X ( 3872 ) diagnostics with decays to DD̄γ
نویسنده
چکیده
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) through the transition X(3872) → ψ(3770) γ. Thus an observation of the radiative decays of X(3872) to pairs of neutral and charged D mesons would provide an insight into the internal dynamics of the X(3872) resonance.

Properties of Exotic Charmonium-like States at CDF
We report the recent evidence for a new narrow structure, Y (4140), decaying to the J/ψφ final state, in exclusive B → J/ψφK decays in a data sample corresponding to an integrated luminosity of 2.7 fbcollected at the CDF II detector. This narrow structure with its mass well above open charm pairs is unlikely to be a candidate for a conventional charmonium state. From a study of the X(3872) mass...
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(...

New BABAR results on B mesons and quarkonia are presented: an analysis of B+ → X(3872)K+ and B0 → X(3872)K0 decays with X(3872) → J/ψπ+π−, a precise measurement of the B mass difference ΔmB = m(B0)−m(B+) and a study of hadronic transition between Υ mesons.
