Branching Ratio and Form Factor Measurements of 0 Beta Decay
نویسنده
چکیده
We present a branching ratio measurement for the beta decay of neutral Cascade hyperon, 0 ! + e e , using the KTeV detector at Fermilab. We used the principal decay mode of 0 ! 0 where ! p , as the ux normalization mode. The status of the measurement of the ratio of the axial-vector to vector coupling (g1/f1) for the Cascade beta decay will also be discussed. Furthermore, we present the preliminary branching ratio measurement for the muonic channel 0 ! + .

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...

We analyze three-body decays of and . Under the factorization approach, there are tree level diagrams for these decay modes and the transition matrix element of decay is factorized into a form factor multiplied by decay constant and form factor multiplied into weak vertices form factor. The transition matrix element of decay is also factorized into a form factor multiplied into weak vertic...
متن کاملRecent Results from the Ktev Experiment
We present recent preliminary results from five decay channels. From the KL → π πγ channel, we extract form factors for the CP violating M1 direct photon emission amplitude and the fraction of the total decay amplitude that is due to direct emission. We have placed an upper limit on the KL → π πγ branching ratio, and preliminary measurements of the KL → πeνee and π → ee branching ratios are pre...
متن کاملFinal State Interaction Effects in B+→J/ψ π+ Decay
In this research the exclusive decay of is calculated by QCD factorization (QCDF) method and final state interaction (FSI). First, the decay is calculated via QCDF method. The result that is found by using the QCDF method is less than the experimental result. So FSI is considered to solve the decay. For this decay, via the exchange of mesons are chosen for the intermedi...

We calculate D+ s → φ transition form factors V , A0, A1 and A2, and study semileptonic decay of D+ s → φl̄ν based on QCD sum rule method. We compare our results of the ratios of V (0)/A1(0), A2(0)/A1(0), ΓL/ΓT , and the total decay branching ratio of D+ s → φl̄ν with experimental data, and find that they are consistent.
