Partial decay widths of ϕ(2170) to kaonic resonances

نویسندگان

چکیده

In this work we study the strong decays of $\phi(2170)$ to final states involving kaonic resonances $K(1460)$, $K_1(1270)$ and $K_1(1400)$, on which experimental data have recently been extracted by BESIII Collaboration. The formalism developed here is based interpreting $K(1460)$ as arising from three-hadron dynamics, inspired our earlier works. For $K_1(1400)$ investigate different descriptions, such a mixture belonging nonet axial resonances, or former one state originating vector-pseudoscalar dynamics. ratios among partial widths $K^+(1460)K^-$, $K^+_1(1400)K^-$ $K^+_1(1270)K^-$ obtained are compatible with results, reinforcing three-body nature $\phi(2170)$. Within formalism, can also explain suppressed decay $K^*(892) \bar K^*(892)$, found Furthermore, results be useful in clarifying properties when higher statistics would available.

Gauge-Independent W -Boson Partial Decay Widths

We calculate the partial decay widths of theW boson at one loop in the standard model using the on-shell renormalization scheme endowed with a gauge-independent definition of the Cabibbo-Kobayashi-Maskawa (CKM) mixing matrix. We work in Rξ gauge and explicitly verify that the final expressions are independent of the gauge parameters. Furthermore, we establish the relationship between the on-she...

Masses, widths, and leptonic widths of the higher upsilon resonances.

The masses, total widths, and leptonic widths of three triplet s-wave bb states Y(4S), Y (5S), and Y(6S) are determined from measurements of the e+e annihilation cross section into hadrons for 10.55 & W & 11.25 GeV. The resonances are identified from potential model results and their properties are obtained with the help of a simplified coupled-channels calculation. We find M(4S) = 10.577 GeV, ...

Regularities in electromagnetic decay widths

We revisit Sakurai’s remark on the regularities of lepton-pair widths for mesons, extending the panorama to radiative X → γγ decays. The regularities persist, and somehow surprisingly some of them seem to relate with Fermi’s constant -or Z-. Back in 1978, Sakurai took the opportunity of a festscrift [11] to remark how the study of vector meson decays V → γ → ee, when extended to J/Ψ and Υ, seem...

Observation of Radiative B Meson Decays into Higher Kaonic Resonances

We have studied radiative B meson decays into higher kaonic resonances decaying into a two-body or three-body final state, using a data sample of 21.3 fb recorded at the Υ(4S) resonance with the Belle detector at KEKB. For the two-body final state, we extract the B → K∗ 2 (1430)γ component from an analysis of the helicity angle distribution, and obtain B(B0 → K∗ 2 (1430) 0γ) = (1.26± 0.66± 0.10...

Resonance trapping and saturation of decay widths

Resonance trapping appears in open many-particle quantum systems at high level density when the coupling to the continuum of decay channels reaches a critical strength. Here a reorganization of the system takes place and a separation of different time scales appears. We investigate it under the influence of additional weakly coupled channels as well as by taking into account the real part of th...
