Production of the X( 3872) in B-meson decay by the coalescence of charm mesons.
If the recently discovered charmonium state X( 3872) is a loosely bound S-wave molecule of the charm mesons D0 D(*0) or D(*0) D0, it can be produced in B-meson decay by the coalescence of charm mesons. If this coalescence mechanism dominates, the ratio of the differential rate for B+ -->D(0) D(* 0)K+ near the D0 D(*0) threshold and the rate for B+ -->XK+ is a function of the D0 D(*0) invariant ...
متن کاملNew states above charm threshold
In the short time since the Belle Collaboration reported sighting the “missing” charmonium state η c(2 S0) in exclusive B → KKSK π decays [1], new states associated with charmonium have appeared in great profusion. Apart from the long-sought hc(1 P1), recently observed by the CLEO Collaboration in the decay ψ(2S) → πhc → (γγ)(γηc) [2, 3], all the newly observed states lie near or above charm th...
متن کاملHeavy 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(...
متن کاملOpen Flavor Charmed Mesons
We present here recent results on the investigations of the mass spectrum ( S-states and P-states), decay constants, decay widths and life time of the D, Ds,and Bcmesons within the framework of phenomenological potential models.We also present the binding energy and the masses of the di-meson molecular systems with one or more charm meson combinations. Many of the newly found experimental open ...
متن کاملCombination of Colour Favoured and Colour
In this research we described the effective Hamiltonian theory and applied this theory to the calculation of current-current (Q1,2) and QCD penguin (Q3,…,6) c quark decay rates. We calculated the decay rates of semileptonic and hadronic of charm quark in the effective Hamiltonian theory. We investigated the decay rates of D meson decays according to Spectator Quark Model (SQM) for the calculati...
