K-matrix analysis of the (IJ^{PC}=00^{++})-wave in the mass region below 1900 MeV

open access: yes, 2002
We present the results of the current analysis of the partial wave IJ^{PC}=00^{++} based on the available data for meson spectra (pi-pi, K\bar K, eta-eta, eta-eta', pi-pi-pi-pi).

$X(1835)$ and the New Resonances $X(2120)$ and $X(2370)$ Observed by the BES Collaboration

open access: yes, 2010
We calculate the decay widths of both the second and the third radial excitations of $\eta$ and $\eta'$ within the framework of $^3P_0$ model. After comparing the theoretical decay widths and decay patterns with the available experimental data of $\eta ...

Implications for $B \to \eta K$ and $B \to Glueball + K$ Modes from Observed Large $B\to \eta' K+X$

open access: yes, 1997
The unexpectedly large branching ratios for $B\to \eta' K (\eta' X_s)$ decays could be of gluonic origin. We study the implications for $B\to \eta K (\eta X_s)$ and $P K (PX_s)$, where $P$ is the pseudoscalar glueball.

chi(c0) and chi(c2) decays into eta eta, eta eta ', and eta 'eta ' final states

open access: yes, 2007
Using a sample of 3x10(6) psi(2S) decays collected by the CLEO III and CLEO-c detector configurations, we present results of a study of chi(c0) and chi(c2) decays into eta eta, eta eta('), and eta(')eta(') final states. We find B(chi(c0)->eta eta)=(0.31 +/- 0.05 +/- 0.04 +/- 0.02)%, B(chi(c0)->eta

Composition of the Pseudoscalar Eta and Eta' Mesons

open access: yes, 2007
The composition of the eta and eta' mesons has long been a source of discussion and is of current interest with new experimental results appearing. We investigate what can be learnt from a number of different processes: V to P gamma and P to V gamma (V ...

International experience of petroleum IT creation

open access: yesGeoresursy, 2018
The international market is full of high-quality solutions for reservoir modeling provided by specialized service and consultancy companies. Nevertheless, oil and gas operators independently develop their own home-made software solutions, although, at ...

Radiative $\phi$$-$meson decays and $\eta$-$\eta^\prime$ mixing: a QCD sum rule analysis

open access: yes, 2000
The radiative transitions $\phi \to \eta \gamma$ and $\phi \to \eta^\prime \gamma$ are analysed using QCD sum-rules. The results we obtain for ${\cal B}(\phi \to \eta \gamma)=(1.15 \pm 0.2) 10^{-2}$ and ${\cal B}(\phi \to \eta^\prime \gamma)=(1.18 \pm 0 ...

Hybrid CNN-Ensemble Framework for Intelligent Optical Fiber Fault Detection and Diagnosis

open access: yesIEEE Open Journal of the Communications Society
Ensuring the integrity and reliability of optical fiber networks is essential for modern global communication systems, as faults such as fiber cuts, malicious tapping, and connector degradation can result in significant service disruptions and security ...
