Effects of final state interaction in B^+_c to D^0 K^+ decay

In this paper, the decay of Bc+ meson, which consists of two b and c heavy quarks, into the Do and K+  mesons was studied. Given that the experimental branching ratio for this decay was within the range of 3.75*10-5 to 11.16*10-5; it was decided to calculate the theoretical branching ratio by applying the final state interaction (FSI) through the T and cross-section channels. In this process, b...

the effects of changing roughness on the flow structure in the bends

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...

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...

Electromagnetic decay of ( 1520 )

The electromagnetic decay processes of excited hyperon states are a very sensitive probe of the structure of hyperons. We will argue that the recent measurements of electromagnetic decay rates indicate that the wave functions of the hyperon ground states should contain sizable components of excited quark states (configuration mixing). Flavor-SU(3) is a broken symmetry and it appears that the hy...

Large Effects of CP- and T-Violation in K Decay

The ǫ-impurity of the KL wave-function gives rise to a huge CP -violating effect in the decay KL → π πγ which is hidden in the polarization state (Stokes vector) of the photon. One component of the Stokes vector is CP -odd and T -even, and may be identified with circular polarization. Another component is CP -odd and T -odd (“oblique polarization”) and reveals itself as a large asymmetry (14%) ...
