New Evidence for a Four-Quark Structure of X Particles
نویسندگان
چکیده
Recent results by BELLE and BaBar point to the existence of a second X particle decaying in DD̄π, a few MeV above the X(3872). We identify the two X states with the neutral particles predicted by the 4-quark model and show that production and decays are consistent with this assignement. We consider the yet-to-beobserved charged partners and give new hints on how to look for them.

In this paper, we have considered that the strange-star consists of quark matter from its center to surface. For quark matter, we have used two models, the MIT bag model and string-flip like model. In the bag model, the energy of the system has been considered the kinetic energy of the particles of system in addition to a constant B. We have considered two states for B, one of them is constant...
متن کاملX-ray peak broadening analysis in LaMnO3+δ nano-particles with rhombohedral crystal structure
In this work, structural and magnetic properties of LaMnO3+δ compound prepared by citrate precursor method and annealed in presence of oxygen are investigated. The structural characterization of LaMnO3+δ by X-ray powder diffraction and using X’pert package and Fullprof program is evidence for a rhombohedral structure (R-3c space group) confirmed by FTIR measurement. The magnetic measurements sh...

A new nano-sized cobalt(II) coordination polymer, (CoL1).0.5DMF.1.5CH3OH(1); [H2L1 = 5-(4-Carboxy phenyl azo) salicyilic acid] has been synthesized by a sonochemical method. The thermal stability of compound 1 was studied by thermo- gravimetric and differential thermal analyses. Nano-structure of this coordination polymer was characterized by elementa...
متن کاملIndications of a four-quark structure for the X(3872) and X(3876) particles from recent Belle and BABAR data.
Recent results by Belle and BABAR point to the existence of a second X particle decaying in D(0)D(0)pi(0), a few MeV above the X(3872). We identify the two X states with the neutral particles predicted by the four-quark model and show that production and decays are consistent with this assignment. We consider the yet-to-be-observed charged partners and give new hints on how to look for them.
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(...
