Charm - Production in e + e − Annihilation Around 4 GeV
نویسنده
چکیده
Using the CLEO-c detector at the Cornell Electron Storage Ring, we have measured inclusive and exclusive cross sections for the production of D, D and D s mesons in e + e − annihilations at thirteen center-of-mass energies between 3.97 and 4.26 GeV. Exclusive cross sections are presented for final states consisting of two charmed mesons (DD̄, D∗D̄, D∗D̄∗, D s D − s , D ∗+ s D − s , and D ∗+ s D ∗− s ) and for processes in which the charmed meson pair is accompanied by a pion.

In this paper, we investigate the multiplicity of charged particles in e+ e– annihilation by using different models. To achieve this we first fit the multiplicity distribution of charged particles in the energy range of 54-57 GeV by using both the Poisson distribution and KNO scaling, then we compare these results with multiplicity distribution at the lower energies. This comparison shows that...
متن کاملSupersymmetry with R - Parity Breaking : Contact Interactions and Resonance
In supersymmetric theories with R-parity breaking, trilinear couplings of two leptons to scalar sleptons are possible. In electron{positron collisions such interactions would manifest themselves through contact terms in Bhabha scattering , e + e ? ! e + e ? , and in the annihilation to lepton pairs, e + e ? ! + ? and + ?. Interpreting the high x, high Q 2 DIS HERA events as charm squark product...
متن کاملInclusive lepton production in e+e- annihilation at 29 GeV.
We use data taken by the Mark II detector at the PEP storage ring to study inclusive lepton production in e+eannihilation at 29 GeV. From fits to the inclusive lepton momentum and transverse momentum spectra we measure the semileptonic branching ratios for charm and bottom hadrons. We also determine with good precision the mean value of the bottom fragmentation function using both electron and ...
متن کاملInterpretations for the X(4160) observed in the double charm production at B factories
Belle Collaboration has recently observed a new state, the X(4160), in the process of double charm production e+e− → J/ψ + X(4160) followed by X(4160) → D∗D̄∗. We discuss possible interpretations for the X(4160), firstly the D-wave spin-singlet charmonium state D2(2D) (with J PC = 2−+), which is produced via e+e− annihilation into a single photon. We then discuss the possibility that the X(4160)...
