseudoscalar, one …

Is a loosely bound molecular state?
X Liu, YR Liu, WZ Deng, SL Zhu - … Review D—Particles, Fields, Gravitation, and …, 2008 - APS
Since Z+(4430) lies very close to the threshold of D* D¯ 1, we investigate whether Z+(4430)
could be a loosely bound S-wave state of D* D¯ 1 or D* D¯ 1′ with JP= 0-, 1-, 2-, ie, a …
