Search for direct production of a 2 ( 1320 ) and f 2 ( 1270 ) mesons in e + e − annihilation

A search for direct production of C-even resonances a2(1320) and f2(1270) in e e annihilation was performed with SND detector at VEPP-2M ee collider. The upper limits of electronic widths of these mesons were obtained at 90% confidence level: Γ(a2(1320) → e e) <0.56 eV, Γ(f2(1270) → e e) <0.11 eV. PACS: 13.40.Gp; 13.65.+i; 13.85.Rm; 14.40.Cs

the search for the self in becketts theatre: waiting for godot and endgame

this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...

Electroweak Corrections to Four-Fermion Production in ee Annihilation

The recently completed calculation of the full electroweak O(α) corrections to the charged-current four-fermion production processes ee → ντ τμν̄μ, ud̄μ−ν̄μ, and ud̄sc̄ is briefly reviewed. The calculation is performed using complex gauge-boson masses, supplemented by complex couplings to restore gauge invariance. The evaluation of the occurring one-loop tensor integrals, which include 5and 6-point ...

Secondary Heavy Quark Pair Production in ee Annihilation

The multiplicity of heavy quarks from gluon splitting in ee annihilation has now been theoretically calculated and experimentally measured at LEP. However, the experimental measurement requires theoretical input for the shape of the multiplicity with respect to an event shape. In this paper we calculate the multiplicity of heavy quarks from gluon splitting in ee annihilation as a function of th...

Exclusive production of heavy mesons in e+e- annihilation.

Within the framework of a particular model for meson production, we have performed a perturbative QCD analysis for exclusive pair production of heavy mesons. Analytic calculations of angular distributions for pseudoscalar-pseudoscalar, vector-pseudoscalar and vector-vector mesons are presented. Numerical estimates of the cross section, angular distributions and forward-backward asymmetry for va...
