Extracting α s from Electron – Positron Annihilation around 10 GeV
The total cross section for electron–positron annihilation into hadrons is calculated in the region just below the B meson threshold. QCD corrections up to third order, quark mass effects, initial state radiation, the running of α QED and the tails of the Υ resonances are included in the prediction. For given α s the prediction is accurate to 0.5 percent. An experimental measurement with the co...
متن کاملRadiatively driven electron - positron jets from two component accretion flows
Matter accreting onto black holes has long been known to have standing or oscillating shock waves. The post-shock matter puffs up in the form of a torus, which intercepts soft photons from the outer Keplerian disc and inverse Comptonizes to produce hard photons. The post-shock region also produces jets. We study the interaction of both hard photons and soft photons, with onaxis electron-positro...
متن کاملElectron/Positron Identification
This electron/positron identification variable summary will check our understanding of these particles’ behavior in the isolated Radiative Bhabha environment versus the highdensity hadronic environment of the CLEO detector.
متن کاملMagnetised Electron - Positron Plasmas
Electrostatic oscillations in cold electron-positron plasmas can be coupled to a propagating electromagnetic mode if the background magnetic field is in-homogeneous. Previous work considered this coupling in the quasi-linear regime, successfully simulating the electromagnetic mode. Here we present a stability analysis of the non-linear problem, perturbed from dynamical equilibrium , in order to...
متن کاملUltrarelativistic Electron-Positron Plasma
Ultrarelativistic electron-positron plasmas can be produced in high-intensity laser fields and play a role in various astrophysical situations. Their properties can be calculated using QED at finite temperature. Here we will use perturbative QED at finite temperature for calculating various important properties, such as the equation of state, dispersion relations of collective plasma modes of p...
