Semiexclusive production in electron-positron annihilation.
We present a thorough analysis of the direct semiexclusive production in quantum chromodynamics (QCD) of single, highly isolated mesons from electron-positron or two-photon initial states. Corrections of higher order and of subleading twist are considered, and potential divergences in the naive calculation are contained. Monte Carlo methods are used to relate the QCD calculations to experimenta...
متن کاملFinal–state Radiation in Electron–positron Annihilation into Pion Pair
In this article the final-state radiation (FSR) of the hard photon in e−(p1) + e(p2) → γ ∗(Q) → π(p+) + π −(p−) + γ(k) reaction is considered in the framework of ChPT with vector ρ and axial–vector a1 mesons 1) (the FSR diagrams are shown in Fig.1). Our consideration of FSR is motivated by the necessity to study model dependence of the next-to-leading order hadronic contribution a μ to anomalou...
متن کاملObservation of exclusive electron-positron production in hadron-hadron collisions.
We present the first observation of exclusive e(+)e(-) production in hadron-hadron collisions, using pp[over] collision data at (square root) s = 1.96 TeV taken by the run II Collider Detector at Fermilab, and corresponding to an integrated luminosity of 532 pb(-1). We require the absence of any particle signatures in the detector except for an electron and a positron candidate, each with trans...
متن کاملElectron–Positron Pair Production by Electromagnetic Pulses
Electron–positron pair production in vacuum by a single focused laser pulse and by two counterpropagating colliding focused pulses is analyzed. A focused laser pulse is described using a realistic threedimensional model based on an exact solution of Maxwell’s equations. In particular, this model reproduces an important property of focused beams, namely, the existence of two types of waves with ...
متن کاملPrototype Graphs for Radiative Corrections to Polarized Chargino or Neutralino Production in Electron-Positron Annihilation
We present the contributions from all types of one-loop corrections to the scattering amplitude for the pair production of polarized charginos or neutralinos from polarized electron-positron annihilation. The contributions are classified in terms of “prototypes” distinguished by the number of particles inside the loops and their spins. The results are quoted in terms of the Veltman-Passarino fu...
