چکیده

We investigate the decay mechanism in the B − → φφK − decay below charm threshold and in the neighborhood of the η c invariant mass region. Our approach is based on the use of factorization and the knowledge of matrix elements of the weak currents. For the B meson weak transition we apply form factor formalism, while for the light mesons we use effective weak and strong Lagrangians. We find that the dominant contributions to the branching ratio come from a combination of the matrix elements of the tree and the penguin operators. Our result for the branching ratio and Dalitz plot are in good agreement with the Belle measurement.

Backgrounds to 7 studies below charm threshold

Using DELCO data obtained at SPEAR, we evaluate the backgrounds to r+rdata samples below open charm threshold at the r-charm Factory (TcF). With a singletagging signature (electron and missing energy, Emiss), which is unique to the rcF, the backgrounds are found to be below 0.1%. 1 Requirements for future T data samples In order to make significant progress in r physics, future data samples mus...

Subthreshold photoproduction of charm

Charm photoproduction rates off nuclei below the nucleon threshold are estimated using the phenomenologically known structure functions both for x < 1 and x > 1. The rates rapidly fall below the threshold from values ∼10 pb for Pb close to the threshold (at 7.5 GeV) to ∼1pb at 6 GeV.

Combination of Colour Favoured and Colour

In this research we described the effective Hamiltonian theory and applied this theory to the calculation of current-current (Q1,2) and QCD penguin (Q3,…,6) c quark decay rates. We calculated the decay rates of semileptonic and hadronic of charm quark in the effective Hamiltonian theory. We investigated the decay rates of D meson decays according to Spectator Quark Model (SQM) for the calculati...

Production of the X( 3872) in B-meson decay by the coalescence of charm mesons.

If the recently discovered charmonium state X( 3872) is a loosely bound S-wave molecule of the charm mesons D0 D(*0) or D(*0) D0, it can be produced in B-meson decay by the coalescence of charm mesons. If this coalescence mechanism dominates, the ratio of the differential rate for B+ -->D(0) D(* 0)K+ near the D0 D(*0) threshold and the rate for B+ -->XK+ is a function of the D0 D(*0) invariant ...
