The Future of Electron - Positron

چکیده
This paper is an abbreviated version of a lecture given at the Snowmass meeting of the Division of Particles and Fields of the APS. Included here are SLAC's plans for the Stanford Linear Collider and my own + speculation on the development of the e e machines beyond the SLC or LEP that will be required to further advance the state of particle physics.

In this paper, we first study the conditions for the existence of the solitonic solutions in ion-electron-positron plasma. Then we investigate the effect of increasing positron on the solitonic wave properties, We also consider the time evolution of these waves in passing through the boundaries of two plasma with different positron densities and different positron-electron temperature ratios.
متن کاملLinear and Nonlinear Dust Acoustic Waves in Quantum Dusty Electron-Positron-Ion Plasma
The behavior of linear and nonlinear dust acoustic waves (DAWs) in an unmagnetized plasma including inertialess electrons and positrons, ions, and mobile positive/negative dust grains are studied. Reductive perturbation method is employed for small and finite amplitude DAWs. To investigate the solitary waves, the Korteweg–de Vries (KdV) equation is derived and the solution is presented. B...
متن کاملPET Radiopharmaceuticals
PET (positron emission tomography) is a powerful imaging technique that can provide quantitative information on the distribution of positron emitter labeled radiopharmaceuticals (PET radiopharmaceuticals) in the body. Positrons (ß+) are positively charged beta particles. They are emitted when the atom is proton rich. A positron has only a transient existence. After losing all of its kinetic ene...

Positron annihilation lifetime spectroscopy method with valuation of non-destructive investigation of material, provides information about electron density, defect concentration, type of defects and atoms around the defects. The stability of the system was tested with a source. The time resolution of the whole system has been derived about 365 ps at FWHM. Then n- and p-type silicon samples we...
