چکیده

In this talk, we review our recent work about the dynamical studies of Z+(4430) and X(3872). Z+(4430) can not be explained as a D1D ∗ or D1D∗ molecular state only considering one pion exchange potential without the cutoff, which needs to be confirmed by introducing sigma exchange potential and adding the cutoff in the effective potential. One also excludes the possibility of X(3872) as a DD∗ molecular state by one pion and one sigma exchanges with the cutoff. Fortunately there exists an S-wave BB∗ bound state with JPC = 1++. we suggest future experiment to search this state.

How Resonances can synchronise with Thresholds

The mechanism by which a threshold may capture a resonance is examined. It involves a threshold cusp interfering constructively with either or both (i) a resonance produced via confinement, (ii) attractive tand u-channel exchanges. The f0(980), X(3872) and Z(4430) are studied in detail. The f0(980) provides a valuable model of the locking mechanism. The X(3872) is too narrow to be fitted by a c...

Heavy quark meson spectroscopy at CDF

With growing datasets collected by the CDF II experiment, studies of the spectroscopy of mesons containing heavy quarks become more exciting. The CDF experiment has good capabilities in both charm and bottom sector. This capability allowed also to contribute to the study of the zoo of states called X,Y, Z. In this area we present a recent update of the mass measurement of X(3872). The result m(...

New Charmonium-like States at B-Factories

Several new states have been discovered in the last few years [2], most of them at B-factories. The B-factories provide a clean environment to search for and study these new particles either in B meson decays or in the production in ee reactions with initial state radiation. In this article the recent analyses of new states in B decays are presented. Both experiments, BaBar and Belle, together ...

S ep 2 00 7 Z + ( 4430 ) as a cusp in D ∗ ( 2010 ) D 1 ( 2420 )

The Z(4430) observed by Belle is explained naturally as a threshold cusp in the D(2010)D1(2420) system. PACS numbers: 13.25.Gv, 13.25.Hw, 14.40.Gx. 14.40.Nd The Belle collaboration reports a peak in the Ψπ mass spectrum in B → ΨπK. The remarkable feature of this peak is that it has isospin 1, unlike regular cc̄ states, so it is exotic. They fit it as a resonance with mass M = 4433± 4± 1 MeV and ...

X ( 3872 ) diagnostics with decays to DD̄γ

It is pointed out that in the decays X(3872) → D ¯ Dγ the possible 'molecular' component of the X(3872) should give rise essentially only to a D 0 ¯ D 0 γ final state with a predictable spectrum, and should yield virtually no contribution to decays into D + D − γ. The latter final state with charged D mesons should however arise from the radiative decays of the short-distance core of the X(3872...
